Slough Fort Paranormal Investigation – Case Study
On Saturday 11th October 2025, KASE Paranormal carried out an overnight paranormal investigation at Slough Fort, Allhallows-on-Sea, Kent. Working in small teams, we spent the night moving between the courtyard, Guard Room, lower magazine and surrounding areas, documenting anything that might help answer a simple question: is Slough Fort haunted, and if so, what kind of activity is taking place?
This case study gives a clear, non-sensational overview of how we approached the night, what methods we used, and the most interesting results from our time at Slough Fort.
Quick Case Overview
Location: Slough Fort, Allhallows-on-Sea, Kent
Type of site: Victorian coastal artillery fort overlooking the Thames Estuary
Date: Saturday 11th October 2025
Time: 6:00 pm to 2:00 am
Teams on site:
Team A: Dan, Darren, Jake and Laura (in order to avoid contamination, Laura has no previous knowledge of new locations)
Team B: Sue, Rick, Lucy, Sam and Lee
Aim of the investigation:
To carry out a structured overnight investigation at Slough Fort, building on previous visits, and to document any repeatable patterns of activity in key areas such as the courtyard, Guard Room and lower magazine.
Most active areas:
Guard Room
Lower magazine
Courtyard and entrance area, including the route to the toilet block
Key findings:
Clear audible response of a male voice saying “Yeah” in direct answer to a question (“Is William here?”), captured on camera in the lower magazine.
Multiple reports of physical contact, shared aches and pains and sudden relief when people moved away from certain spots.
Cat balls and laser grid reacting on request, especially in the lower magazine and Guard Room.
Repeated footsteps, bangs and “chase” behaviour in the lower magazine, matching patterns from earlier investigations.
A strange swooping shape on camera at a doorway, with no obvious physical explanation, in the same area where a white face had been seen retreating.
This was a full, structured paranormal investigation at Slough Fort in Kent; KASE Paranormal does not offer public ghost tours.
About Slough Fort
Slough Fort is a Victorian coastal artillery fort in Allhallows-on-Sea, Kent, originally built to protect the Thames Estuary and approaches to London. Today it is maintained by a volunteer team and used for tours, events and ongoing restoration.
Over the years, visitors, staff and investigators have reported:
Footsteps and movement in empty rooms
A sense of being watched in the courtyard and Guard Room
Voices and unexplained noises in the lower magazine
Previous paranormal investigations have suggested a mixture of possible intelligent interaction and residual or looping patterns, which is why we returned for a more structured case study.
How We Ran The Investigation
To avoid overcrowding any single area and to keep things as controlled as possible, we split into two teams and rotated between key parts of the fort.
Across the night we focused on:
Courtyard and surrounding rooms
Guard Room and adjoining cells
Lower magazine and tunnel entrance
External areas near the toilet block and car park
Equipment used
We used a mix of environmental and interaction-based tools:
Motion activated lights (existing site lights)
K2 meters and other EMF detectors
Rem Pod
Spirit Box
Laser grid
Cat balls
Static cameras
Voice recorders
Radios and selected investigative apps
Documentation
Baseline readings and environmental notes were taken at the start of the night.
Both teams logged timestamps for their observations, which later allowed us to cross check activity between areas.
Conditions On The Night
Understanding the conditions helps rule out normal causes before anything is classed as unexplained.
Weather and environment
Weather: Clear to partly cloudy throughout the evening
Temperature: Around 12°C at 6 pm, dropping to about 8°C by 2 am
Wind: Light easterly breeze (around 5–7 mph)
Humidity: Moderate, around 70%
Moon phase: Waxing gibbous, roughly 77% illumination, providing good natural light and visibility
Possible sources of contamination
Ongoing refurbishment and freshly painted surfaces within the fort
Occasional aircraft noise
Normal background sounds from the wider site and access areas
People occasionally walking to and from the toilet block
We noted all of these factors during the night so we could filter out what was likely environmental before focusing on anything that remained unexplained.
Key Activity By Area
Courtyard, Entrance And Surrounding Rooms
Initial walkaround
On arrival, venue staff member Sarah escorted Dan and Laura into the courtyard for an initial walkthrough while the rest of the team were on their way.
Key moments from this first pass:
In the Guard Room, Laura noticed a rope on the floor inside one of the cells. She had previously described this same rope and its position during a team meeting earlier in the year, before visiting the location. Sarah confirmed the rope should not have been there, which supported the accuracy of that earlier impression.
Walking through towards the café, Laura sensed an intelligent male presence within the locked rooms to the right of the courtyard entrance, along with a heavy, oppressive atmosphere in that doorway area.
Later, while seated in the café area, Dan and Laura both heard footsteps passing through the main entrance, as if someone was walking towards them. Expecting another team member to appear, they looked up. Nobody entered, and the rest of the team were confirmed to still be in their vehicles outside.
External activity and motion light
In the wider outside area near the toilet block and car park, Team A noted:
A motion activated security light near the toilet block turning on without any obvious cause. The team tested this repeatedly, watching for people, animals and passing vehicles, but could not find a consistent trigger.
Audible noises such as what sounded like a wooden crate or box being dropped in the main entrance area. When they investigated, nothing was disturbed. The only way to recreate the sound was to deliberately kick a crate in the room.
While some of this may still have a normal explanation, the timing and difficulty in replicating certain events made them worth logging.
Names and impressions
As the night progressed around the courtyard and entrance:
Dan heard a door rattle from the same room where earlier noises had been reported.
Shortly after Darren commented that spirits can draw from our energy, Laura heard the words “It’s not allowed” in her head, and the app immediately displayed “You are protected.”
Back in the courtyard, Dan intuitively received the name “George”, which he could not shake. The app then produced “Black hair”, and when Darren joined from across the courtyard he independently sensed a male presence with black, greasy hair on the stairs.
From the upper level, the team heard a loud thud from one of the middle casemates on the right-hand side of the courtyard, followed by another unclear sound. Taken together with the motion light activity, the group felt there might be a looping or residual pattern here, with the sense of being observed rather than directly engaged.
Guard Room
When the teams swapped over, Team B moved into the Guard Room and activity increased again.
Physical sensations and atmosphere
Shortly after a cat ball activated on its own, both Sam and Lee began to experience pronounced neck stiffness, which worsened while they sat between the two adjoining cells.
At about 11:47 pm, Lee reported a sharp pain on the left side of his neck and arm, describing it as similar to a cardiac episode. When he moved away from that specific area, the symptoms eased.
Around 12:05 am, Ricky, who had been sitting in the doorway between the cells, suddenly felt compelled to move to the window. Once there, he described a strong urge to shout. When he did, the cat ball lit on command, and the tension in the room noticeably lifted.
Noises and movement
Across the session, the team logged:
Two distinct thuds within the room with no obvious external cause.
At 12:16 am, two clear footsteps from inside one of the cells while all team members were still.
At 12:46 am, a series of knocks above the room, followed by more footsteps at 1:11 am and 1:14 am near the table area.
These sequences gave the impression of movement between levels, as if someone was pacing above and around the team.
Names and data
In the Guard Room, the investigative app produced a cluster of names, including Ezekial, Kevin Baker, Edmund, Ralph, David, Mr Baker and Mr Right. No direct historical link with Slough Fort has been confirmed yet, but the timing of these names with the rise in activity made them worth noting.
Taken together, the physical sensations, noises and responsive equipment made the Guard Room one of the most active spaces of the night.
Lower Magazine
Initial walkaround
On first entering the lower magazine, both Laura and Dan reported an immediate change in atmosphere. The air felt charged and static, with:
The K2 meter spiking into red, indicating strong EMF in the area
Laura sensed a figure standing at the tunnel entrance, leaning casually and watching the team - this has been picked up on previous visits by other team members. This was Laura’s first visit to Slough Fort.
During this walkaround, Laura asked a couple of direct questions and heard a clear internal response of “Yes”. She and Dan both felt strongly that they should leave the area, as if they were being pushed out.
Team A in the lower magazine
In the second half of the night, Team A focused on the lower magazine and recorded some of the most striking activity of the investigation.
EVP and interaction
Shortly after entering, the app referenced a “William”. When the team asked “Is William here?”, all three (Dan, Laura and Darren) heard an audible male voice reply “Yeah”.
This response was captured on camera from the far end of the magazine. You can hear it here: https://youtu.be/T-vlWxUY06U
Physical contact and shadows
Throughout the session:
Team members reported being touched at different times, with Darren feeling it on his arm, Jake on his back and Dan on his lower back, with no visible cause.
Several shadow figures were seen, including a clear view of a head and leg stepping back into the darkness, observed by Darren. This same shadow has been seen by different people on previous visits.
The group repeatedly heard footsteps, shuffling and bangs that seemed to move away from them whenever they approached a particular end of the magazine, creating a strong sense of being led around. This mirrored the “chase” pattern noted in earlier investigations at Slough Fort.
Around midnight the activity suddenly stopped. Laura sensed a presence emerging from the tunnel and stepping forward as if to halt communication. After a short break, the team returned to find the energy much quieter, with only minor noises.
Before leaving, Dan saw what looked like a white, round face peeking from behind a wall, which then quickly withdrew. Static camera footage from this doorway later showed a strange swooping shape moving round the bottom of the frame and retreating, with no clear physical explanation. You can see that clip here:
Team B in the lower magazine
Team B began their night in the lower magazine and also experienced frequent, seemingly responsive activity.
Key points:
Cat balls repeatedly lit on command, often directly after a question or request for confirmation.
The laser grid was seen to distort or shift when the team asked for a sign, accompanied by metallic tapping on nearby railings.
Several members felt a temperature drop, tingling or static across their bodies.
The app produced multiple names, including Mildred, Jo, Smith, Taylor, Glen, Kevin Baker, Edmund, Ralph, David, Mr Baker and Mr Right.
During the session, the team also heard:
Footsteps, shuffling and metallic tings that could not be traced to any obvious source
A burst of static over the walkie talkie
Moments of dizziness or unease, with Sam briefly losing balance and spontaneously saying the name “Gary”
Activity seemed to intensify when emotions were higher or when participants spoke directly to whatever might be present, especially during Ricky’s verbal challenge followed by an immediate cat ball activation.
Environmental factors such as aircraft noise and lingering paint fumes were noted, but could not account for the specific, timed responses.
Evidence Highlights
From the whole night, a few pieces of evidence stand out:
EVP: A clear male voice responding “Yeah” to the question “Is William here?” in the lower magazine, heard in the room and captured on camera from the opposite end.
Physical interaction: Multiple team members experiencing similar physical sensations in the same areas at the same times, which lifted when they moved away.
Visual phenomena: Shadows and fleeting figures observed by more than one person, including a head and leg stepping back into darkness and the swooping shape recorded near the doorway.
Intelligent responses: Cat balls and environmental sensors activating on request, and the laser grid appearing to distort when asked.
Consistent patterns: The repeating “chase” dynamic in the lower magazine and familiar footsteps leading investigators from one end to the other, seen across several visits.
Where possible, the team tried to replicate or explain these events through normal means. What remained was recorded as unexplained, rather than labelled as proof.
Our Interpretation Of The Activity At Slough Fort
Taking the night as a whole, Slough Fort showed signs of both intelligent and residual activity.
Intelligent responses
Direct, well timed answers to questions, such as the “Yeah” EVP after asking for William.
Cat balls and other devices lighting or reacting immediately after requests.
Changes in atmosphere and activity when specific people spoke or moved to particular spots.
Residual or cyclical patterns
Recurrent footsteps, knocks and movement sounds in the same areas, regardless of what the team were doing.
The established “chase” pattern in the lower magazine, where noises and sensations seem to draw investigators up and down the space.
During the night and the debrief, Laura also raised the possibility that elemental-type energies might be influencing at least some of what is happening here, particularly the playful, teasing behaviour reported in the lower magazine. Later research into traditional descriptions of elementals seemed to match parts of what the team had experienced. A separate article on elementals and how they might present will appear on our site for anyone who wants that background.
So, is Slough Fort haunted?
We cannot claim to have every answer, but this investigation, taken together with previous visits, suggests that Slough Fort remains an active and energetically complex location. There appear to be both intelligent and residual elements at work, with patterns that repeat across different teams and different nights.
What This Means For Future Investigations And Events
For the volunteers and teams who work with Slough Fort, the main takeaways from this investigation are:
Activity seems strongest in the lower magazine and Guard Room, with additional patterns in the courtyard and entrance areas.
Small group sizes and clear, calm questioning help in getting more structured responses and cleaner audio.
Keeping careful logs of times, conditions and team locations is vital for spotting repeated patterns across multiple visits.
For future events or investigations at Slough Fort, we would recommend:
Spending focused time in the lower magazine and Guard Room, especially in the doorway and tunnel entrance areas.
Building in quiet, low-light periods where teams simply sit, listen and observe.
Continuing to review static camera footage carefully, especially around doorways and corners where shapes have been seen pulling back.
