History

Upnor Castle is a Grade I Elizabethan artillery fort built in 1559-67 and expanded in 1599-1601 to protect ships at Chatham. The Dutch fleet passed it during the 1667 raid; the castle was subsequently adapted for storing naval gunpowder and later used as an ordnance laboratory.

Reported activity

A local paranormal archive records visitors mistaking a uniformed figure for a costumed interpreter. It also reproduces details from an early-1996 Chatham Standard report in which security staff described repeated alarm call-outs and doors found unlocked after the site had been secured. These are reported experiences, not evidence of a supernatural cause.

KASE perspective

KASE has not investigated Upnor Castle. The newspaper trail and named custodian recollections justify a documented-report classification, but the surviving account is secondary and should not be presented as proof. Any future investigation would require explicit site permission.

Visiting responsibly

English Heritage currently advertises guided tours on the last Sunday of each month until October, with separate community and heritage open days. Check the official page before travelling; normal admission does not permit an investigation or after-hours access. Check the venue or landowner's current information before travelling, respect closures and private property, and never enter unsafe or restricted areas.
