Dorchester Castle

Dorchester Castle was a motte and bailey castle in the market town of Dorchester, Dorset, southern England (grid reference SY692909).

Both Henry III and John spent money on the castle.

[2] It appears to have been disused from about 1290 and there are references to its stonework being reused by the Chidlock family to build Dorchester Greyfriars in 1309.

[7] However, in 1720, two underground passages were discovered while building a chapel: these once connected the castle to the town proper.

[8] The gatehouse was built in 1790 and has been designated as a Grade II listed building.
