The guildhall is the remains of the house of a prosperous Blakeney merchant, with a fine 15th century brick-vaulted undercroft. It is filled with stories of smuggling and secret passageways.
The main building has gone, but there are remains of the 14th century undercroft, this was probably the basement of the merchant's house and was used for the storage of cargo and also at some time as a mortuary for drowned sailors.
The Guildhall is in an alley just off the quay and is owned by National Heritage. The property is managed by Blakeney Parish Council and is open all year 7 days a week. Opening time is stated as "any reasonable time", and entry is free.
