The ground floor room is the largest of the three rooms with a very lofty ceiling. The walls are mostly red brick with shoulder high panel’s capped by a wide dado rail. At one end a short flight of stairs leads to the Mayor’s Parlour, on the opposite side there is an entrance to the truly unique brick built winding stairway, set in a defensive tower, which extends the full height of the Moot Hall.
The stairway was closed off in the 19th Century, which has preserved the intricate Flemish craftman’s brickwork. The main room has seen serice as the Town’s first Police Station, hence the grill in the main door. The number of people permitted is 45, though not all seated. At the back of the room a door leads to the prison cell and exercise yard.
