In the central Gateway panel is a scene inside the tower mill. The upright shaft is nowhere near the centre of the floor and a pair of stones without vat, hopper and horse is being overdriven by a quant and stone nut from the overhead great spur wheel. A double-sided sign showing on one side the tower corn mill. The post mill on the sky line, described as 'typical of the 15th century,' has, however, a fantail. At that time it would have had a tail pole and would probably have been a 'sun' post mill with crosstrees at ground level or below.
Sign shows the drainage tower mill.
The pond in front is not a mill pond, but is farm pond across the road from the mill, though it is often depicted showing the reflection of the mill. The tower corn mill at the Staithe is shown with its four white sails on the horizon. The mill shown here would be one of the many drainage mills on the marshes. The derelict capless tower is shown at the top of the sign. The circular base is a millstone from the mill.
