York Historic Environment Record

¶Tower 7 (NG 60015129. Pl. 20; Fig. next), probably that called 'Sadlertower' in 1380 and 1403, is of mid 13th-century type and probably one of the earliest towers on the wall. It is D-shaped and originally had an open gorge. The inside has three recesses from which the cruciform arrow slits opened. The N.W. recess has been converted into a fireplace and the arrow slit has been blocked; the brick-lined chimney must once have projected above the platform. The doorway in the wall inserted across the gorge has a shouldered lintel. The room is roofed with a segmental stone vault which cuts off the top of the central arrow slit though sloping upwards towards the rear.

The wall near Tower 7 shows a curious technique of rebuilding, also found opposite Jewbury, with rows of small stones between large ashlar blocks. In this part there is also a good example of a stone shattered by cannon shot
