Newcastle town wall, Durham Tower

An almost complete example of a single-storeyed semi-circular tower. The rectangular rib-vaulted room is lit by two surviving loops (the third is now a door), and was originally entered from the intra-mural lane though this door is now blocked. Externally the tower retains traces of six sets of three oversailing corbels to support a bretasche; the parapet round its flat roof is largely missing. It is not clear how the roof of the tower was reached. Was once used as a military lock-up, and in the 19th century "as a coal and lumber room for the adjoining school".
