Norwich Castle

G. T. Clark, a 19th-century antiquary and engineer, described Norwich's great tower as "the most highly ornamented keep in England".[19] It was faced with Caen stone over a flint core. The keep is some 95 ft (29 m) by 90 ft (27 m) and 70 ft (21 m) high, and is of the hall-keep type, entered at first floor level through an external structure called the Bigod Tower. The exterior is decorated with blank arcading. Castle Rising is the only other comparable keep in this respect.[8] Internally, the keep has been gutted so that nothing remains of its medieval layout. The uncertainty surrounding the keep's arrangement has led to scholarly debate. What is agreed on is that it had a complex domestic arrangement, with a kitchen, chapel, a two-storey high hall, and 16 latrines.[20]
