A. D. Bayne, A Comprehensive History of Norwich
“ High over the centre of the old city, over all its churches, and towers, and streets, rises the Norman Castle, frowning in feudal grandeur over the whole district. It stands on the summit of a mound or hill, steep on all sides, which appears to be chiefly the work of nature, with additions by human labour. The embattled quadrangular keep, in its restored state, retaining all the details of architectural decoration peculiar to the Norman style, presents a faithful image, though without the grey antiquity, of its original exterior, and is a noble striking object from whatsoever point it is seen. ”
