The grandest example of Norman architecture in Norwich has a towering 315-foot spire and the second-largest monastic cloisters in Britain (only Salisbury's are bigger). The cathedral was begun in 1096 by Herbert de Losinga, who had come from Normandy in 1091 to be its first bishop; his splendid tomb is by the high altar. The remarkable length of the nave is immediately impressive; the similarly striking height of the vaulted ceiling makes it a strain to study the delightful colored bosses, which illustrate Bible stories with great vigor and detail (binoculars are handy). The grave of Norfolk-born nurse Edith Cavell, a British World War I heroine shot by the Germans in 1915, is at the eastern end. There's also a medieval-style herb garden, a Japanese garden, a restaurant, and a coffee shop. Guided tours are run Monday to Saturday at 11, noon, 1, 2, and 3. The Cathedral Close is one of the most idyllic places in Norwich. Keep an eye out for peregrine falcons; they nest in the spire. Past the mixture of medieval and Georgian houses, a path leads down to the ancient water gate, Pulls Ferry.
