Norwich was once described as having a pub for every day of the year and a church for every Sunday. The castle is the centerpiece of Norwich, and is surrounded by a compact medieval street plan. Within the circle of river and city walls there are more than 30 churches and an Anglican cathedral. At the heart of the city is the canopied market, one of the biggest and oldest markets in England. The Norwich Museum Castle and Art Gallery sits on a hilltop overlooking Norwich. The castle ranks highly on the list of best preserved examples of Anglo-Norman military architecture. It is now home to a great museum and art gallery with diverse exhibits ranging from the Normans and Anglo Saxons to an Egyptian gallery with mummies. The art gallery houses paintings of the acclaimed 19th century Norwich School of landscape painting and the world’s largest collection of ceramic teapots. The all-glass Forum building is the most impressive one to be built in Norwich in decades, and it is home to the town’s main library, the regional BBC, and the tourist office. Here you can also find Origins, a family-focused museum that explores 2,000 years of local history. The focal point of the city is the Norwich Cathedral built in the 11th century. Its barbed spire is higher than any in England except the one in Salisbury, and the size of its cloisters is the greatest.
