St. Andrew's Hall and the adjoining Blackfriars' Hall is a Grade I listed building in Norwich, Norfolk, dating back to the 14th century. They make up the most complete friary complex surviving in England. The complex is made up of several flint buildings. The centrepiece is St Andrew's Hall. The first Dominican Black Friars' priory was destroyed by fire and St Andrew's Hall formed the nave of the new church, completed in 1449. There is also a Blackfriars' Hall as well as a crypt, chapel and cloisters. During the Reformation, the site was saved by the City Corporation, which bought it from the king for use as a 'common hall.' Since then the complex has been used for worship, as a mint and as a workhouse. It has been used regularly for civic occasions since 1544, when the first Mayor's feast was held for the inauguration of Henry Fuller. The Norwich Triennial Festival, the third oldest in the country, began here in 1824. The Halls are now used for conferences, weddings, concerts, beer festivals and meetings. The maximum capacity is 1200 people. It is one of the Norwich 12 heritage sites.
