Norwich 12 is an initiative by Norwich Heritage Economic and Regeneration Trust (HEART) to develop 12 of Norwich's most iconic buildings into an integrated family of heritage attractions which act as an internationally showcase of English urban and cultural development over the last 1,000 years.
Norwich HEART initially secured £1 million from HM Treasury's Invest to Save Budget to run this pioneering heritage concept.
The 12 buildings are a collection of architecture that encompasses the Norman, medieval, Georgian, Victorian and modern eras.
Norwich Castle is a Norman building, originally built as a royal palace for William the Conqueror, at a time when most buildings were small, wooden structures. The huge stone keep was a symbol of the king's power.
The Castle mound (motte) is the largest in the country, and from the 14th to 19th century the keep was used as a county gaol.
The Castle was converted into a museum in 1894.
Most of Norwich Cathedral's Norman architecture is still intact and it forms one of the most complete examples of the Romanesque style in Europe. Like the Castle, the Cathedral's scale signified the power and permanence of the Norman invaders.
