Norwich 12 was 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 to act as an international 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 the pioneering heritage concept. The 12 buildings are a collection of architectural styles that span across Norman, medieval, Georgian, Victorian and modern eras.
