Heritage Open Day: The collections of Norwich Printing Museum on display on National Trust's Blickling Estate, demonstrate the connections between Norwich, its people and culture, and the printers and industry of the nation, continent and beyond! Printing has shaped the world, spreading by diverse ROUTES from China in the seventh century through Asia, Africa and Europe to the Americas and the world. The Norwich Printing Museum reflects the European phase of that history, from the late middle ages to the present day. It was largely built up by Peter Jarrold via his NETWORK of friends and colleagues in the printing industry over forty years.
