This month work began on a £13.5m scheme to turn the city’s iconic keep back to its original 12th century lay-out.

The renovation will see all five levels made fully accessible for the first time, while a new medieval gallery will be installed in a partnership with the British Museum.

There will also be a new café overlooking the atrium, with an internal glass bridge into the keep, and a new shop.

Alan Waters, leader of Norwich City Council, said: “The planned changes to the keep will provide a completely new way for people to explore its history as a castle and still enjoy the collections we’ve come to know and love.”

Norwich Castle is due to reopen next month but the keep will remain shut during the work.

It is hoped the keep will reopen in 2022.
