The multi-million pound revamp of Norwich Castle's keep is coming on apace, with 100 tonnes of steel and timber helping reinstate floor levels the landmark building would have had in Norman times.

As these pictures show, steel beams and timber joists have been carefully put into place, to serve as the foundations of new floor levels which will better show how the Grade I listed bulding looked in the 12th century.

The best part of £15m of National Heritage Lottery money is being spent on the ambitious Royal Palace Reborn project, with work having started in August 2020.

The aim is to better tell the story of the keep and the other remarkable aspects of the castle - which has also served as a gaol and prison.

Over the summer, 100 tonnes of steel and timber were hoisted up to the castle by the enormous tower crane which looms above the building.

Custom-made steel beams were taken into the keep by contractors Morgan Sindall, with specialised spider cranes used to lift them into place and to knit them together.

Timber joists have now been added and the recreated original floor levels, from 1121, when King Henry I visited the castle, are now taking shape.

The floor of the space which will become the new medieval gallery, which is being created in partnership with the British Museum, is also taking shape.

Hannah Jackson, project manager for Norfolk Museums Service, said: "When we are done, visitors will step into the castle and experience what it would have been like when it was first constructed as a royal palace.

"It will give a sense of what it was like when Henry I visited in the 1120s."

When complete in 2024, a new glass bridge and lift will enable access to all floors of the castle, including the battlements.

Changes to the entrance will mean visitors can instantly see the walls of the keep - which have, for years, been hidden from view.

New toilets - including a Changing Places accessible toilet - have been installed, while work will also see a new shop, restaurant and learning spaces.
