A new documentary narrated by Sir Stephen Fry has charted the ambitious multi-million pound transformation of Norwich Castle’s medieval Keep.

Norwich Castle: Rebuilding History, produced by Norwich-based independent firm Eye Film, was filmed over eight years.

The public premiere at Cinema City coincided with the Castle’s reopening to the public on 7 August. It will be broadcast nationally later this month.

The film offers rare behind-the-scenes access to the conservation teams, architects and engineers tasked with restoring the Norman landmark.

Every stage of the project is captured, from early design concepts to complex construction work inside the Grade 1-listed monument.

Fry’s narration is warm and authoritative, reflecting his Norwich roots. He provides historical context ranging from the Norman Conquest to the Castle’s later use as a prison.

The production combines sweeping aerial views of the city with detailed interior shots and time-lapse sequences, illustrating the building’s transformation.

Curators say the project has created new learning spaces, lifts to the battlements and improved visitor accessibility.

Eye Film’s Charlie Gauvain said the company hoped to tell more local heritage stories: “There are such incredible things happening on our doorstep that people don’t know about.”
