Castle Craftsmen Revive Historic Library Windows

Artisans with a history of restoring iconic landmarks like Windsor Castle and the Tower of London are now applying their craft to a significant Northamptonshire building. Tom and George Bayliss, specialists in stained glass restoration, are undertaking the task of replacing over 40 historic windows at Kettering Library and Art Gallery, known as Cornerstone. This Grade-II listed public building is undergoing a substantial £7 million renovation project.

The damage, caused by heavy rains in 2023, necessitated extensive repairs, including a complete roof overhaul using local Collyweston slate tiles. North Northamptonshire Council highlighted the project as a testament to the "skill and expertise" involved. The library has been temporarily relocated, and the gallery and museum have remained closed since the incident.
