As consultants devise ways to redevelop Brackley’s Georgian Town Hall, the building will be part of a nationwide Heritage Open Days (HOD) initiative.
Backed by HOD patron Loyd Grossman the day be a chance to see the hidden secrets of the familiar landmark.
There will be a rare chance to climb the tower and marvel at the technology of the 130-year-old town clock, or explore the dusty attic.
The free event takes place on the Saturday, September 14, and Sunday 15.
Renowned Brackley historian, Professor John Clarke will also be giving a seminar about Brackley on the Saturday.
Mr Grossman said: “We all think we know the area where we live, but for four days in September, Heritage Open Days offers the chance to see places in a new light. Buildings open up, doors are unlocked, secrets revealed. It’s a fantastic free day out for all the family, and a chance to learn about the undiscovered heritage on all our doorsteps.”
This Wren-inspired Grade II* Listed building at the heart of Brackley town centre, has had an important role in the town’s heritage for over 300 years.
Brackley Town Council is currently awaiting proposals from Ingham Pinnock Associates on the building’s future.
Brackley Mayor Peter Rawlinson said the Town Hall is a focal point for the town and an important heritage asset.
He added: “We would encourage the community to visit the Hall as part of the weekend to learn more about its history and future.”
