A unique photography exhibition will reveal some of the lost traces of Birmingham’s rich architectural heritage.

Set in the magnificent backdrop of the former of Birmingham Municipal Bank on Broad Street, the Hidden Spaces exhibition – a joint project between the Birmingham Post and Associated Architects – will feature a collection of unique photography and video footage showcasing 25 of the city’s finest gems, from secret underground tunnels to grand Victorian banqueting suites.

The exhibition is the culmination of the Hidden Spaces ‘Unlocked 2015’ programme of events that have taken place throughout June as part of the Royal Institute of British Architects (RIBA) Love Architecture Festival.

From fascinating talks, to open buildings and walking tours, the diverse range of events aims to reconnect people of all ages with the city’s rich heritage.

Steve Townsend, co-creator of Birmingham’s Hidden Spaces and architect at Associated Architects, said: “The many fascinating spaces behind the facades of Birmingham, however elaborate or unusual, all have a story to tell. They connect us in some way with the city’s history, a forgotten time or a significant moment that shaped the city of today. They reveal something important about Birmingham and what it means to be a Brummie.

“The exhibition at the Municipal Bank offers a rare opportunity for the public to explore one of Birmingham’s finest historic buildings.

“The stunning collection of photographs and video footage on display will uncover some of the remaining traces of the city’s impressive heritage and we hope it will get people excited about Birmingham and its many achievements.”

Birmingham Post editor Stacey Barnfield said: “The Hidden Spaces project continues to grow and grow as it captures the imagination of the Birmingham public.

“Building on the success of the photographic supplements, the Unlocked events and Municipal Bank exhibition are new ways of getting people engaged in architecture as huge regeneration schemes change the city’s skyline.”

The exhibition is free of charge and is open to the public daily from June 20-28, 10am-4pm at the former Municipal Bank on Broad Street, Birmingham.
