A new exhibition featuring some of Birmingham's 'Hidden Spaces' has now opened to the public.

The former Municipal Bank building is playing host to the displays which feature 25 of the city's most fascinating buildings - from underground tunnels to banqueting halls.

Around 150 people packed into the former bank in Broad Street for a special launch event and the free exhibition will run from 10am to 4pm until June 28.

Hidden Spaces is a joint project between the Birmingham Post and Associated Architects and the exhibition is the culmination of the 'Unlocked 2015' programme of events that have taken place throughout June as part of the Royal Institute of British Architects (RIBA) 'Love Architecture' festival.

The programme has included talks, open buildings and walking tours, taking in the diverse range of rich architecture across the city which the public otherwise would not normally get to see and experience.

Steve Townsend, co-creator of Birmingham's Hidden Spaces and architect at Associated Architects, said: "The many fascinating spaces behind the façades 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."
