Birmingham's imposing Curzon Street Station opened its doors to invited guests for the launch of the Hidden Spaces photography exhibition on Friday evening.

The Grade I listed former passenger terminus, recognised as the world's oldest surviving piece of monumental railway architecture, is hosting the photography exhibition, a joint venture between Associated Architects, the Birmingham Post and RIBA.

The Post's stunning photographs reveal the unknown stories behind some of the city's most recognisable buildings. Buildings featured include the Council House, Assay Office, Perrott's Folly, BT's Anchor Exchange tunnels and Curzon Street Station itself.

The Lord Mayor of Birmingham, Coun Shafique Shah, joined more than 100 other guests at the Hidden Spaces launch event.

Birmingham Post editor, Stacey Barnfield, Anthony Clerici from RIBA and Matthew Goer from Associated Architects welcomed guests with speeches about the Hidden Spaces project.

Hidden Spaces is open daily from 10am to 3pm until Sunday, June 29, at Curzon Street Station. The images will then be displayed at the Library of Birmingham.
