How to explore the hidden deep end at Stirchley baths
This weekend could be great if you like exploring places you don't normally get to see. Thats because hundreds of historic buildings across the Midlands are opening their doors to the public for free.
This year Heritage Open Days are encouraging us to discover the hidden spaces in our towns and cities to learn about our past, and we sent Chris Halpin underground to find a secret swimming pool!
He's been to Stirchley Baths in South Birmingham which earlier this year became a community centre, after more than quarter of a century as risk of ruin.
