Saturday 20th August - Sunday 30th October This month, St George’s Hall is set to launch the most exciting tour yet to hit the city and, make no mistake, this voyage is not for the faint of heart…! For the first time in over 100 years, visitors will be invited to discover the magnificent Grade I listed building’s hidden depths and unseen places - from the old rickety wooden structures of the dark corridors above The Great Hall, down to the recently discovered lost tunnel below.
