English: The basement level of Joseph Williamson's house in Mason Street, Liverpool. The facade of the house is visible in the distance, and in the opposite direction are the remnants of window frames, which would have likely led to a garden below ground level. The partially-bricked archway leads to the 'Wine Bins' and other areas of tunnels, while the 'Banqueting Hall' lies directly beneath the camera, with the floor approximately 30ft below.
