St Mary de Lode's Church, Gloucester (Chancel Vault)

This low dark vaulted tower and chancel is a real contrast to the light airy nave leading to it...

Under the floor at the west end in front of the gallery is a trap door which when opens reveals part of a Roman Mosaic pavement ten feet down, and under-water too. This remnant on view is only part of what was discovered during excavations in the 1970s. The water level is a good indicator of the water table in predicting drought. The custodian says he has seen it completely dry.
