St Mary de Lode is a parish church in Gloucester adjacent to the cathedral. Some believe it was built on the site of the first Christian church in Britain. It was built over a couple of Roman buildings, one was a baths, the other was a mausoleum. Some think an early post Roman-Britan church was built on the site. The current church dates from the 11th century. The church consisted of a nave, chancel and tower.
The church was badly damaged by fire in 1190. A new chancel was built in the 13th century. The central tower is Norman though the nave was rebuilt in 1826 in the Early Gothic Revival style.
