Standing beside Lambeth Palace is all that remains of St Mary-at-Lambeth church. Or, more correctly, its tower.
There has been a church on this site since before 1086, while Lambeth Palace opened in 1435.
In 1851 the church was demolished, with the exception of the tower, and rebuilt, so that more seats could be added. This Middle Ages inspired building remained in use until 1972.
At the base of the tower, is an immersion font. Archbishop of Canterbury Edward Benson (1883-1896) appointed his close friend John Reeve as the Rector of St Mary's, in 1894. Reeve commissioned this font in Benson's memory. It is one of only two known examples of an immersion font to be found in an Anglican church.
The tower is still accessible to visitors who, for a small fee, can climb the 131 steps to the roof of the tower.
