St Peter's Chapel
The Chapel of St. Peter. Built by Roger Mortimer (d. 1330) to celebrate his escape from the Tower of London on St. Peter's Day, 29 June, 1324.
In 1328 Mortimer assigned a rent of £6 13s 4d to two chaplains to celebrate daily services here 'for the souls of the King, Queens Isabel and Phillipa, Henry Bishop of Lincoln, the said Roger and Joan his wife'. The Decorated style with 'Y' tracery is the most obvious remnant of the original Chapel.
The building was much altered about 1570, when a floor was inserted and the upper room was used as a courthouse, with 'two offices under the same for keping of the Recordes'.
Three Elizabethan style doorways can be detected, one of them on the upper floor where it was reached by an outside staircase.
The picture shows the curtain wall and inside the remains of St Peter's Chapel.
