Royalists stationed troops in St Peter's Church during the Siege of Reading in 1643, and situated a cannon on top of the church tower. The Parliamentarians used artillery to destroy the tower. The church itself was also damaged in the process.[3][4][5] The tower was initially replaced with a wooden tower. A south aisle was added in 1878, along with the present tower. It has eight bells, the oldest of which dates to 1637. Rectorial rights were restored in 1916.[2]
