This is a Grade I listed building, with a twelfth century nave and thirteenth century chancel. The original west door was bricked up during the sixteenth century. On the right you can see a tower stump. The fate of the original tower is uncertain. The most common theory is that it was destroyed by the Dutch in 1667, during the second Anglo-Dutch war. An alternate theory suggests that according to the church records the building was in a parlous state in the late 17th century, and it is possibe that the tower simply collapsed. However, the Dutch navy did progress along the Thames as far as Gravesend in 1667, so it is possible that the tower was destroyed by enemy action. The stump of the tower contains the vestries. It was built by the First World War garrison of Coalhouse Fort, No.2 Company, London Electrical Engineers. The original plan was to build a complete tower commemorating the fallen in the Great War, and General Gordon of Khartoum who built the Coalhouse Fort. However this plan was never completed.
