From British History Online: "The church of St Mary the Virgin is cruciform with nave, crossing, and transepts dating from the early 13th century. The north doorway and square font of purbeck marble are of the same period. The nave windows were apparently inserted in the 14th century. Later in the same century the chancel was rebuilt on a grand scale. It is of ashlar masonry externally and on both north and south sides has three uniform windows with reticulated tracery. Two of these contain original stained glass. The large east window has interlacing tracery of the same date. The two upper stages of the tower were added, or rebuilt, together with the vault above the crossing about the middle of the 15th century. At the same time the south wall of the south transept was rebuilt, and the north wall of the north transept repaired and a new window inserted. An octagonal stair turret in the angle between the nave and north transept is surmounted by a conical roof below the level of the belfry and is connected to the tower by a short passage. Much restoration was carried out during the later 19th century under the direction of William Butterfield."
My camera battery died the first time I started to photograph the interior of the church (August 2005): so more pictures -- of both the church and the surrounding Dinton Park -- were posted in March 2006.
