St Mary's, Deerhurst is certainly the most imposing, enigmatic and controversial Anglo-Saxon building in the county, and perhaps the whole country. It retains features from several periods of Anglo-Saxon building, covering the period (depending on which version of its history you prefer) from the 7thc to the 11thc. Putting the standing evidence together into a believable building sequence is by no means straightforward. The general reader who has prepared for a visit to the church might well be surprised to find any post-Conquest material there at all, but the interior is dominated by the late-12thc nave arcades that will be the main subject of this report.
An oversimplified version of the story is that the earliest church, predating the first mention of a monastery here in 804 might have been a rectangular box with a W porch. This church was greatly enlarged in a second phase of building, usually assumed to correspond to the late-10thc reform movement. Porticus were added alongside the nave, and a polygonal apse was added at the E end. The nave was raised at the same time to its present height of approximately 12m, and a chancel was carved out of the rectangular nave by the insertion of a cross wall. Around this time too, the W porch was given extra stioreys to convert it into a tower porch (although this may have been done in several phases). After the Conquest - perhaps as late as 1190 - the porticus flanking the nave were replaced by aisles with 3-bay arcades. The S aisle was later (but still in the 12thc) fitted with transverse arches carried on responds abutting the nave arcade piers. The plan included here, displayed inside the church, shows one interpretation of the building phases.
What survives, therefore, is a church with a chancel, aisled nave and a W tower porch. The aisles extend W alongside the tower, and a passage linking them, W of the central vessel, forms a kind of W transept. Remains of 12thc work survive here, notably in a section of foliate stringcourse of the W wall of the passage. The W end of the N aisle now houses Deerhurst's famous font; presented as a work of 9thc art in its own right, dramatically lit from below. This report is provisional, as access to the upper levels of the tower was not available at the time of the visit.
