Survey of St Martin's Church by Pevsner. 'St Martin, West Stockwell Street (Now a cultural centre). The NW angle of a C12 N aisle, narrower than the present aisle, reveals a church of that date . The W tower also Norman but a little later. It was built with much use of Roman bricks, but is now in ruins and looks very picturesque with the two fine old chestnut trees at the entrance to the churchyard. The chancel follows next; early C14, as can be seen from the E window, of three lights, with ogee-reticulated tracery, the S doorway, and the PISCINA inside, both with richly crocketed ogee heads. The way in which the SEDILIA are subdivided into two seats by simply bringing down the mullion of a two light window in a double curve is also characteristic of the Dec style. But perhaps the most impressive early C14 feature is one roof truss across the chancel which possesses moulded wall posts, arched braces with elaborately foiled tracery, an embattled tie-Beam, an octagonal king-post with capital, and four-way struts. Early Perp transepts with tall windows with panel tracery, and Early Perp N and S arcades with octagonal piers and double-hollow- chamfered arches. The S porch is attributed to the early or mid C17, perhaps on the strength of the amusing side windows, with balusters instead of mullions.-FONT. Octagonal, C14, with recesses in the stone crowned by three-dimensional ogee arches bending forward on to the bowl. - (PULPIT with sections of C16 and C17 woodwork)- SCREEN. Six early C15 traceried arches below the rail.-MONUMENT. Big, heavy, Neo-Greek sarcophagus to William Sparing 1816, in the churchyard, S of the porch. <1>
