Old Church Of St Pancras

The Old Church of St Pancras is a church with a core dating to the 11th century, with later medieval additions. It was substantially rebuilt and enlarged between 1847 and 1848 by A.D. Gough and R.L. Roumieu, who extended the nave westward, removed the original south porch and west tower, replacing them with a new vestry to the north and a south tower. Further restoration work was undertaken in 1871 and 1888 by A.W. Blomfield, who remodelled the building in a "Norman" style. Subsequent restorations occurred around 1925 and during 1979-80 by Erith and Terry. The church is constructed of roughly dressed rubble with stone dressings and a flint facade, featuring pantiled and slated roofs.

The church has a rectangular plan without aisles. The exterior displays a nave with five windows, plus a three-window 19th-century extension, and a three-window chancel. A western porch, featuring carving in a 19th-century Romanesque style, is flanked by round-arched lancet windows with hoodmoulds, label stops forming strings that continue around the nave to match similar windows. A continuous sill string is also present. Above the porch is a traceried oculus. The north and south elevations of the 19th-century extension feature a Lombard frieze at eaves level. The chancel retains some Romanesque details in its north and south doorways and in part of a 13th-century lancet window. A square-headed east window with four segmental-arched lights is set within a slightly projecting gabled bay. The south tower is in three stages, with setback buttresses flanking a round-arched lancet. It includes a round arched recess with a clock above two arches to a blind arcading, and a half-timbered belfry with louvred panels and a tiled roof with projecting eaves.

The interior, which was not inspected for the record, is noted to contain some monuments from the 16th to 19th centuries and a 6th-century altar stone.

Historically, this church is one of the oldest in London. After the construction of St Pancras (New) Church in 1822, the old church served as a chapel of ease, but was reinstated as a parish church in 1863.
