St Peter's Roman Catholic Church, Durie Street, Leven

St Peter's Roman Catholic Church, located on Durie Street in Leven, was designed by Robert Baldie of Glasgow and built in 1870. A session house was added in 1902. The church is a simple, rectangular-plan, aisless structure with a prominent gable front, an octagonal-spired tower, and a five-bay nave. It is constructed of stugged squared and snecked rubble stone, with droved ashlar dressings. Base and string courses are visible on the narthex, and there is an eaves cornice around the building. The buttresses are two-stage and saw-tooth coped.

The west elevation is the principal facade and features four steps leading to the centre bay, with low flanking dies incorporated into the base course. A deeply moulded doorcase contains a paired nookshaft and a hoodmould that extends over small flanking windows, a broad two-leaf boarded timber door, a fanlight, and decorative ironwork hinges. Above the door is a four-light traceried window with a hoodmould and decorative label-stops. Buttresses flank the west elevation; the one on the right abuts the tower. To the left of centre is a lancet window under a continuous hoodmould, with a buttressed outer left angle.

The three-stage tower is buttressed, with a bipartite window below an arrowslit and a monogrammed quatrefoil 'JSH' on the first stage west side. A similar detail is present on the south side, but with a dated quatrefoil. The outer angles flanking the quatrefoils reduce to an octagonal second stage belfry with hoodmoulded louvered openings. Above that is an octagonal steeple with banded detail and a decorative cast-iron finial.

The south elevation is simple, with a five-bay nave and a window in each bay. Two diminutive gablet-type roof ventilators are also present. The tower stands on the outer left.

The north elevation is similar to the south, but features a slightly projecting gabled stair tower on the outer right, with a lancet window on the ground floor and a bipartite window above.

The east elevation is almost full-width, with a low, gabled bay projecting at ground level and a raised centre tripartite window in the gablehead.

The windows are diamond-pattern leaded glass, with multi-pane glazing featuring decoratively astragalled margins and tracery on the west side. Coloured glass is used on the east side. The roof is covered in grey slates, with a coped ashlar gablehead stack and ashlar-coped skews featuring gablet skewputts.

The interior of the church is galleried, with fixed timber pews, boarded dadoes, and a panelled gallery supported by cast-iron columns with stiff-leaf capitals. A ribbed ceiling and plain cornices are also present. Carved Stations of the Cross are featured, along with a stained-glass memorial window to Rev John S Hyslop, depicting St John (1901), and flanking World War I memorial lights depicting Sts Peter and James (1922).
