Elim Pentecostal Church (Formerly Greenside Mission Chapel), Greenside Street

This is a late 19th-century Elim Pentecostal Church, formerly known as Greenside Mission Chapel, built in 1873 by John Melvin (senior). It is a tall, single-story building with an attic, consisting of a six-bay Gothic chapel and a three-stage square tower to the left. The chapel is constructed of stugged, squared, and snecked rubble stone with ashlar dressings, featuring long and short quoins. A base course and moulded cill course are present at ground floor level, the cill having a square stop to the east, and linking to a stepped hoodmoulding above the door on the north elevation. Openings are chamfered, and have projecting cills, with predominantly shouldered arched window surrounds. Some ground floor windows also incorporate stepped hoodmoulding. Gabled dormers break the eaves, incorporating louvered trefoil insets and Latin cross finials to the two outer right bays.

The north (Greenside Street) elevation features a prominent, off-centre gable with stepped coping, housing a shouldered arched bipartite window with a chamfered mullion, flanked by shorter pointed arched windows. Blind roundels separate the windows, all set within an arched shallow recess; a louvered quatrefoil carving sits at the gable apex. The three-stage tower to the outer left is divided by moulded string courses, featuring a shouldered arched doorway with a stepped hoodmoulding, and a plaque bearing the inscription 'Greenside Mission Chapel 1873'. The second stage has round arched bipartite windows with lugs, and the third stage has tripartite round-arched louvered windows with a projecting cill and a bracketed corniced eaves course. The roof is a pyramidal fish scale and diaper pattern slate roof with bellcast eaves and brattishing to a small platform.

The east elevation has three round arched windows, with a louvered roundel above, and square finials to the apex with iron brattishing set between them. The west elevation features a pair of shouldered arched blind windows at attic level, with a louvered roundel above. A later, single-story, monopitched concrete block extension is also present. The south elevation is similar to the north and abuts the retaining wall of Alloa Old Kirkyard (listed separately).

The church incorporates a variety of non-traditional windows and 2-leaf timber doors. The roof is covered with grey slates, with dormered and louvered vents close to the ridge of the main hall. Details include coped ashlar skews with stepped skewputt, and coped ashlar stacks.

Inside, the church has been comprehensively remodelled, including the replacement of the gallery front. A stone stair with well-detailed cast-iron balusters and a timber handrail leads to the tower.
