St Columba's Parish Church, 1 Greenfield Place, Lerwick

St Columba's Parish Church, built between 1825 and 1829 by James Milne of Edinburgh, with additions made in 1895 by John M Aitken, is a two-story, symmetrical hall church of rectangular plan situated at 1 Greenfield Place, Lerwick. The church’s design is austere and classical.

The church is constructed of droved sandstone ashlar to the front, with stugged and snecked sandstone to the sides and rear, featuring droved ashlar margins around windows and corners. The front elevation incorporates a base course, a band course at the first floor level, and an eaves cornice. Projecting cills are present at the windows. The wallhead is finished with stugged and coped sandstone stacks flanking the apse.

The north (principal) elevation is symmetrical, with regularly spaced windows and full-width ashlar steps leading to a pair of six-panel entrance doors with a ten-pane fanlight above, set within architraved openings. First-floor windows are similarly architraved. The west and east elevations mirror each other in their fenestration, with the west elevation grouping four bays slightly to the right. The south (rear) elevation features a projecting apse with a curved wall and round-arched windows. Flanking single-story wings, originally a session room and vestry, extend from the apse.

The church has timber sash and case windows, predominantly 36-pane at ground level, 24 and 20-pane at the first floor, and 8 and 12-pane to the vestry and session rooms. Stained glass windows depicting Christ are incorporated into the apse. The purple-grey slate roof is piended, with a curved pitch to the apse, and a profiled gutter at the eaves.

Inside, a flagged entrance vestibule leads to symmetrical gallery stairs with timber handrails. Throughout the church are vertically-boarded timber wainscoting and a plastered, corniced ceiling. Reeded architraves surround the entrance doors and a six-panel door to the hall. The main hall features vertically-boarded wainscoting, a plaster cornice, and a ceiling with simple strapwork. A U-plan timber gallery supported by fluted Corinthianesque cast-iron columns runs around the hall. The pews are timber with flush-beaded panelling, both within the hall and on the gallery. A three-centred arch on the south wall leads to the apse, which contains a timber pulpit, communion table, and font, all dating back to 1895. The font is made of white Caen stone, featuring an octagonal bowl with carved quatrefoils supported on red marble columns with decorative capitals. An organ from Bryceson Bros & Co, originally built in 1871 and enlarged in 1895, occupies the centre of the south wall of the apse, with stencilled pipes and a panelled case, flanked by vertically-boarded wainscoting with a panelled frieze, pilastered blind arcading with stained glass windows, a plaster cornice, and a coffered dome covering a skylight. Four-panel timber doors provide access to the vestry and session room.

Boundary walls of random rubble with a stugged ashlar cope run along the south and east sides, retaining the ground to the west, returning at the north, and terminating with a wrought-iron finialled gate that matches the gate to the east.
