St Ninian's Episcopal Church, Whitepark Road, Castle Douglas

St Ninian's Episcopal Church, located on Whitepark Road in Castle Douglas, was designed by architect E B Lamb in 1864. This distinctive Gothic church features a chunky polychrome granite exterior. It consists of a rectangular hall with a nave and a narrower, lower chancel to the east. A tower, added in 1875, is positioned at the northeast re-entrant angle, while a porch to the southwest and a vestry to the southeast are both low gabled structures.

The church is constructed from bull-faced coursed rubble with granite margins, and the basecourse is stepped granite. The window margins are bull-faced to the wall-face, with polished inner arrisses. The pointed-arch entrance to the porch is complemented by trefoil-headed lancets, arranged either singly or in groups of two by two at the west gable, or five at the east gable. Granite corbels at the eaves support a polished granite blocking course and granite skews. The roofs are covered with slate, featuring alternate rows of fish-scale slates.

The tower is buttressed and divided into three stages, with a corbelled third stage that includes trefoiled lights in roundels and a corbelled parapet that steps up at the angles.

Inside, the church features a pointed chancel-arch supported on label-stops and corbels. An octagonal timber pulpit is present, and the roof ribs are supported on stone corbels. The interior also includes stained glass by Taylor. Surrounding the churchyard are rubble walls topped with granite coping and caps on the gatepiers.
