St. Nicholas Seamen's Church (Swansea Arts Workshop)

St. Nicholas Seamen's Church, now known as Swansea Arts Workshop, is a Grade II listed building. It features a plan with an apsidal chancel, a porch, and a vestry at the angles, along with a taller single cell nave that has been subdivided. The church has a west bellcote, which is partly taken down. The exterior is constructed with rubble facings and freestone dressings, topped with tarred slate roofs. The chancel has a hipped roof, while the nave has a gable parapet with kneelers and a cut-down stack at the rear. There is a corbel table at the eaves of both the chancel and the rear nave, along with linked nailhead detailing. The rear roof features modern glazing and a box dormer. The elevation facing Gloucester Place has replaced windows and a modern wide entry. The north end has various additions, including a brick arched doorway, a gabled three-light dormer with a diamond tympanum under cusped bargeboards, and cut-down buttresses from the former bellcote.

Inside, the church has been largely modernized, retaining only the boarded, pointed nave ceiling and a round chancel arch with chamfered imposts.
