Black and white photograph showing a sidewall and a rear wall of The Spa Theatre in Bridlington. Taken from across a promenade, it shows a white building with the sidewall on the left and the rear wall, incorporating a projected block (the original entrance), to the right. The sidewall has three main bays, with the wider central bay slightly advanced and topped by tablature spelling SPA THEATRE. A colonnade stretches along the wall at its base and entablature above some windows at second floor level continues around the rear wall. The projected block on the rear wall has a façade in three bays, modestly detailed in classical style with a segmental pediment over the centre. It has two entrance doors set in a projecting enclosed porch under a curved-fronted balcony. Another double-door entrance, possibly the stage door or get-in, is visible on the rear wall’s nearest corner.
