Oswald's Temple, Auchincruive

Oswald's Temple is a two-storey, circular tea house designed by Robert Adam in 1778. Constructed from coursed sandstone ashlar, it stands within the Auchincruive Estate, which has a history stretching back to the 13th century, passing through various owners before being acquired by Richard Oswald in 1764. The estate remained in the Oswald family until 1925, when it was gifted to the West of Scotland Agricultural College and remains under their ownership. The surrounding formal landscape, originally dating from the 18th century, has been significantly altered and remodelled, with Oswald’s Temple being one of the few surviving features of the original design, despite suffering from subsidence due to mining. The temple is believed to have been inspired by the mausoleum of the Emperor Theodoric in Ravenna, which Adam visited in 1755; it is considered an exceptionally fine example of its type.

The building features a ground floor bastion with four engaged towers, each terminating in crenellated parapets (with some sections missing). The ground floor originally had round-arched doorways with radial voussoirs, now bricked up. The upper floor contains a circular tea room set back from the parapets and defined by a twelve-bay round-arched arcade. Most arches are blind, however there are four small-pane timber-framed window and door openings above the original ground floor entrances. Tooled stone grotesque paterae are centred on each arch. A corbelled machicolated cornice sits below the crenellated parapet, which tops the structure, and the roof is conical with a spherical finial.

Originally, a servants' room occupied the lower floor, accessible via a circular corridor. The corridor was originally entered through the four round arched doorways. The upper floor was the tea room, with a balcony overlooking the corridor. While Robert Adam's drawings depict an external double staircase leading to the balcony, this was never built, and a simpler staircase now leads from within the corridor. Oswald's Temple is part of a group listing which includes East Lodge, Gibbsyard, Hanging Garden, Ice House, Oswald Hall, Walled Garden, West Lodge and Wilson Hall.
