History

Former stable range for the Dowlais works, built for Sir Josiah John Guest in 1820. The large first-floor rooms were used as a boys school until the Dowlais Schools were built in 1854-5. Soldiers were stationed here for several years after the Merthyr riots of 1831. The stables closed in the 1930s. The range was derelict by the 1970s and bought by the Merthyr Tydfil Heritage Trust in 1981. The interior and rear were wholly rebuilt as flats and the facade walls were also substantially rebuilt.

Exterior

Former stable range now flats, squared grey brown rubble stone with dressings in grey limestone and some renewed in tooled sandstone. Slate eaves roofs. Two-storeys with centre and end pavilions separating 9-bay ranges. The right range and upper part of left pavilion are entirely rebuilt. Originally the 2 ranges had limestone voussoirs to cambered headed lower windows and segmental headed upper windows, with small-paned glazing and stone sills. Left range had plinth with limestone coping, due to slope of site. The front wall of the right range is rebuilt with sandstone voussoirs to openings. All windows are later C20, small-paned casements with 4-pane top-light.
