Designed by Thomas Roderick, architect of Aberdare, and opened in 1907. Free Jacobethan style with eastern influences to the dome. Symmetrical school building: boys to the left, girls to the right. Each half designed to be self-contained - hence the lack of a main entrance. Dark, coursed and bull-nosed local stone with 'Red Wilderness' dressings. Slate roofs. Camber-headed horned sash windows with voussoirs and keystones (RAJ, RCAHMW, 2 February 2004; based on CADW list description).
