Capel-y-Graig Unitarian Chapel was built in 1884 to the design of architect John Wills of Derby. The chapel was later rebuilt in 1906, in the Gothic style of the long-wall entry type and with an integral tower. Capel-y-Graig has snecked rock-faced stone walls with Bath stone dressings and slate roofs with fancy terracotta finales to the gables. A new detached vestry was built in 1929.
