Hebron Welsh Independent Chapel was first built in 1804-5, enlarged in 1824, rebuilt/modified in 1879. The chapel was built in the Vernacular style, from coursed rubblestone with yellow stone dressings. The front facade had three bays, with a projecting central bay. The double arched-headed doors, with Y-tracery lights over, were topped by a palladian window, with a central arched window with Y-tracery flanked by two narrow plain panelled lights. The side bays each had a single window with Y-tracery. The hipped roof was of Welsh slate.
