Coed Coch, in Dolwen, Denbighshire, Wales, is a large 19th-century mansion in the neoclassical style, designed by the architect Henry Hakewill. The building is Grade II* listed, as is its 18th- and 19th-century parkland. The mansion is of ashlar, originally with two matching, three-bay elevations. At a diagonal, was a "remarkable" Greek Doric portico, with pediment. This was removed in the early 20th century. The main elliptical staircase remains within a rotunda and lit by a small lantern dome. The original parkland "survives in its entirety".
