Ruins of Llantrithyd Place

The ruins of Llantrithyd Place are the remains of a house that originally featured a double pile main block with adjoining wings to the southeast and southwest. The structure was two storeys high with attics. The hall was flanked by a parlour crosswing on the southwest and a kitchen crosswing on the southeast. In the 17th century, a well stair and parlour block were added to the north of the hall, creating a double pile plan. The house was constructed from local limestone, with sandstone used for the window details.

Currently, the hall lacks many external features, as both gable end walls have collapsed. The southern elevation still stands at full height and has three aligned openings. The southeast wing has no surviving structure, only its foundations remain. The western elevation shows remnants of a two-storey porch. The northwest wing's western elevation stands to full height and is lit by a three-light mullion window on the second floor. The northern elevation has four large empty openings on the ground floor, with two surviving four-light mullioned windows on the first floor. The eastern elevation's northern end remains at full height, featuring four staggered openings. The attic light still retains its mullion and transom beneath a relieving arch.

To the south of the house, there are remnants of ruined outbuildings along with 17th-century garden features. To the northeast lies the walled enclosure of Llantrithyd Park.
