From the Wikipedia article
Penarth Fawr (also spelled Pennarth and historically Pennardd) is a hall house in the community of Llanystumdwy, Gwynedd, Wales. The west wing of Penarth Fawr is significant as a surviving example of a medieval hall house. It was built c. 1476 by Hywel ap Madog, a member of a prominent Eifionydd family, and originally consisted of a three-bay hall with a one-bay service end to the south and a parlour wing to the north. It was later altered, but restored to approximately its medieval appearance in 1937; the intact roof structure, which includes a spere truss, is particularly notable. The hall is described as "one of the most important medieval gentry houses to survive in Wales" by Cadw, the historic environment service of the Welsh Government, and as "an important medieval hall house" in the Buildings of Wales series. It is a grade I listed building and a scheduled monument. The hall passed into state care in 1949 and is now managed by Cadw. There is a seventeenth-century wing attached to the south-east of the building, which is a private dwelling. A parlour wing of the same date to the north of the hall, which replaced its medieval predecessor, was demolished c. 1843. The seventeenth-century wing and nearby stables are each listed at grade II.

Background
History
The first mention of Penarth Fawr is in the Record of Caernarfon, a mid-fourteenth century survey of tenants and their land in North Wales. Penarth was a free township, meaning its tenants held their lands directly from the Crown, and it is likely that there was a house on the site of the present hall. The first recorded owner of the site is Madog ap Hywel (d. 1461), who with his kin claimed descent from Collwyn ap Tagno, a twelfth-century prince. The fourteenth and fifteenth century history of Eifionydd (the commote within which Penarth lies) is characterised by often violent feuds between those families that claimed descent from Collwyn and those that claimed descent from Owain Gwynedd,…
Description
Pennarth Fawr is located on a minor road off the A497, south of Llanarmon, south-west of Chwilog, and north-east of Abererch. The surviving fifteenth-century house is a rectangle four bays long, with the long sides running north-south. The northern two bays contained the hall, the third bay the screens passage, and the southern bay the service rooms. A seventeenth-century extension is attached at right angles to the southern half of the east wall of the hall and extends east. Both parts of the house are constructed of rubble stone under slate roofs, however the hall roof was originally of stone. The west wall of the hall contains the majority of the externally visible medieval fabric,…
