Coordinates: 53°10′08″N 3°48′19″W / 53.168764°N 3.805229°W Maenan Hall is an Grade I-listed hall house located north west of the village of Llanddoged, Conwy, Wales. This late medieval country mansion has fine decorative plasterwork and was the home of the Kyffin family. It is currently in private ownership but the extensive gardens are open to the public on a few occasions each year.
The name Maenan means "place of the big stone" in Welsh. There have been three reasons as to why the hall was given this name: near to its current driveway there is a large outcrop of rock which was possibly a description of the hall. A large number of dolmens exist in the Conwy valley; the valley has many glacial boulders and its suggested the hall was given its current name because of the large amount of stones in the valley. In the 1841 census the house was listed as Maenan; it first became known as Meanan House by the time of the 1881 census but reverted to Maenan by 1891. Its name was recorded as Maenan Farm in the 1901 census.
The original timber frame design of the house included six bays which had a central entrance and wooden ionic portico which dated to the late 15th century. The house was the seat of the Kyffin family. In 1582 Maurice Kyffin, the High Sheriff of Caernarvonshire, altered and expanded the building; Kyffin encased the building's walls in rubble.Henry McLaren, 2nd Baron Aberconway brought Maenan Hall in late 1945 and started repairs to the building which had not been maintained for several decades. Aberconway brought the estate for his wife, Christabel, as a dower house. He died in 1953 and farmer Lewis Lloyd Williams along his family moved into the nearby Byrn Rhudd house.
