Tŷ Mawr, Castle Caereinion

Tŷ Mawr is a Grade I-listed timber framed house in the township of Trefnant in the historic parish of Castle Caereinion, Montgomeryshire, Wales. Originally occupied by the Lloyd family, descendants of Alo ap Rhiwallon who had settled in Trefnant in the 13th century, the house was re-discovered in 1971 and fully restored to its late 17th-century appearance in 1997–8.
