Treowen
Treowen (or Tre-owen) is an early 17th-century house in Monmouthshire, Wales, regarded as "the most important early C17 gentry house in the county". It is located in open countryside within the parish of Wonastow, about ½ mile (1 km) north-east of the village of Dingestow, and south-west of Monmouth. It is a Grade I listed building, and, after being used as a farmhouse for three centuries, is now a conference and functions venue.
