  Location of Perth-hir House in Monmouthshire | |
Perth-hir House, Rockfield, Monmouthshire, Wales, was a major residence of the Herbert family. It stood at a bend of the River Monnow, to the north-west of the village. At its height in the 16th century, the mansion, entered by two drawbridges over a moat, comprised a great hall and a number of secondary structures. Subsequently in the ownership of the Powells, and then the Lorimers, the house became a centre of Catholic recusancy following the English Reformation. By the 19th century, the house had declined to the status of a farmhouse and it was largely demolished in around 1830. Its ruins, and the site which contains considerable remnants of a Tudor garden, are a scheduled monument.
