Ruperra Castle

Ruperra Castle or Rhiwperra Castle is a Grade II* Listed building and Scheduled Ancient Monument in Lower Machen in the county borough of Caerphilly, Wales. Built in 1626, the Castle is ruined as of 2023. Its grounds are listed on the Cadw/ICOMOS Register of Parks and Gardens of Special Historic Interest in Wales.

Built in 1626 by Sir Thomas Morgan, Steward to the Earl of Pembroke, it was one of the first of the ‘mock’ castles in Wales. King Charles I spent two nights at Ruperra Castle in 1645, shortly after the Battle of Naseby. Consequently, the royal coat of arms was added to the decoration on the South Porch, and the present public footpath from Rudry to the castle is still known as “King’s Drive.”
