Lost Houses

Moses Griffith, 1780s

A Complete List of Lost Welsh Country Houses

CURRENT TOTAL: 390

Following the model set by www.lostheritage.org.uk, all of the Welsh country houses listed below have been demolished or severely reduced in size. Ruins will be treated separately on this website. The list has been compiled from several sources, including Thomas Lloyd’s Lost Houses of Wales; the Royal Commission Inventories and my own PhD research.

If you have any images of the houses listed,  or can provide any further information please contact me.

Reason For Loss (As defined by Matthew Beckett

  • B = house destroyed by fire; where B is followed by a D, that denotes when the house was finally demolished
  • N = house demolished and replaced by a new house
  • P = a significant part of the house has been demolished
  • Pr = where the house was partially rebuilt
  • S = it is a shell or ruins
  • A = abandoned
  • Su = surplus to requirements (ie. family had other houses or was no longer required by owners (the government etc))
  • D = date of final demolition – usually following partial demolition or fire
  • Du = urban development (replaced by housing estate, hospital, school)
  • Di = industrial development (replaced or blighted by industrial works, coal mining)
  • De = derelict (ie. had fallen into such a state of disrepair that there was either not the will or financial means to repair it)
  • Dw = wartime damage (either enemy action or through requisition) too severe to be economically repaired
  • Iw = insufficient wealth to maintain house – sometimes linked to conversion of stables to replace main house
  • Pr = partially restored
