History

A few features remain from a probably late C16 house - an arched fireplace and stone doorways in NW wing. Vaughan Poppy records Phillip Vaughan of Tyle-Glas who married the daughter of Lord Hereford in 1588 as the owner until 1601. House was rebuilt c 1630 creating a large E shaped building, the surviving C17 first floor windows being at a high level. This building reputedly the home of the sister of Henry Vaughan, the metaphysical poet who was born at nearby Newton. An extensive remodelling took place in 1805 with the erection of a grand Regency frontage for Admiral Sir Edward Hamilton who still owned the property at the time of the tithe 1839. Part of the Glanusk estate sale 1918. Trebinshwn has various spellings. Jones gives the provenance of the name as Pentre Sion or Tref pen Sion and traces the occupiers back to C16.
