A 16th century, Grade II* listed building, a fine example of a 16th century gentry house and has good claim to be the birthplace of the modern Welsh language. It was at Dolbelydr that Henry Salesbury wrote his Grammatica Britannica. Dolbelydr is cared for by The Landmark Trust, a building preservation charity who let it for holidays. Full details of Dolbelydr and 189 other historic and architecturally important buildings are featured in the Landmark Trust Handbook (£10 plus P&P refundable against a booking) and on the website.
