Glandyfi Castle is a Grade II listed Regency Gothic castle built around 1819 for George Jeffreys, a barrister and High Sheriff of Cardiganshire, commanding a prominent position overlooking the Dyfi estuary in Ceredigion, Wales. Nestled within 40 acres of woodland between Machynlleth and Aberystwyth, the castle accommodates up to 22 guests across 11 bedrooms, functioning as an exclusive-use self-catering venue for extended stays. The property serves multiple purposes including weddings and corporate events, with close proximity to coastal destinations such as Aberdyfi and Aberystwyth, making it an ideal setting for private celebrations and retreats in mid-Wales.
