The Landmark Trust [Alliance member] is delighted to open Llwyn Celyn, a meticulously restored and exceptionally important Grade I-listed house in the Black Mountains in Wales. Built in 1420-21 and hardly changed since around 1690, the rare building has been rescued from dereliction at a cost of £4.2million (with £2.5 million raised by National Lottery players) by Landmark’s team using traditional craft skills, including carpentry, joinery, and masonry. Llwyn Celyn becomes the 200th historically significant building to be saved and sensitively transformed for self-catering holidays by the charity. Channel 4 has filmed the highlights and challenges of the project from start to finish, to be broadcast in the autumn.
