Dinas Mawddwy


Minllyn is a planned village associated with the anticipated expansion of industrial enterprises in the Mawddwy area, particularly the development of the slate industry. This was first established around 1800, including some metal extraction, proceeded with the development of a tramway to connect to the Mawddwy Railway, brought to Aberangell after 1865. The impetus came from Edmund Buckley, whose father, a wealthy Manchester industrialist, purchased the estate in 1856. He intended to develop Dinas Mawddwy as a model village, with new education facilities, a hotel, and chapels, served by the railway which was officially opened in 1868, the year he was elevated to the baronetage. Once the main road was diverted out of Dinas Mawddwy, Buckley built a mansion, Plas Dinas in 1864-7, Minllyn Cottages, 1868, and Mawddwy Terraces, 1870-76, all for his estate and industrial workers. The terrace is also known as Meirion Terrace.


Merion House occupies the whole of the S gable. The N side has a 3-panelled door and 4-light shop window under a continuous lintel, which has been inserted in the S half of the gable. The S return end of the terrace has an original sash window and a raised dormer over.

Reasons for Listing

Included, notwithstanding the alterations to the doors and windows, as one of a group of building in Minllyn retaining robust mountain gothic character and demonstrating the hopes of a wealthy industrialist to establish a planned town economically based on local industries, in mid Wales. A good example of a carefully planned estate village, and of group value with other buildings in Minllyn.
