Dolgellau   Dolgellau is situated at the base of Cader Idris at the confluence of the Afon Wnion and Afon Aran. Between the 16th and 19th centuries Dolgellau was a major centre for the woollen industry and the town had many weaving sheds and fulling mills (principally established along the Afon Aran). By the 1610 Camden described Dolgellau as a 'little market town'. Gold ore was found in quartz veins in Clogau shale and in the Vigra Flags at several locations around Dolgellau and gold mining developed as a major industry in the area during the 19th century. Gold mining still features in the local economy. Until 1973 Dolgellau was the county town for Meirionydd; subsequently, with the establishment of Gwynedd the local government became centred on Caernarfon. The town is still an important market centre with Friday being Market Day. It is also the venue for Gwyl Amaeth Dolgellau (the Farming Festival). Dolgellau serves as a service centre for a wide rural area, as evidenced from the presence of a hospital and college. In 1991 the town had a population of 2,261. Much of the town centre is a designated conservation area and contains many fine examples of vernacular architecture, both residential and commercial.
