Beautiful church - well worth exploring

Elan Valley is a mountain bikers dream. A mix of natural trails that follow the reservoirs and crest the lofty tops of each valley. There's also a great trailhead in the middle of the valley at Nantgwyllt for some great flowing singletrack.

The old church, along with the manor house and nearby cottages, were enveloped by the waters and lost forever when Caban Coch dam was built. Among the lost houses was Cwm Elan, once the home of poet Percy Bysshe Shelley's uncle. Shelley visited on several occasions and fell in love with the area. In 1812 he tried to buy Nantgwyllt House, as a home to settle into with his wife Harriet. The old church at Nantgwyllt may have been lost, but in 1898 a new church was begun on high ground overlooking the Garreg-ddu viaduct. The architect was Stephen W Williams, who also built Elan Village to house workmen labouring to build the dams. The new church was erected at the southern end of the viaduct.

The Craig Goch Dam, often called the Top dam, is a masonry dam in the Elan Valley of Wales and creates the upper-most of the Elan Valley Reservoirs. Construction on the dam began in 1897, and it was completed in 1904. The primary purpose of the dam and the other reservoirs is to supply Birmingham with water. In 1997, a 480 kW hydroelectric generator began operation at the dam.
