Although they were often erected a century ago (very often after the First World War from 1914 to 1918), the "war memorials" found almost everywhere in villages and towns are by no means mere relics of a bygone era. They still commemorate the victims of war and tyranny today. The design of the memorials varies from place to place, but they all have one thing in common: they continually remind us of the need to preserve peace.

This place is a gem. A bit of an oasis in a desert if you are on your bike and want a hot drink or to fill your water bottles. It is an honesty cafe in a house opposite Moduron Hafod Garage. Especially helpful if you are doing the Trans Cambrian Way in 3 days, just stay on the road at Ysbyty Ystwyth and drop down to Pont-rhyd-y-groes. You will have to climb back up to rejoin the route though (Hafodty road is most direct but steep!)

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.
