River and town walk

Cwmdauddwr (rarely referred to by its correct full name of Llansanffraid Cwmteuddwr) is a village in Powys, Wales. It is contiguous with the town of Rhayader on the opposite side of the River Wye. The village is located on the B4518 road linking Rhayader with the Elan Valley Reservoirs.The parish of Cwmdauddwr corresponds approximately to the medieval commote of Cwmwd Deuddwr (English: Commote of the Confluence, literally: commote of the two waters).

Rhayader railway station was a station serving the town of Rhayader, Powys, on the Mid Wales Railway line.It was opened in 1864 in Cwmdauddwr, a village on the opposite bank of the River Wye. The line, which took over 5 years to build, was closed in 1962 and dismantled within months.The station was the junction for the Elan Valley Railway which was in operation between 1896 and 1916.

Rhayader was, from 1894 to 1974, a rural district in the administrative county of Radnorshire, Wales.The district was formed by the Local Government Act 1894, based on the existing Rhayader Rural Sanitary District. The rural sanitary district had included the Brecknockshire parish of Llanwrthwl, and this was administered by Rhayader Rural District Council until 1934, when it was transferred to Builth Rural District.

The Old Swan is a former historic public house at the centre of Rhayader, Powys, Wales. The buildings are timber framed and while there is a datestone of 1683, it is very probable that it is late 16th century, if not earlier. The buildings still have their original roof of stone flags and distinctive leaniing stone chimney stacks.
