Dolforwyn Castle
Llandyssil, United Kingdom · built 1273
Dolforwyn Castle (Welsh: Castell Dolforwyn) is a Welsh medieval castle above the village of Abermule, Powys. The fortification was established by Llywelyn ap Gruffudd, Prince of Gwynedd in the late 13th century. It is sited on a wooded ridge commanding excellent views of the upper Severn Valley. Dolforwyn Castle is a fine example of a native Welsh castle design as opposed to those built by the Cambro-Normans during the Norman invasion of Wales.
