Pen y Garreg


Height – 37m

Length – 161m

Volume – 6055 megalitres


Pen y Garreg is the smallest dam and reservoir. When full, it holds just over two weeks’ worth of water. The tower was built in the Birmingham Baroque style. Pen y Garreg means Head of the Stone. Eustace Tickell was the chief engineer for Pen y Garreg dam, and lived nearby during the nine years of construction (1895 – 1904).

The woods around Pen y Garreg are made up of many species of trees, including Atlantic Sessile Oaks, which are important for many lower plant life forms. Nearby are beautiful carvings in felled tree stumps that had to be felled due to disease. Many of the footpaths in the woods follow the routes of the old railway branches and sidings.

You can book a civil wedding inside the central tower (or walk inside the dam on our dam open days).
