Newton House
Standing within the Dinefwr estate is a Grade II listed house which was the home of the dependents of The Lord Rhys. It is now cared for by the National Trust and is well worth a visit as it dates back to 1660 and was built by Edward Rice. The current gothic facade dates from the 1850’s but many of the original features can still be seen. There is a beautiful tea room and wonderful gardens as well as a second hand book shop.

Llyn Brianne
Llyn Brianne is a man made reservoir in the headwaters of the river Towy. It was constructed by Wimpy in the 1960’s and 1970’s in order to regulate the flow in the Towy to support water abstraction at Nantgaradeg in the lower reaches of the river near Carmarthen, providing water to the Felindre water treatment . The treated water is piped to a large area of South Wales. Fanog Farm was taken over by the forestry commission whilst the reservoir was being constructed and allowed to become derelict when the reservoir levels become low, the ruins can sometimes be seen and provide a view of Welsh life in previous times, it would have been a beautiful place to live but somewhat remote.
