Hen Dy is the upper part of Llannerch y Cawr Longhouse, a Grade II* listed building which dates back to the 16th Century. The property was restored in 1999 retaining many of the traditional features and is now utilised as two self catered semi detached properties, the Upper - Hen Dy and Lower - Y Beudy. Both halves can be booked together and attracts a discount of 5% (on a full weeks price).

Llannerch y Cawr longhouse is situated close to the Dôl y Mynach Reservoir in the Claerwen Valley and has easy access to the main Claerwen Valley road. The property is just 7 miles outside the town of Rhayader, approximately 4.5 miles from the Elan Valley Visitors Centre and 6 miles from Penbont Tearooms.

Hen Dy would historically have been the people end of the Longhouse and as such boasts authentic flagstone flooring, wide open fireplace, beamed ceilings, stone (uneven) twisting staircase* and even bats in the roof space!

*Due to the unlevel flooring and twisting staircase this property is not advisable for the infirm or young children.  

During July and August, the bats can be very disruptive, with scratching noises and lots of too-ing and fro-ing. 

The property is off-grid and is operated by generator power. There is no phone signal or wifi at the property so you really can get away from it all
