Llancaiach Fawr, which was built in 1550 by the Prichard family, is considered to be one of the most important Gentry houses to have survived from the 16th and 17th century period.
Its £943,200 Heritage Lottery Fund grant will help fund:
- Restoration of a stone roof, removal of inappropriate modern features and repair and opening of the attic
- Installation of an external staircase tower and platform lift to allow wheelchair users access to the upper floors
- Conservation work on the manor
It will also help:
- Improve physical and sensory interpretation, including open fires, sound and lighting, to create an atmosphere of 17th Century domestic life
- Involve young people in learning about their local history
- Pay for a Development and Outreach Officer, who will manage community activities
Llancaiach Fawr says it hopes to attract 80,000 annual visitors by 2020 as a result of the improvements.
