Renewable energy projects in Wales

Working with our green energy partners, we’re making a difference at our special places across Wales. From stunning solar at Bodnant Garden and Chirk Castle to our holiday cottages that offer greenery, scenery and sustainability, we're harnessing the power of nature and going greener from coast to countryside in our castles and country homes.
