The BBC's award-winning adaptation of Winston Graham's Poldark novels returns for a second season, this evening. Much of the action takes place against a backdrop of National Trust Cornish cliffs, secret coves and iconic engine houses. Shining a light on Cornish mining heritage and National Trust coastal landscapes set within one of the world's largest UNESCO World Heritage Sites, it's worth knowing that Membership of National Trust of Guernsey provides free entry and parking at over 400 National Trust properties and places.
