2023-10-20 00:00:00 Display your Historic Houses membership card digitally on your device. Historic Houses members enjoy hundreds of offers of free entry to independent historic house, castle, and garden attractions across the UK when they show their physical card. You can now find and display your card details on your phone. These aren’t a substitute for your physical card, which you should still carry with you. Displaying your card details digitally does not guarantee that a participating attraction will accept them as proof of membership.
