As an independent charity, our Museum relies on the generosity of individuals like you. Our buildings need continually looking after and all funds raised are invested back into the Museum. Your contribution, whether big or small, ensures the continuous enjoyment of this unique space for everyone. If you're a UK taxpayer, please choose to Gift Aid at the checkout, this will amplify your admission, membership or donation by an additional 25% and will give us us a vital bit of additional income at no extra cost to you.

Thank you for being a vital part of our mission to maintain the museum's special place in history and community.
