Following a huge renovation project, The Butterfly House at Cumberland House Natural History Museum is now fully open. Come and see a range of neo-tropical butterflies from South America, plus our new puparium where the pupae can transform. The butterflies will be in flight until October.


A full range of products are available in our museum shop for all ages, but particularly for young people.


The Museum is free entry to all but young people under 13 need to be accompanied by an older person.
