Welcome to the natural history museum of Portsmouth

You can take a walk through the A-Z of Natural History, get up close with a huge dinosaur, and visit our wonderful Butterfly House.

Cumberland House Natural History Museum is free to visit.

The museum is open Tuesday to Sunday, 10am-5pm. Last admission is 4.30pm to the museum and 4pm to the Butterfly House.

Please note, Cumberland House is closed to visitors until 21 May. This is for essential works around the building to be completed safely. We apologise for any inconvenience this may cause. Our other museum sites (including Portsmouth Museum and Art Gallery, Southsea Castle, and The D-Day Story) are open as usual.
