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.

Cumberland House will be open this Bank Holiday Monday (6 May), 10am to 5pm.

Please note, Cumberland House will be closed to visitors from 7 to 20 May inclusive. 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.
