Things are tough right now ...

They're tough for everyone :( But when coronavirus hit here in the UK, the museum had to close its doors to the public, and we lost practically all our income overnight.

No visitors, no workshops, no events, no school visits... no income. We know that things are tough for everyone right now, but if you can afford to help us through these tough times please donate what you can.

Stay safe, stay at home! There's over 36,000 exhibits here! That should keep you occupied for a bit - get searching!

Or come and get involved on our social media channels ...

Thank you.
