Fingers Crossed for 2021 ...

We're hoping to re-open in the next few months ... fingers crossed! Read More >>>

Please Donate Via Just GivingNo 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.

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