"Cliffe Castle Museum was originally the spectacular mansion of the local Victorian millionaire and textile manufacturer, Henry Isaac Butterfield. It stands in attractive hillside grounds with greenhouses, aviaries and a children’s play area."

My parents brought me to Cliffe Castle and it's still one of my favourite destinations to bring my 2 boys. There is such a variety of things to do and quirky things to see that you always seem to discover something new.
It's a great educational resource too, without feeling, well, educational. It feels more like fun exploration (which i guess is how education should really feel)
Some of the exhibits, and in particular the rocks and minerals belonged to George Hinchcliffe, Bradford's last great explorer. They were housed at his museum in Heaton, Bradford. I was Hinchcliffe's curator from the age of 14. He had been good friends with my Grandfather and both had spent a lot of time in Africa. George bought most of it back with him!
His collection was left to Cliffe Castle when he passed away.
