Once a hive of industrial activity, this incredible historic place has very much been reclaimed by nature and there is a wealth of wonderful wildlife for you to discover there.

There’ll be lots to get involved with a nature scavenger trail and make and take activities.

There’s no need to book and you don’t need to be members. Just come along and enjoy!
