This unique and slightly eerie treasure is situated in Victoria Park and is a collection of fossil trees and surrounding rocks which are the remains of an ancient forest, more than 330 million years old.  Preserved in mud and shale, which seeped into the trunks thus preserving them, they became sandstone casts of  Carboniferous "Lepidodendron" trees. Discovered by workmen in 1887 who were cutting a path in the new park,  an ingenious move was taken. Instead of relocating them to a museum, they were left in situ with a building erected to protect them from the elements.  Spooky but fascinating.
