Eaton Chalk Pit
Eaton Chalk Pit is a biological Site of Special Scientific Interest on the southern outskirts of Norwich in Norfolk, England.
These former chalk mines are used by hibernating bats and the site has been monitored over a long period for research into bat ecology. Up to 40 bats use the mines and the main species are Daubenton's, Natterer's and brown long-eared bats.
There is no public access to the site.
