Battery

Or whatever you call somewhere bats live. When they were demolishing the old Comprehensive School they found bats living in the structure so they built a new bat haven in the new building. It's the bit with the swirly brickwork on the left of the photo. I like the new building but I have to feel sorry for my daughter who had to endure her last 3 years of school in portakabins and other temporary structures. Did OK though.
