This is the entrance to a set of caves which might once have been a sandstone mine. They were definitely used as an air-raid shelter in the second world war. Now, they are in someone's back garden! I want one of these.
We looked around as part of a bat survey. This time, we didn't find any bats here, but there were a couple of overwintering moths.

There were smaller moths as well, two specimens of the interesting Twenty-plume Moth:

It was good to see some summer moths in the middle of winter!
