Ruin in the grounds of Mill House, Morland

In the little village of Morland, there is a lovely cafe called the Mill Yard Cafe. By it is a gateway that looks like an entrance to a private house, but visitors to the cafe are allowed in the grounds. We explored the grounds, and found loads of interesting stuff, including this (and other) ruins.
