Here is a close-up (above), taken from a respectable distance with a zoom lens.
The photo above shows what a lot of nooks and crevices there are in the villa ...
... and these provide the ideal habitat not only for lizards but also for rare Roman snails. These snails (Helix Pomatia) have been at Chedworth since they were introduced by the Romans. They are protected by law.
We visited the tea room before leaving, and noticed this little chap on one of the chairs! There were newts in the nymphaeum and we came away feeling that while we had greatly enjoyed re-discovering the Roman remains, we had also had a rich and unexpected wildlife experience.
