You can just about see the rectangle of the sea pool, next to the sea lion enclosure. I was tempted to take a dip, but I forgot my costume.
Interestingly, this pool was originally where suspected witches were 'swum'. The witches had their right thumb tied to the left big toe and vice versa before they were 'swum'.
(I’m reading Robert Rankin’s «The witches of Chiswick» at the moment. No ‘swumming’ so far…)
