Getting dark

Happens now mid afternoon. We had meant to go for a walk after lunch but by the time we had finished the light was fading.
St Andrews castle, a ruin so for derelict Sunday.
You can see where there must have been a saltwater swimming pool, another less obvious aspect of the dereliction. Now there's such a craze for "wild swimming" it would be great to reinstate some of these, there are a few up the Fife Coast.
