This was once considered one of the Seven Seas: it is the Caspian as seen from Baku in Azerbaijan.
To be precise it's the view from the Maiden Tower which I've just come down from, having done the Lonely Planet walking tour in reverse. In case anyone is wondering that's means beginning at the end point and finishing at the start point, not walking backwards!
More to come, but there is a work related point to this trip, so maybe not straight away.
