A mild day, taste of Spring. Walking from the nature reserve at Caerlaverock on the Solway Firth to the castle, famously besieged by Edward 1 in 1300, then blown up in 1640 at the beginning of the Civil War. Caerlaverock's a Welsh word, a relic of the area being part of the ancient Kingdom of Strathclyde. In the background over the estuary of the Nith is Criffel (named by the Norse Vikings- Crow Mountain). And on the other side the iron age fort of Wardlaw. This was a major crossing point from the English side of the Solway, so there's a Roman harbour here, too.
