Still standing after all these years

If you ever saw the TV show Restoration - presented by a guy called Ptolemy - you might remember this place, Portencross Castle on the Ayrshire coast.
It's been here since the 14th century and is very much a ruin but a pretty impressive one. A local group is trying to save it.
Interesting that the Scottish Saltire flies from it. Apparently a number of Scottish kings stayed here over the centuries.
