The most northerly of Scotland's great houses

Dunrobin Castle, the seat of the Earl of Sutherland, is just outside the town of Golspie, 50 miles north of Inverness.

The Caledonian Canal was completed in 1822

It links the west coast of Scotland (close to Atlantic waters) with the North sea.  The canal was built by Thomas Telford and is one of the great feats of British civil engineering.

Of course, it's still in use and you can see the lock gates and bridges working most days, certainly in the summer.

Yachts and all manner of vessels use this waterway regularly.
