Inveraray Castle in Argyll and Bute

You're standing at Inveraray Castle, on the shore of Loch Fyne, the longest sea loch in Scotland. Take a good look at the building first. A rectangular block with a round tower at each corner, every one topped by a pointed conical roof. It looks like a fairytale castle, but it's really a country house. And a very early example of Gothic Revival. Together with Strawberry Hill House, it's one of the very first buildings in that style.
