These castle walls
I recently took two days off and spent them driving around the west of Scotland. On the coast, and near the island of Skye, is the castle of Eilean Donan. It is sometimes described as Scotland’s most photographed building, and it features in recent TV advertisements for Scottish tourism. Although it looks rather ancient, it is in fact a reconstruction carried out in the early 20th century; before that it had been in ruins for some considerable time, and not much of the original building had remained. You can read more about it here.
Since it has been photographed so much, I thought I might add one more picture. Here it is.
