Eilean Donan Castle, Scotland

This image was taken northwest of the castle so the island is more prominent.

Although first inhabited around the 6th century, the first fortified castle was built in the mid 13th century and stood guard over the lands of Kintail. Since then, at least four different versions of the castle have been built and re-built as the feudal history of Scotland unfolded through the centuries.
