Bucholly Castle, Caithness, Scotland

Bucholly is a good example of a fortified promontory, a type of castle common in Scotland. Dating to the 15th century, the promontory was separated from the mainland by a massive rock-cut ditch meaning the castle could only be reached via a drawbridge to the gate. This photo shows how the gatehouse building rises from the sheer cliff face, and I like the way that the masonry echoes the bedrock below, and draws the eye into the body of the castle behind - which contains grass-covered ruins of two ranges of buildings on either side of a narrow courtyard.
