At one time, Scotland was home to more than 4,000 castles. It's an extraordinary number for such a small country and today, around 3,000 still stand.
Some are world famous, others have inspired great works of literature, while others have lit up the silver screen.
There are grand, ticketed visitor attractions but there are others which are unassuming structures so tucked away that only the locals seem to know about them.
From the triangular-shaped Caerlaverock Castle in Dumfries and Galloway to the imposing New Slains Castle in Aberdeenshire, and from the magnificent fortress that dominates the Edinburgh skyline to the haunting battlements that stand on the banks of Loch Ness, each tower tells a story, every turret holds a secret and, together, they span centuries of fascinating Scottish history.
A History and Guide to Scottish Castles explores the history, architecture, and legends of some of these fascinating fortresses and looks at why they are so appealing to visitors today.
