Dominating the city from its volcanic rock, Edinburgh Castle is one of the oldest fortified places in Europe.

In fact, it is the most besieged place in Great Britain, and remained in military use well into the past century. Over the years Edinburgh Castle has attracted countless visitors with an interest in Scotland's dramatic history. This book invites visitors to explore the castle and learn about its extraordinary history and discover some of its fascinating secrets.
