Stirling Castle, located in Scotland, is a massive and historically significant fortress perched on a crag with steep cliffs for defense. It's been around since the early 12th century and has seen its fair share of action, including sieges during the Wars of Scottish Independence. Over the years, it served as a royal residence where kings and queens were crowned, born, or died. Today, it's a popular tourist spot managed by Historic Environment Scotland, attracting visitors with its rich history and stunning architecture.
