Edinburgh's forgotten castle that was destroyed by builders due to 'admin error'

Edinburgh Castle is a world-famous landmark that's loved and treasured by locals and tourists alike - but imagine if it was accidentally destroyed due to an administrative error.

While it's hard to believe this could happen to a scheduled monument of such renown, this is precisely what befell another of the capital's ancient fortresses not so long ago.

First documented in 1479, Granton Castle was the home of Scottish nobility for hundreds of years before falling into disrepair in the early Georgian era.
