When you talk about old, you think of the first things written down—the beginning of recorded history. Everything before that just seems to be mysterious and unexplainable, but luckily our ancestors had so much to say that we are constantly uncovering the past. Unfortunately for them, the Edinburgh Castle is so incredibly old, but the time people were writing about it, it's story was already a huge mystery.
Edinburgh Castle is a Scottish fortress that sits atop Castle Rock. Archeologists have gathered that people have inhabited the rock since at least the Iron Age in 2nd century AD, though earlier settlements are very likely. Ptolemy's map of the area, created in the 2nd century AD, shows a settlement named “rock place” which may refer to Castle Rock.
Many various writers throughout history have credited different rulers with building the Edinburgh Castle, some claim as early as 989 BC. No matter if that early of simply existing from the Iron Age, Castle Rock is the longest continually occupied site in Scotland.
Multiple digs throughout the 1990s have raised more evidence that seems to contradict every theory on the location and merely adding more mystery to one of the oldest castles still standing.
