Calling all castle chasers! Castles are these magnificent buildings that are grandiose. Many of them were built in medieval times to protect from enemies. Surely, you’ve heard of castles in fair tales — the fortified walls, the moats, and the towers. There are such buildings throughout the world. Some look like the castles in those fairy tales you read as a kid, but others look different. Some castles have existed for thousands of years, whereas others are only a couple hundred years old. Let’s take a look at the 15 oldest castles in the world.
