From there, Toledo went through various invasions and upheavals too complicated to explain here. No matter what, though, its location in the middle of the peninsula by a river was a selling point. The most important parts of the city were built on a steep hill behind walls. As these things go, it was a relatively safe spot. No wonder the city's wealthiest citizens lived there.
Once matters settled down in Toledo and the capital was moved to nearby Madrid, it became known for its history. UNESCO designated it as a World Heritage Site. Even so, it's still alive - based on all the shops that cater to tourists within those walls. People still live there now; I hear it's pricey.
You can see Alcazar - a stone building on top of the hill - in this
photo. It was a stone palace used by the Romans in the third century.
It was also the site of an intense battle during the Spanish Civil War.
By the way, Toledo has several sister cities around the world - including, of course, Toledo, Ohio.
