Where should you go if you want to see the most castles? It depends on how you count! Germany is famous for its thousands of castles across each of its 16 semi-autonomous states. It has more than 20,000!
But the greatest number of castles per square mile is actually found in a country called Wales. It’s one of the four countries that make up the United Kingdom. That makes its status roughly equivalent to German states like Bavaria or Spanish autonomous communities like Aragon. When you compare these smaller regions, Wales wins by a landslide—making it the reigning king of castles!
