Borgholm is one of the largest and best preserved medieval castles in the Nordic countries. It was built on a foundation of rock and was originally surrounded by a moat. This moat was filled over time with sediment, which resulted in the castle becoming a huge, impressive structure. The castle is now located in the middle of a city.
