Skip the line at one of the world's most beautiful castles (CNN). Priority entry when arriving between 10:00–12:00. CNN has named Kalmar Castle one of the most beautiful castles in the world - and once you see it, you'll understand why! Since the first stones were laid 800 years ago, it has survived to this day. Redesigned in the 16th century by the Vasa kings, Kalmar Castle is Sweden's best-preserved Renaissance castle and one of the country's most dramatic historic landmarks. This is where Queen Margaret forged the Kalmar Union in 1397 and where centuries of Scandinavian history come alive in remarkable detail. Your admission also includes access to the Children's Castle – a unique family experience where children can meet knights, dress as princesses, complete medieval challenges and take part in activities throughout the castle.
