The fort that withstood the Hanseatic forces

The fort Falsterbohus, located in Skåne County, Sweden, was built in the 13th century as a strategic defense against the invading Hanseatic forces. The castle was built on a man-made square island with dimensions of 42 x 42 meters. It was fortified with a nearly square enclosed courtyard, about 33 meters long and 28 meters wide. Surrounded by layers of walls, moats, and a wave breaker outside the outer moat, the fort was designed to protect the coastal town from invaders and sea threats. Today, the remnants of Falsterbohus stand as a reminder of a time when this county was strategically important.
