Olavinlinna Castle, Medieval castle in Savonlinna, Finland
Olavinlinna is a stone fortress built on a rocky island between two lakes and defined by three circular towers and thick defensive walls. The structure features medieval defensive architecture with interior spaces now open to visitors for museum exploration.
The fortress was established in 1475 and originally known as Sankt Olofsborg, built to defend Swedish territorial interests against Russian expansion. After multiple sieges and transfers of control over the centuries, it eventually became part of Finnish territory during the 20th century.
The fortress today houses two museums that showcase the region's dual heritage: one dedicated to military artifacts and castle life, the other to Orthodox religious traditions reflecting the proximity to Eastern cultures. This coexistence of Western and Eastern influences remains visible in how the building functions and what it preserves.
Access to the fortress requires crossing a walkway or short boat transfer since it sits on an island, so planning ahead helps with preparation. Visitors should prepare for uneven paths and stone stairs, particularly in wet weather, making sturdy footwear and appropriate clothing essential.
The fortress was among the first Swedish fortifications specifically designed with circular towers to better deflect cannon fire compared to angular structures. This innovative round design made it an important example of how fortress engineering evolved during that era.
