Savonlinnan halkiuinti

On the morning of July 29th, the lakeside town of Savonlinna transforms into a hub of activity as the Savonlinnan uimaseura ry prepares for their annual open water challenge. The event coincides with St. Olaf’s Day, the city’s official birthday, creating a festive atmosphere where locals and visitors gather along the shorelines. Swimmers typically congregate near the historic villa known as 'Suruton' at Koululahti, readying themselves for the 800-meter crossing. This annual tradition draws a mix of competitive spirits and enthusiasts who return to celebrate the town’s heritage in the very waters that define its geography.

Navigating the historic strait

As you enter the water at Koululahti, you are essentially tracing a route through the Kyrönsalmi strait, the vital artery connecting the Haukivesi and Pihlajavesi lakes. The path is dominated by the looming presence of Olavinlinna, a 15th-century stone fortress that stands as the world's northernmost medieval castle. The fortress was established by Erik Axelsson Tott in 1475 to guard the border, and it remains a constant, imposing companion throughout the swim. Navigating these currents requires a steady hand, as the channel carries a long history of strategic military significance, having shifted from Swedish hands to Russian control during the occupation that lasted from 1743 until 1812.

An industrial and natural backdrop

While the castle provides the most dramatic visual, the lake itself is a living museum of steamship heritage. It is common to see white-hulled vessels like the S/S Savonlinna navigating the same waters you are crossing, serving as a reminder of the region’s reliance on these inland routes. Wetsuits are permitted for the 800-meter distance, which is a practical choice given the northern latitude. As you approach the finish line at the Panimoravintola Huvila pier, you might recall the scale of the regional landscape, including the nearby Kerimäki wooden church, the largest of its kind in the world, which anchors the architectural identity of the surrounding Etelä-Savo region.
