Pihlajavesi

Pihlajavesi is a labyrinth of islands and waterways in the Saimaa lake system. Rather than a single open expanse, its waters wind among wooded shores and rocky islands. At its northern edge the Kyrönsalmi channel connects it to Haukivesi. Here the fortress of Olofsborg was founded in 1475, guarding an important junction of routes through the lakes of Savolax.
