Strait of Baltiysk

The Strait of Baltiysk (Cieśnina Piławska, Pillauer Tief) is a strait enabling passage from the Baltic Sea into the brackish Vistula Lagoon, located in Kaliningrad Oblast, Russia. The strait, initially a storm-created gat and later expanded via construction, separates the Vistula Spit on the south side from the peninsula containing the town of Baltiysk on the north side (called Pillau Peninsula in Russia, after the Pillau Fortress). The latter peninsula was part of the Vistula Spit in the 15th century and now is part of the larger Sambia Peninsula.
