Poland's Coastline: The Baltic Sea, Not "Seas"

One Sea, North Border

Poland borders one sea: the Baltic Sea. It lies to the north, providing ~528 km (328 mi) of coastline.

Baltic Sea Details

• Type: Brackish, semi-enclosed marginal sea of the Atlantic.
• Polish Ports: Gdańsk, Gdynia, Szczecin, Świnoujście, Kołobrzeg, Darłowo, Ustka.
• Features: Gulf of Gdańsk (west), Pomeranian Bay (east), Vistula Spit, Hel Peninsula.
• Economy: Shipping, shipbuilding, fisheries, tourism, offshore wind.

Why Not "Seas" (Plural)?

• Poland is in Central Europe—landlocked on three sides.
• Neighbors: Germany (W), Czechia (SW), Slovakia (S), Ukraine (SE), Belarus (E), Lithuania (NE), Russia/Kaliningrad (N).
• No access to North Sea, Black Sea, Mediterranean, etc.

Lagoons ≠ Seas

The Vistula Lagoon (Zalew Wiślany) and Szczecin Lagoon (Zalew Szczeciński) are lagoons (brackish, separated from Baltic by spits/peninsulas)—not separate seas.

Poland's maritime identity is singular: the Baltic.
