A young fisherman named Wars lived on the Vistula River and loved fishing. One night, he saw a beautiful mermaid named Sawa singing in the water. Wars fell in love with her and asked her to be his wife. Sawa agreed and turned into a human. They married and lived happily ever after. The capital of Poland, Warsaw, is said to derive its name from their names combined: Wars and Sawa. The mermaid is also featured on the coat of arms of Warsaw.
