St. Dominic's Fair in Gdansk is Poland's longest-running summer market and cultural tradition.

The St. Dominic's Fair (Jarmark św. Dominika) is one of Europe's oldest market fairs, with roots tracing to the 13th-14th century. Held in Gdansk's historic old town, this month-long summer tradition combines traditional marketplace commerce with contemporary cultural programming — the 2026 edition marks its 766th year. The fair transforms the ancient city's central squares into an open-air venue showcasing Polish crafts, regional products, street food, folk performances, and cultural events that celebrate Gdansk's maritime heritage and merchant traditions.

The fair's unique blend of history and living culture makes it essential for understanding Polish urban life. Visitors browse artisan goods, traditional clothing, regional delicacies, and local crafts while enjoying street performances, folk music, and theater. The July-August timing captures peak summer tourism when Gdansk's medieval architecture is most captivating. Unlike commercial shopping centers, the fair preserves genuine marketplace culture and community celebration. This is one of Poland's most significant summer cultural events and a window into centuries of Baltic trading traditions.
