Battle of Grunwald Reenactment — Grunwald Days

Each July, some 1,300–1,400 reenactors from Poland and abroad restage the 1410 Battle of Grunwald on the original battlefield near Stębark, the clash in which the Polish-Lithuanian army broke the Teutonic Knights and killed their Grand Master, Ulrich von Jungingen. A single afternoon performance recreates the battle's key beats — the arrival of the Order's envoys bearing two swords, archery and infantry clashes, and the decisive cavalry charges — in front of a medieval camp that draws over 3,500 people living in period for the weekend.

The battlefield and museum sit at Stębark 70a, 14-107 Gierzwałd, in the triangle of villages Stębark–Grunwald–Łodwigowo. On performance day this loop becomes a one-way circuit (Stębark to Grunwald to Łodwigowo and back), so journey times run well over normal — arrive early. The museum runs paid parking fields beside its own buildings. Watching the reenactment itself is free ("wstęp wolny"), though the site is open-air and not fully fenced.
