The Battle of Grunwald re-enactment recreates 15 July 1410, when the Polish-Lithuanian army under King Władysław Jagiełło and Grand Duke Vytautas defeated the Teutonic Order in one of the largest battles of medieval Europe. It is staged on the original battlefield near the village of Stębark (Grunwald commune) in Warmia-Masuria, beside the Museum of the Battle of Grunwald, and is the centrepiece of the multi-day ‘Dni Grunwaldu’ (Grunwald Days).
The battle is re-enacted on the Saturday closest to the anniversary, usually at 15:00. In 2026 (the 28th re-enactment) about 1,300–1,400 armoured fighters took the field and more than 3,500 people in total took part in the knights’ camp, including craftspeople, musicians and historians; spectator numbers are regularly quoted at around 100,000. The days around the battle include camp life, tournaments, concerts, a medieval fair, archery and evening shows.
The first re-enactment was held in 1998 and it has run every year since, with one pandemic-year gap. Entry to the battlefield and camps is free. The event is organised by the Marshal of the Warmia-Masuria region with Fundacja Grunwald; the museum on the site is open year-round.
The site is rural: come early, bring water, sun protection and something to sit on, and expect slow traffic on the access roads after the battle. Dni Grunwaldu 2026 ran 15–19 July with the battle on Saturday 18 July; the organisers have already announced the 2027 battle for Saturday 17 July 2027 at 15:00.
