The battlefield of Grunwald can be found about 200km north of Warsaw just off the A7 road to Gdansk.

The Battle of Grunwald (or 1st Battle of Tannenberg) took place on July 15, 1410 with the Kingdom of Poland and the Grand Duchy of Lithuania ranged against the Knights of the Teutonic Order, led by the Grand Master Ulrich von Jungingen. It was the decisive engagement in the Polish-Lithuanian-Teutonic War (1409-1411) and one of the greatest battles of medieval Europe. The battle saw the Monastic State of the Teutonic Knights decisively defeated — their order never recovered its former power.
