The Battle of Mogyoród took place here on 14 March 1074, between Solomon, King of Hungary and his cousins Géza and Ladislaus, who were claiming rights to the throne.

The name of the town can be found in many documents as "Mogyoród" in the Western alphabet, in Turkish tax papers as "Magoród" and "Mogyorós", and in foreign ecclesiastical charters as "Monorond", "Mangerat", "Munerod", and "Mamorade".

Ladislaus I of Hungary right before the fight – thanks to his visions – made a similar promise that a church to Saint Martin would be built at the place of the battle.

In March 1241, the Tatars mounted an offensive against the village and monastery, and continued until the Danube, where they attacked Vác.

In the first trierce of the 14th century, the existence of the abbey of Mogyoród was in danger but thanks to the abbot of Ggaramszentbenedek and the bishop of Eger, between 1338 and 1342 it became alive again.

The abbey became more and more important and about a 70-year of prosperity began: in 1366 it was the place of the chapter, and in the beginning of the 15th century, the abbots followed orders of the pope in big projects.

Other main sight of the settlement is the Aquaréna [hu] Aquapark, which is one of Hungary's most famous water-amusement park.

Famous people usually visit the park (for instance Formula One drivers, artists, singers, celebrities, etc.).
