The town is 18 km from Budapest next to the M3 freeway in the valley of the Gödöllői-hills. Its highest point is the Somlyó-mountain, (Gyertyános 326m) which can be seen from the freeway or the HÉV. Many people move here because of its proximity to Budapest while retaining the quiet of the country. It is the location every year for the Formula 1 Hungarian Grand Prix.

The name of the town derives from the Hungarian word for hazelnut, and can be roughly translated as "rich in hazelnuts". Although today there are only a few hazelnut bushes, local tradition holds that the town's presbytery still holds the town's first.

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".

The most authentic paper of the battle is a charter from the Holy Roman Empire from the end of the year 1074, which didn't tell the place of the battle but contains that the Hungarian king, Salamon lost the battle. The next resource in time is from the 'Képes Krónika' (Chronicon Pictum) which tell us details of the battle: (free translate by myself) 'The only important place near to the battle was Zymgota (Cinkota), which is near to Monorod ("rich in hazelnuts") mountain on which the battle was fought. The only way to find the exact place to find the massgrave which was created by the fight, cause the writings from that time can't be used now because those aren't true for the lie of the land of these days (mostly cause of the location of the forests and the meadows).
