The village of 3,350 inhabitants borders on Budapest. Its neighbourhood became inhabited after the Hungarian conquest.
In 1737 the Roman Catholic parish of Ecser was founded by count Antal Grassalkovich. He also had a single-tower Roman Catholic church built in the place of an old chapel in 1740, in honour of St. Anthony of Padua. This is the only monument building of the village.
In memory of the past, a memorial park was opened in Szabadság square and a monument of World War II was unveiled in 1996. The millenium park with a memorial stone and a national flag was opened in 2000. Ecser is famous for its beautiful national costumes and traditions.
A ball called Nős és Páros (for married couples) is held every year in February, where visitors wear national costumes. The May festival on 1 May is a popular event. At the weekend of Anthony's day in June a patronal feast is held, when the traffic is stopped in the main street called Széchenyi street. The greatest national holiday held in the village is St. Stephen's day on 20 August.
