History

This is a very old village, known since 1068.
A train line was built between Paris to Chartres via Gallardon, at the beginning of the 20th century, with a station at Gometz-le-Châtel. It was used from 1931 to 1939, but there is no traffic nowadays. Paris RER, B line, can be used to go there by train Bures-sur-Yvette (Paris RER) or La Hacquinière (Paris RER).
An experimental Aérotrain was built, from Gometz-le-Châtel to Limours, for a trial, from 1966 to 1977, a creation of Jean Bertin (railway engineer). This experiment was replaced by the TGV, operating currently.
