The commune was created around 1100 where the church of St. Martin was located. During the Middle Ages it was administered at some points by the lords of the Castle of Gières, and at other times by the bishop of Grenoble, who had religious and seigniorial disputes with the former.^[5][6] The city remained a mostly rural area, until the 19th century, when it saw its first industrial developments with the opening of roads and railways. In the 1950s and the 1960s the city saw a "new era" with a significant demographic expansion caused by the installation of the University of Grenoble.^[5]

The city is limited at the north by the Isère. It is located in an area historically prone to flooding by it and by the Mogne and Sonnant streams, though the floods stopped since the construction of dykes and the channelization of the Mogne and Sonnant streams.^[7]
