Jette

Neolithic tools and remains of a Gallo-Roman villa have been found on the territory of Jette, proving the old age of the first settlements in this area. The fact that its first church was dedicated to Saint Peter also indicates early Christianisation. During the Middle Ages, parts of the territory were feudal dependencies of the Duchy of Brabant. Under the duke's protection, the Abbey of Dieleghem was founded in 1095 by the Bishop of Cambrai and administered by Augustinian canons. In 1140, the abbey's monks switched to the rules of the Premonstratensian order. In the 13th century, the abbey now called Dieleghem possessed half of the municipality's territory and played an important social and economic role until the French Revolution.

During the Ancien Régime, Jette was part of the town of Merchtem. In the 17th century, during the period of the Austrian Netherlands, the finance minister under Archdukes Albert and Isabella acquired and refurbished the old 12th century Rivieren castle in Ganshoren, near Jette. In 1654, the minister's son made this estate into a barony, then five years later, into a county, which included Jette and several neighbouring villages.

In the 1790s, the regime that was put in power by the French Revolution curtailed the religious freedoms drastically. The monks were expelled from the abbey in 1796, and most of the buildings demolished the following year. Only the abbot's house was kept, as a leisure house. In 1841, the village of Ganshoren split from Jette. During the following decades, what remained of Jette gradually lost its rural character to become a suburb of Brussels. Its population, which was of around 10,000 in 1900 grew to more than 40,000 in 1971.
