Aarschot is a city and municipality in the province of Flemish Brabant, in Flanders, Belgium. The municipality comprises the city of Aarschot proper and the towns of Gelrode, Langdorp and Rillaar. On January 1, 2019, Aarschot had a total population of 30,106. The total area is 62.52 km² which gives a population density of 446 inhabitants per km².
It is located in the part of Flemish Brabant called Hageland, located to the east of Leuven. Aarschot is a very typical town with a long history, dating back to the era of the Roman emperors, according to myths. The church, which dominates the look of the city, is built with the typical brown stone quarried from the hills in the surrounding areas. These same hills were in the Middle Ages home to some of the most well-regarded vineyards of Europe. Today the chain hills, which originate in Bolderberg, Heusden-Zolder, and continue as far as Calais in France, are mainly covered with woods and fruit yards.
While the Church of Our Lady definitely leaves its mark on the appearance of the city, nothing defines Aarschot better than the river that passes through it: the Demer. Aarschot is situated in the valley of this brown-colored river.
