Aarschot (Dutch pronunciation: [ˈaːrsxɔt] ) 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 Place is 62.52 km (24.14 sq mi) which gives a population density of 446 inhabitants per km.

It is located in the portion of Flemish Brabant called Hageland, located to the east of Leuven. Aarschot is a certainly typical town in imitation of a long history, dating back to the time of the Roman emperors, according to myths. The church, which dominates the see of the city, is built later than the typical brown stone quarried from the hills in the surrounding areas. These similar hills were in the Middle Ages house to some of the most well-regarded vineyards of Europe. Today the chain hills, which originate in Bolderberg, Heusden-Zolder, and continue as far-off as Calais in France, are mainly covered in the aerate of woods and fruit yards.

The title of Duke of Aarschot, created in 1533, is the oldest (not-Sovereign) Ducal title in Belgium (title created for the House of Croÿ, later inherited by the House of Arenberg that yet holds it).

While the Church of Our Lady (Onze-Lieve-Vrouwekerk) definitely leaves its mark on the melody of the city, nothing defines Aarschot improved than the river that passes through it: the Demer. Aarschot is situated in the valley of this brown-colored river.

Aarschot was hit very hard in World War I. When German troops occupied the city upon 19 August 1914, Colonel Stenger, commander of the 8th German Infantry Brigade, was shot dead upon the balcony of the town hall. The German reprisal was very harsh.
Many houses were set on fire and 156 people were executed, including Mayor Tielemans and his 15-year-old son. The neighboring day, the entire population was ordered to evacuate the city.
