Tienen (Dutch pronunciation: [ˈtinə(n)] ⓘ; French: Tirlemont [tiʁləmɔ̃]) is a city and municipality in the province of Flemish Brabant, in Flanders, Belgium.
The municipality comprises Tienen itself and the towns of Bost, Goetsenhoven, Hakendover, Kumtich, Oorbeek, Oplinter, Sint-Margriete-Houtem and Vissenaken.
[2] Its capture resulted in one of the most serious atrocities of the Dutch Revolt; the town was sacked, over 200 civilians killed and many buildings damaged, including Catholic churches and monasteries.
[4] This was the last victory for the veteran Dumouriez, hero of Valmy and Jemappes; within a week, his army suffered such catastrophic defeats that he defected to the French Royalists.
It is the site of facilities owned by Citrique Belge, that produces citric acid, and Havells Sylvania, a manufacturer of energy saving lamps.
