Leuven (UKˈlɜːvən, ˈløːvə(n)) or Louvain (luːˈvæ̃, USalsoluːˈveɪn, luvɛ̃; Löwen ˈløːvn̩) is the capital and largest city of the province of Flemish Brabant in the Flemish Region of Belgium. It is located about east of Brussels. The municipality itself comprises the historic city and the former neighbouring municipalities of Heverlee, Kessel-Lo, a part of Korbeek-Lo, Wilsele and Wijgmaal. It is the eighth largest city in Belgium, with more than 100,244 inhabitants. KU Leuven, Belgium's largest university, has its flagship campus in Leuven, which has been a university city since 1425. This makes it the oldest university city in the Low Countries. The city is home of the headquarters of Anheuser-Busch InBev, the world's largest beer brewer and sixth-largest fast-moving consumer goods company. The earliest mention of Leuven (Loven) dates from 891, when a Viking army was defeated by the Frankish king Arnulf of Carinthia (see: Battle of Leuven). According to a legend, the city's red and white arms depict the blood-stained shores of the river Dyle after this battle, similarly to the flag of Austria. Situated beside this river, and near to the stronghold of the Dukes of Brabant, Leuven became the most important centre of trade in the duchy between the 11th and 14th centuries. A token of its former importance as a centre of cloth manufacture is shown in that ordinary linen cloth was known, in late-14th-century and 15th-century texts, as lewyn (other spellings: Leuwyn, Levyne, Lewan(e), Lovanium, Louvain). In the 15th century, a new golden era began with the founding of the largest and oldest university in the Low Countries, the University of Leuven, in 1425. Prestigious buildings like the Town Hall and the Saint Peter's Church (itself designated a UNESCO World Heritage Site in 1999) were constructed. The art of painting flourished with painters such as Dirk Bouts, Albrecht Bouts and Jan Rombouts the Elder. The painter Quinten Metsys was born and trained in Leuven.
