Keizersberg Abbey

St Gertrude's Abbey is a complex of former monastic buildings in Leuven, Belgium. An Augustinian priory founded in 1206 was suppressed in 1797. After restoration, the monastic buildings were used between 1917 and 1968 by Benedictine nuns as a house of studies and student residence.

The siege of Leuven (24 June – 4 July 1635) was an important siege in the Thirty Years' War in which a Franco-Dutch army under Frederick Henry of Orange and the French Marshals Urbain de Maillé-Brezé and Gaspard III de Coligny, who had invaded the Spanish Netherlands from two sides, laid siege to the city of Leuven, defended by a force of 4,000 comprising local citizen and student militias with Walloons, Germans, Spanish and Irish of the Army of Flanders under Anthonie Schetz, Baron of Grobbendonck. Poor organization and logistics and the spread of sickness among the French, along with the appearance of an Imperial-Spanish relief army of 11,000 under Cardinal-Infante Ferdinand and Ottavio Piccolomini, forced the invading army to lift the siege. This failure allowed the Spanish forces to take the initiative and soon the invaders were forced into a headlong retreat.

The Battle of Leuven, also called the Battle of the River Dyle, was fought in September 891 between East Francia and the Vikings. The existence of this battle is known due to several different chronicles, including the Annales Fuldenses and the Anglo-Saxon Chronicle. The Annales Fuldenses are royal chronicles of the East Frankish kingdom covering the years 714-901 AD. The Battle of the Dyle occurred near the present-day location of the city of Leuven in Belgium. In the 880s the Vikings established a camp there that they used as a base of operations from which to launch raids into the fractured Frankish kingdom. Efforts to verify the report of the battle from the Annales Fuldenses, specifically the huge loss of life on the Viking side, have been hindered by the lack of archaeological excavations in Belgium.
