Input: Question: Which of the two Abbeys that included Woluwe's territory was built first? Passage:Several archaeological finds on the territory of Woluwe-Saint-Lambert show traces of human activity during the Bronze Age. The first historical mention of the village, however, dates from the 11th century, when some of the forested land near the Woluwe River was cleared for farming. A church was built and dedicated to Saint Lambert, the 7th-century bishop of Maastricht who was martyred in Liège. At the end of the 12th century, the rights to the parish of Saint Lambert were given to the canons of the chapter of St. Michael and Gudula in Brussels. Various charitable organizations and hospitals then started acquiring land in this area. Throughout the Middle Ages, Woluwe was part of the Duchy of Brabant, governed under the usual feudal arrangement of those times. Among the Dukes' vassals were some powerful local lords and landowners. Some of Woluwe's territory also belonged to the powerful Forest Abbey (Vorst in Dutch) and Park Abbey.
