ISBN9789075230291: “We have some information on the early medieval situation from two 9th-century texts, in which the locus Aalst is first mentioned. Both texts are part of the property lists of the abbey of Lobbes, made around 868–869. A polyptycum lists the properties of the abbey by pagus, mentioning Alosta in the pagus Bragbattensis.”
