The Aachen Landgraben is the name given to the fortifications along the almost 70 km long border of the former Aachen Empire. Individual sections can be documented as early as the 14th and 15th centuries, but it was not until the beginning of the 17th century that the construction of the Landwehr was completed and on 11 April 1611 Albrecht VII von Habsburg, the acting regent of the Spanish Netherlands in Brussels, contractually legitimized it with the aldermen and the city council in Aachen.
