Free Imperial City of Aachen
The Free Imperial City of Aachen, also known in English by its French name of Aix-la-Chapelle and today known simply as Aachen, was a Free Imperial City and spa of the Holy Roman Empire west of Cologne and southeast of the Low Countries, in the Lower Rhenish–Westphalian Circle. The pilgrimages, the Coronation of the Holy Roman Emperor, flourishing industries and the privileges conferred by various emperors made it one of the most prosperous market towns of the Holy Roman Empire.
