There is one commissioner each, appointed by the mayor, for the parks and boulevards, police and public works departments.
Handsome boulevards now skirt the town, the streets of which are clean and well-ordered, and a large public garden extends at the foot of the citadel, with a statue of Enguerrand de Monstrelet the chronicler.
It has an extensive system of boulevards, parkways and parks (aggregating 2465 acres in 1908).
The former, situated on the top of the hill, is of comparatively small extent, and forms almost a parallelogram, surrounded by ramparts of the 13th century, and, outside them, by boulevards, and entered by ancient gateways.
The site thus gained was converted into new boulevards, while the railway to Neuss and Aix-la-Chapelle was diverted through the suburb of Bilk and thence across the Rhine by an iron bridge.
