The gates of the city are three in number: the gate of Arlon, the gate of Longlier and finally the New Gate or gate Saint Roch.
Few elements are exploitable on the map of Arenberg. (Fig. 41) . Existing gates in the area (Trier Gate of Bastogne) can be used as a reference (Fig. 42) . Geographical proximity and identical historical periods in all likelihood imply a similarity of architecture and materials. This gate should have a bretèche or small machicolation, a large massive door with or without drawbridge to pass a ditch. In the absence of more precise data, the Longlier gate is modeled identically (Fig. 43) .

A projection of the Arlon gate is given in the figure below. it corresponds to the crossroads with the beginning of the "Rue des Oies" because the road of Arlon as we know it was built later (1772). (Fig. 44).
