The small squares and alleys of the old town are picturesque.

The Laufenburg was built in the 12th century by the Dukes of Limburg. Since the 17th century it has only existed as a ruin. In 1895 the battlements of the round corner towers were renewed. The current restaurant is closed on Mondays.

Small winding streets with houses made of local limestone and carved bluestone on doors, windows and wall edges look back at you as you walk through the old town of Stolberg. As you stroll, you take your time to look at the traditional house facades and notice that despite the old town's long history of development and the influence of the industrial era, a homogeneous appearance has emerged. You walk through Burgstrasse, Schartstrasse, Klatterstrasse and Enkereistrasse, which were the main streets until the end of the 19th century. When you arrive on Klatterstrasse you stand in front of the oldest surviving half-timbered house from 1529. Next to it is the house number 12 from the 18th century, which used to be a brewery. In his basement there was a pond (moat) from the weir that cooled the beer. Your walk finally ends at the castle rock and shows you Stolberg's landmark, the defiant medieval castle from the 12th century. It towers over the old town of Stolberg on a limestone cliff and looks back on 500 years of building history. You can visit the castle on a guided tour that lasts around 1.5 hours and get a better picture of the building and its history. Last but not least, take a look at the copper yards in the valley axis near the Vichtbach. The early modern courtyards are another character feature of the city. But you won't come across any uniform buildings, but rather look at very individual courtyards. In the pre-industrial residential and commercial complexes there are copper yards that resemble palaces or are reminiscent of simple craft workshops. You should have enough time to visit the old town, the castle and the copper yards so that you can see everything in a relaxed manner. Source: https://www.eifel.info/a-historical-altstadtkern

Stolberg's Old Town is one of the historic town centers of North Rhine-Westphalia and part of Oberstolberg in the copper town of Stolberg in the Aachen metropolitan region. The old town dates back to the city's origins and, together with Stolberg Castle, forms Stolberg's historic town center. The oldest streets and alleys are located near the castle. Several half-timbered houses in the late Gothic style have been preserved; the area is dominated by historic quarry stone houses made of dolomite limestone, whose window and door frames, corner blocks, and other supporting and decorative elements are made of bluestone. Over 100 buildings are listed as historical monuments, and numerous sculptures can be found here. Stolberg's oldest copper courtyards are also located here. The castle stands on a limestone rock. It dates back to the 15th century; a predecessor building dates back to the 12th century.

Beautiful medieval gate of the city of Jülich. Beginning of the pedestrian zone in the city of Jülich. From here you can stroll to the "Schlossplatz" or turn 180° and go to the bridgehead (Napoleonic fortress component) and visit it. The State Garden Show was held here in 1998.

one of the few pieces in Jülich that survived the 2nd World War (but is plundered from building sins in the 70s)

The description at the very end of the comments tells the basics about the castle.

The Jülich Citadel was once part of the Jülich Fortress and is the city's most important surviving architectural monument and one of the best-preserved fortresses in the bastion system in Germany. It was built in the years after 1545 as part of an ideal Renaissance city and is the oldest citadel north of the Alps.
