Roaming around the area surrounding Aachen, we made a quick stop to see Castle Stolberg, a well kept 12th century in the Stolberg old town. It’s nowadays mostly used for medieval themed events and offers accommodation and a restaurant. There are some grand views of the area from the castle, and the nearby old town with the hills, valleys, and river, makes for a somewhat typical German atmosphere. There’s also a small handicrafts museum. Definitely not a must, but if you’re already driving through the region, this might be a good place for a stop.
