RWTH Aachen Week 5: Wanderungen in der Natur
1 - Lousberg After my German lesson on Monday, my classmates planned to go jogging at Lousberg in the evening, so I naturally went along. Lousberg is a gentle wooded hill right on the edge of Aachen's city center, one of the city's most beloved green spaces and a popular spot for locals to walk, run, and unwind. The paths wind through a mix of open meadows and dense tree cover, with the city visible through the treeline in places, making it feel surprisingly removed from urban life despite being so close. The weather was actually really cold in the morning, but by the time I got there for the jog it was super sunny and perfect for some exercise. It is about a 15 minute walk from the Ponttor bus stop.
2 - Some cool stuff I saw
Walking to the Lousberg park entrance, I passed by the massive Lindt factory right here in Aachen. Apparently there is a store there too and tours can be booked, so I will definitely go check it out sometime. Halfway through the run I also came across a really interesting circular tower in the middle of the forest called the Drehturm Belvedere. It is a historic rotating observation tower built in the early 20th century, designed so that visitors could be turned to face different panoramic views of the surrounding landscape without having to move themselves. The architecture is quirky and charming and it looks genuinely cool, so next time I want to go inside and see it properly.
Near the end of the route there is also the Tranchot-Obelisk, a stone monument erected in honour of Jean Joseph Tranchot, the French cartographer who conducted one of the first systematic topographic surveys of the Rhineland in the early 1800s. The obelisk marks one of his key surveying points, and the view from the platform up there is amazing. There are also goats grazing on the slopes below, which was a pleasant surprise.
3 - Investigating a mysterious art piece
There is also an interesting installation nearby, something like a lever with a red knob and a massive brightly coloured nuclear warning sign. I tried reading the German text and gathered it had something to do with a Belgian nuclear power plant, but I could not quite figure out what it was saying. I looked it up online and could not find any specific information about the installation itself, except that the city of Aachen has been in a long-running dispute with Belgium over the Tihange nuclear power plant, which many Aachen residents consider a genuine safety risk given how close it sits to the city. I will investigate further what this interesting piece is actually about.
I also saw a statue about the devil lending money to build the Aachen cathedral and reap the soul of the first living being to enter it once its completed but the devil was tricked by the people. There's also pictures at the Lindt factory store, a tiny library out in the wild, and extremely beautiful streets.
4 - Dreilägerbachtalsperre, Roetgen
We went hiking again, this time starting at a dam called Dreilägerbachtalsperre after a 1.5 hour bus ride from Aachen. The trail runs through a forest area called Hasselbachgraben, which sits within the Eifel nature park. The landscape here is quintessentially northern European forest: tall stands of beech and oak lining narrow paths, the ground carpeted in ferns, and small streams threading quietly through the undergrowth. The canopy is dense enough that the light filters through in long soft shafts, and the whole area has the kind of deep quiet that makes you want to slow down.
I really loved it because the forest floor was thick with moss, with tiny water ponds scattered in between since it had just rained, and everything smelled incredibly fresh. The ground was squishy underfoot, the whole place so serene and beautiful that it genuinely felt like a frame from a Ghibli film. It reminded me of Princess Mononoke.
5 - Kuhberg
At the end of the hike there is a small town called Kuhberg, which literally means "cow mountain," and it earns the name. There are small hills dotted with cows, and the houses are super modern and well kept, like some kind of utopian countryside community. Families put cow decorations outside their homes and every single house seems to have at least one, with cow statues and models appearing on rooftops and in gardens as well. There were also lots of RVs and camper trailers parked around, including tiny ones. Theres also a part of the Westwall from ww2 remaining, filled with concrete "Dragon's teeth" intended to stop the allied tanks advancing into rhein-ruhr region. It didn't work, and Eisenhower ordered them to be dismantled after the war, though there are still tens of kilometers of the westwall remaining. I fell asleep on the bus back to Aachen.
This was a peaceful week and not much happened besides lots of hiking. An easy 15k steps daily. Will update next week as we approach the halfway point of the research program!
