The Ulmen Maar lies 420 meters above sea level today, covers an area of 5.5 hectares, and is 36 meters deep. The bubbles at the maar's edge demonstrate that volcanism is still active. They bear witness to a turbulent past—but rest assured, there's no eruption in sight! A wall of various rocks and ash, up to 20 meters thick, surrounds the cone. For those interested, these testimonies to this explosive past are beautifully displayed in St. Matthias Church. This unique wall, with its different colored layers and rounded inclusions, is worth seeing for more than just geologists. The slopes of the maar basin are covered with a beautiful forest, which can be explored on a circular walk. A detour to the medieval castle ruins, from which the Crusaders once launched their campaigns, is recommended. The view from the crater rim over the maar and the Eifel beyond will take your breath away. Whether after a sweaty hike or a long drive, the blue of the Ulmer Eifel lake is all too tempting in summer. However, bathing in the maar is prohibited because it is designated as a nature and water protection area.

The lower castle has completely disappeared. You can still see the beginning of the ring that connected the lower castle and the Ulmen city wall, a two-story outer wall of the palace, as well as a cistern and some foundation walls of other buildings. The old part of Ulmen Castle was built around 1074 AD and likely rests on the remains of a Roman settlement. In the Middle Ages, Ulmen Castle was further expanded and divided into the upper castle, whose remains of the walls still exist, and the lower castle, which extended to the banks of the maar river. Two knightly families lived in the castle, which is believed to have never been attacked or destroyed until 1673 due to its size. Only the Sun King's troops succeeded. It was rebuilt, but fell again in 1689 during the War of the Succession. However, Ulmen Castle was also rebuilt this time, with only the city wall being abandoned. With the invasion of Napoleon's soldiers, Ulmen also became French and later Prussian. The empty castle, whose last descendant died in 1801, was auctioned to a merchant from Cochem, who sold it as a quarry. When a devastating fire burned Ulmen to the ground in the 19th century, the residents of Ulmen rebuilt their houses with stones from the castle. That's why you can still see a coat of arms on some of the stables today. It wasn't until the early twentieth century that Ulmen Castle was declared a listed building and became the property of the municipality of Ulmen. The castle is always freely accessible.

The Ulmener Maar is small but beautiful. Located in the middle of the Eifel and in the middle of the city, it is a wonderful destination. You can easily combine a walk around the maar with a walk around the neighboring Jungferweiher. Both have recently been connected by the Ulmener Maar tunnel, which runs under the A 48 motorway.

The egg-shaped ejected particles are 6 cm or larger and deform the layers of earth when impacted. They are clearly visible here on the rock walls.

A visit is worthwhile both in summer and in winter. However, the Ulmener Maar is a nature reserve, which is why bathing is strictly forbidden here!

When you think of Nürburg, you only think of fast cars and tight corners? Then you're not familiar with the castle ruins of the same name. Nürburg was founded before 1166, probably by the Counts of Are. Characteristic slate-covered conical roofs mark the silhouette of the castle, visible from afar. Not only the view from the mighty keep is worth a visit, but also the impressive remains of the former castle complex, which was expanded in several so-called "growth rings." You can find more detailed information about Nürburg here: https://kulturerbe-eifel-mosel.de/nuerburg

The Nürburg is the highest castle in Rhineland-Palatinate (676.5 m above sea level). It was built on a basalt, weathered volcanic vent. The basalt rock gave the mountain and the castle their name: Mons Nore, the black mountain. He also supplied the building materials for the castle. When the weather is clear, the keep (39 m high) offers a fantastic panoramic view of the entire Eifel, but also of the heart of the “Green Hell”, the Nordschleife, which winds its way through the woods around the castle.

The upper castle was built on a slope above the Ulmen maar, while the lower castle (also called lower castle) was adjacent but below it. The exact time of construction is not known, but it is assumed that the upper castle was built around the year 1000. It was first mentioned in a document in 1074. The ruins of the upper castle are owned by the municipality of Ulmen and in 1913 were listed as a historical monument. It is freely accessible and there are regular events on its premises, including an annual medieval market on the last weekend in June. Source: Wikipedia
