The success of the film "Tatort Falkenlay" inspired the idea of building a concrete replica of the main character, the old Lippi, for the film crew, the community, and guests. Apparently, it's located in the cave of events, and so the idea was born! What should it look like? He prefers to indulge in his favorite pastime: relaxing around the campfire! A friendly neighbor lent his face and hands to create lifelike casts. They constructed the upper body skeleton from strong wire. The legs were made from plumbing pipes and attached to the body. Now the hard work began. Everything had to be filled with scrap paper, wrapped several times, and then rewired. After dressing Lippi in old pants, they could begin the concrete work. Now the fine details of the body were modeled. The head, face, hands, and feet, which had been pre-cast, were placed in their designated places. The masterpiece was complete! With the kind support of the Kennfus volunteer fire department, Lippi then moved to his cave beneath the Falkenlay!

The Ulmener Maar tunnel connects the Ulmener Maar with the Jungferweiher Maar and is 120 meters long and 70 cm wide at its narrowest point. Different rock layers from the volcanic history can be seen. Display boards and paintings on the tunnel make the history very interesting. The tunnel was used to channel water from the two maars into the Ulmener Bach to the mills. Next to the tunnel, two drains and bulkheads are used to regulate the water level.

It's called the Ulmen Maar Tunnel and connects the Jungferweiher pond and the Ulmen Maar. The tunnel is finished and has been open to the public since April 25, 2023. It's turned out simply fantastic. A visit is definitely worthwhile. It's open in the summer months from 6 a.m. to 8 p.m. In winter, it's also open during the day. The circular and hiking trail around the Jungferweiher pond and the Ulmen Maar is wheelchair accessible. Cycling through the tunnel is prohibited, as the tunnel is only 70 centimeters wide at its narrowest point. You don't need to be claustrophobic. A visit to the Ulmen Castle ruins, with its fantastic view over the town of Ulmen and the Ulmen Maar, is also highly recommended.

The Ulmener Maarstollen was completed in 2023 and connects the Jungferweiher with the Ulmener Maar. Hopefully it stays as clean and beautiful as it was when I visited yesterday.
