Even today, blocks of stone with Roman numerals and inscriptions can be found in the mine. It is believed that quarrying continued into the 3rd century, as a coin of Emperor Maximinus Thrax was found in the tunnel. Much later, in the 18th century, the search for ore and copper resumed using state-of-the-art blasting techniques, creating new tunnels approximately 114 meters deep. However, the main tunnel collapsed during this process. Source: https://eifelfuehrer.de/touristische-ziele/geschichtliche-zeugnisse/puetzloecher

The Roman copper mine "Pützlöcher," located between Kordel and Butzweiler, is one of the oldest in Germany and means "waterhole." Here, in the 2nd century, ores such as malachite and azurite were mined at a depth of 20 meters. However, these ores were not found in large deposits, so the Romans later focused on the nearby quarry. The stones from this quarry were used, among other things, for the construction of the Porta Nigra. Source: https://eifelfuehrer.de/touristische-ziele/geschichtliche-zeugnisse/puetzloecher

A nice resting place under a rocky outcrop that offers shelter even in a storm. The father's association, which celebrates its festivals here, has existed for 40 years.

The Porta Nigra in Trier, the Cologne Cathedral and the Reichstag in Berlin have something in common! The building blocks come from the same area near Butzweiler near Trier. "Pützlöcher" is the popular name for a Roman quarry in which the large blocks for the construction of the Porta Nigra were cut out of the rock. Previously, copper ore was mined here.⚒️

Well, when he comes down... :-D you're flat. It is impressive to take a rest underneath.

Sirzenicher Gorge is beautiful. You have to cross the creek several times. If that is too difficult, you can also choose the easy path nearby.

The Sirzenich waterfalls are always worth hiking to

Putzloch denotes a former Roman mine in which copper ores were mined and a quarry from which stones were extracted for the construction of the Porta Nigra: It looks wild here and it's worth exploring a little. If a visit to the mine shafts is still possible today by arrangement (as in the past), one would have to ask the Heimatverein Butzweiler. https://www.roemerpfad.de/index.php/9-sehenswuerdheiten https://www.eifel.info/a-roemisches-kupferbergwerk-puetzloecher
