Green Pütz

from Wikipedia, the free encyclopedia
Well of the Eifel water pipeline

Green Puetz is the corridor designation of a flood plain in Urfttal in the district Nettersheim .

One of the spring taps of the Roman Eifel aqueduct is located here , which supplied the Colonia Claudia Ara Agrippinensium , ancient Cologne , with drinking water. The Mechernicher mountain Officials CA Eick pointed mid-19th century archaeological after that the Green Puetz was the extreme point of the Eifel Aqueduct. The source catchment and the adjoining canal up to the railway embankment are now in operation again. However, the water flows behind the embankment, i.e. H. still in the valley, in the Urft.

There is a parking lot for visitors to the Grüner Pütz near the former Gronrecht mill, also known as the "Rosenthaler Mühle".

Eifel aqueduct

The spring connection consisted of an 80 m long seepage water pipe, which collected the spring water at the foot of the valley slope and passed it on to a well room, in which the water was clarified before it was transported on to Cologne in the canal. The spring version was only excavated by W. Haberey in 1952 . The restoration took place in 1975.

The seepage water pipe consisted of dry masonry, which was permeable to water on the slope side and was only sealed with clay on the outside of the cheek facing the Urft , so that no water was lost and no river water could penetrate the Urft. The bottom of the seepage water pipe consisted only of gravel . There were sandstone slabs on the line. The width of the seepage water pipe was 40 to 45 cm, the height 70 cm to 100 cm, increasing towards the well.

The almost square foundation of the well room consisted of sandstone blocks and had the clear dimensions 1.93 m × 1.86 m. The bed, made of gravel, was 15 cm deeper than that of the seepage water pipe and the canal beginning on the other side of the well. On the mountain side, there were also two openings in the well room through which spring water could flow in. In the well room, the flow rate of the water slowed down so that impurities could settle on the floor. Like the seepage water pipe, the well room was also provided with a 30 to 40 cm thick clay seal on the side facing the Urft. Today's reconstruction of the well room has an opening on the valley side, which did not exist in antiquity, through which one can see how the structure works today. Semicircular capstones closed it off at the top. A corresponding corner piece with a Medusa or Gorgon head was found in the well room during the excavation .

The canal, which transported the water collected in the well room to ancient Cologne, consisted of a channel made of cast concrete on which there was a vault made of limestone and greywacke, which sealed the pipe at the top. The inside of the canal was sealed with reddish water plaster and had a clear width of 50 cm and a clear height of 90 cm.

The seepage water pipe, the well room and the adjoining canal are stations 1 and 2 of the Roman canal hiking trail from Nettersheim to Cologne, which was renewed in 2012 .

Roman road Trier – Cologne

Above the parking lot at the former Gronrechtsmühle, a footpath runs in a serpentine shape on the southern slope of the valley on the former route of the Roman road Trier – Cologne (Agrippastraße).

It is part of this Roman highway from Trier via Jünkerath , Marcomagus and Zülpich to Cologne. After the ancient traveler coming from Zülpich had crossed the Urft, he drove this serpentine (50 ° 30'40 "N; 6 ° 36'45" E) , some of which still exists as a ravine today, and came to the Nettersheim-Marmagener Plateau and finally reached the Görresburg behind the Schleifbachtal near Nettersheim , which was at the beginning of a Roman vicus (probably with the name Marcomagus).
