Nachtigallental Trail

de.wikipedia.org/wiki/Nachtigallental_(Siebengebirge)
geography
The Nachtigallental is a Siefen (Kerbtal) valley, starting from the eastern edge of the old town of Königswinter in a largely south-southeast direction along the Drachenfels (321 m above sea level) on the south side and the Hirschberg (257 m above sea level) on the north side to the Siebengebirge. It is traversed by the Hitelbach (also "Mennesbach"). . . . The ridge of the Drachenfels, which runs along the Nachtigallental, is also known under the name Saurenberg or Saurer Berg, which was mentioned as early as 1715 and goes back to a field name.
The nightingale valley is one of the ascents to the Drachenfels used as an alternative to the donkey trail.

Story
The valley was originally called Mennessiefen and was traversed by a narrow bush forest path to below the castle courtyard. To stimulate tourism in Königswinter, which had declined in the middle of the 19th century, the path leading through the valley was expanded as a first measure on the initiative of the then mayor August Mirbach from donations from Königswinter citizens by 1861 to a promenade described as "shady and romantic" and at the same time the Valley renamed Nightingale Valley. In 1867, also financed by donations, the construction of the Oberweingartenweg followed along the south-west side of the valley towards the Drachenfels.

buildings and sights
-Altar table
On June 28, 1925, a forest service was held at the entrance to the nightingale valley as the beginning of the local parade to celebrate the millennium of the Rhineland. A stone altar table was permanently erected at a fork in the road about 150 meters from the entrance to the valley, which was last used as a step for the parish church of St. Remigius had served and still goes back to its predecessor church from 1779.
-Ostermann monument
-Wine cellar (I somehow overlooked it, also not listed as a highlight in Komoot)
In the Nachtigallental there is a refrigerated cellar of the winegrowers' association, which was let into the mountain in 1867. It has a round arched gate towards the valley, which is supported at the top by a basket arch that was cast later. The keystone shows a painted coat of arms with grapes and the initials W.D.H., on the archway there is a heavily weathered inscription. Access to the cellar is guaranteed by a double-leaf iron gate, which has been open for years.
-Hell Tuff

A nice way to the Drachenfels. Up to Drachenburg Castle there is a steady, slight ascent, always along the babbling brook. There is also significantly less going on here than on the path next to the cog railway.

Beautiful romantic hiking trail. When you come in from Königswinter it is like diving into another world
