The Melbtal is a forest-like, wooded valley of the Melbbach or Engelsbach in Bonn . It runs between Ippendorf , Poppelsdorf and Venusberg from the Waldau to the Melbbad . The valley, lined with footpaths on both sides, has been a designated nature reserve since 2013 .
The name Melb- is interpreted as Celtic origin and is supposed to mean clay , the name Engelsbach is derived from a former monastery.
Attractions
In the lower part of the valley, only separated from the Melbbad by a corridor, is the Melbbrücke , a historic brick bridge from 1842. Other special features are the Jufferetrepp or Juffeletrepp (Jungfrau staircase), remains of an electoral English garden and the Troschelstein. In spring there are numerous early bloomers such as wood anemones .
Landslides in the Melbe Valley
Due to a geological peculiarity, there are repeated ground tiles and landslides . The lower soil horizon is water-impermeable clay , the upper is made of water-permeable loam , therebetween there is an approximately 5 cm thick swellable brown coal layer , which can act as a lubricant. In the 1960s, houses slipped into the Melbe Valley. Every year some older trees and their root plates fall over the stream. There is hardly any wood removal due to inadequate paths.
The protection and benefit initiative chaired by Wolfgang Alt , which represents the interests of the Melbtalan residents, was able to partially prevent the controversial closure of paths.
Melbtalwind
The so-called Melbe valley wind , which flows through the valley as a nightly cold air drain, has a certain significance for the climatic conditions in the center of Bonn, as an extension of the valley under Elector Clemens August presumably carefully laid out fresh air aisle along Clemens-August-Straße and Poppelsdorfer Avenue exists. However, this was largely closed again in the 20th century with high-rise buildings. The temperature reduction generated by the Melbtal wind in summer amounts to a maximum of 3 ° C in the foot of the slope, a maximum of 2 ° C in the vicinity of the Poppelsdorfer Schloss and 1 ° C in the lower part of Poppelsdorfer Allee, while in the city of the railway line on the left bank of the Rhine no more temperature decrease can be determined (measurements in the years 1976–1984).
Poem by Pirandello
The Italian poet and Nobel Prize winner Luigi Pirandello (1889 to 1892 for doctorate and then as a lecturer in Bonn) and his Bonn lover Jenny Schulz-Lander (later emigrated to Mansfield, USA ) wrote a poem about the Melbe Valley:
And in the song you are
granted eternal spring,
you woody valley of the strict Melb!
...
And you, between new flowers,
between never-withered grass,
sing about your eternal descent
into the plain,
oh hidden, quiet Melb,
oh happy soul of the valley,
secret picture of the time that
does not rest.
(From: Pasqua di Gea (1891), Part IX)
