The Blattenpass (formerly also Plattenpass) is located in the Swiss canton of Basel-Landschaft and was an important transition in the Blauenkette until the 18th century.
location
From Aesch im Birseck the access to the pass leads through the Klus up to the Blatte, where at an altitude of 577 m above sea level. M. is the culmination point of the once important Blattenpasses. From there, the path leads down into Laufental to Zwingen. The pass is not passable by motor vehicles, but offers hikers and cyclists a field of activity.
history
Since the river Birs in the Chessiloch between Grellingen and Zwingen winds through rocky erosion and a spur of the blue, the passage in the valley floor for a long time was impassable. Therefore, over the saddle at Blattenpass an important traffic route was created, which connected the Birseck with the Laufental. Even the Romans used this transition, and the old Roman road became the main route between the Alsace / Rhine plain and the Jura.
In the Klus of Aesch emerged in the Middle Ages on the way to the pass also some castles whose ruins are still partially well preserved: (ruin Frohberg, ruin Schalberg, ruin Engenstein, ruin Münchsberg), continues to follow in 1.9 km distance as the crow flies Pfeffingen ; These all bear witness to the importance of this connection and the attraction of this region.
It was not until 1730 that the obstacle in the Chessiloch could be overcome, and the connection over the mountain quickly lost importance. With the construction of the Jura Railway in 1874, the pass was then completely forgotten.
At the top of the pass stood a tavern whose location is still recognizable on the basis of remains of foundations. It was demolished at the direction of the Bishop of Basel, as it had become a dive bar.
