The Grüner Mühle is a water mill formerly used as an oil mill and paper mill on the weir below the Weidenhausen Bridge in Marburg an der Lahn on the edge of what is now the southern district. In addition to the "Grüner Tor" at the southern end of the street "Am Grün", the historic waterfront of Marburg with small houses right on the banks of the Lahn, this was the southern outskirts of the city before the city was expanded with the southern quarter that was created around 1880.

The mill was first mentioned in a document in 1248. Bishop Ludwig von Münster renounced his claim to the mill in 1320. Landgrave Otto I then handed the mill over to the Teutonic Order of Marburg . In 1496, however, he exchanged them with the landgrave for discounts .

Today the undershot mill wheel is still there, but no longer in operation. One of the buildings now houses a restaurant and several apartments. From 1583 or 84, the water of the Lahn was pumped up into a water pipe to a water reservoir at the Marburg Landgrave Castle above the upper town using a water art . In 1456 the new oil mill was built, in 1570 a paper mill for paper production .

Lahn weir Green weir

On the left a low Lahn weir south of a city gate and on the west bank a mill with 4 mill wheels arranged in a row directly on the river and ancillary buildings on the left. Further up the river to the right the late medieval Weidenhäuser Bridge and the houses of Weidenhausen in front of it. Two side arms of the Lahn, one of which flows around Weidenhausen in the historical view of the city, the second parallel to today's Lahn through the south of Weidenhausen, a smaller building on the weir, roughly at the level of the later millet mill.

The 73 m long green weir built between the former mill on the west bank and the Trojedamm with the millet mill on the east bank in the district of Weidenhausen dams the water next to the mill for the mill canal (called "Kupfer-Mühl-Wasser" in 1722), which here flows south parallel to the Lahn. The typical inclined weir made of block stones with weir widening in its building history and the extension by a stone pouring in the 1970s is to be supplemented by a fish ladder in accordance with the EU Water Framework Directive; a 2008 study preferred a bypass with a greater inlet depth. It stands on gravel with a foundation on wooden piles. In 2018, the city's plans were announced to expand the weir, which was in need of renovation, in one go by an expensive modernization for leisure traffic in the river and for visits to the (still natural) banks of the Lahn; However, due to the strong interference in the bank areas with tree felling in the Lindenhalballee on the Trojedamm, their scope is controversial, also because of the weir that characterizes the cityscape and silhouette (photo motif). Construction should only start after the Weidenhäuser Bridge has been converted; the city of Marburg allows citizens to participate in the design of the redevelopment for local recreation , nature and water protection, monument protection, tourism and other aspects. According to the assessment of the monument advisory board, this hydraulic structure with origins as a system from the Renaissance period (1553) is a cultural monument with historical significance and would be destroyed by demolition and subsequent reconstruction with a concrete core.

With floating leaves companies in the quiet upper hand above the Green weir and its faunal and floristic valences this section of the Lahn is at the mill, landscape planning one of the most attractive in the city and as a visual landscape conservation area in Marburg Lahn reported. From a fisheries biological point of view, there is an extremely valuable and species-rich animal population with barbel , grayling , river mussels and other flow-loving species at the base of the weir and the shallowly overflowing gravel banks in the underwater, with natural structures in this section of the river.
