Kolbermoor Cotton Spinning Mill

Before the construction of the cotton mill, the Mangfall had to be straightened over a length of 2.7 km, an equally long works sewer had to be built and the Mangfall wilderness had to be cleared and leveled. Construction of the factory began in March 1861. At the same time, six residential buildings, two bridges and a connecting road from the country road to the Kolbermoor train station were built between Mangfall and the canal. On January 2, 1863, operations with 11,000 spindles began in the six-story main building. A year later, 41,000 spindles were working to manufacture yarn. On November 26, 1898, the spinning mill was destroyed within a few hours. At 8:30 in the morning, fire broke out on the fourth floor of the main building. The cause was never completely cleared up. With the amount of flammable substances available, the fire spread quickly, so that all attempts to nip it in the bud were unsuccessful. Rescuing the six-story main building was out of the question.
Despite the fire and enormous financial burdens, the spinning mill decided to rebuild, which was completed in 1899.

Before the cotton spinning mill could be built, the Mangfall had to be straightened over a length of 2.7 km, a factory canal of the same length built, and the Mangfall wilderness cleared and leveled. Construction of the factory began in March 1861. At the same time, six residential buildings, two bridges, and a connecting road from the country road to the Kolbermoor train station were built between the Mangfall and the canal. On January 2, 1863, operations began in the six-story main building with 11,000 spindles. One year later, 41,000 spindles were in use to produce yarn. On November 26, 1898, the spinning mill was destroyed within a few hours. At 8:30 a.m., a fire broke out on the fourth floor of the main building. The cause was never fully determined. Given the amount of flammable materials present, the fire spread quickly, so that all attempts to nip it in the bud were unsuccessful. Saving the six-story main building was no longer an option.
Despite the fire and enormous financial burdens, the spinning mill management decided to rebuild it, which was completed in 1899.Source and further information
