Harsh Ore Mountains (Czech: Krušné hory): Mystery of a Nazi factory

„In the north-west corner of our country you will find deep forests, wild countryside and a romantic atmosphere. The destination of this trip is the premises hidden in the hills of the Ore Mountains. First, climb the Cross Hill (Czech: Křížový vrch), Tisovský Hill nicknamed Pajndl, where you can enjoy a great view. Then take a break at a place called Rolava, which is a large mining compound to which a prison camp was connected during World War II. A biking fantasy is the poetically named Izolátor (The Insulator) trail, which weaves its way through the steep slope of the hills above Nové Hamry. During your journey you will pass a former settlement called Chaloupky, which was displaced after the war and razed to the ground. Go on across the gorgeous plains of the Ore Mountains, past the Milíř Hill, and do not miss a vantage point called Nad Přebuzí, from where there is a great view of the large valley. And the place with the mysterious factory is now waiting for you. Sauersack. You will see a huge concrete monster with gloomy buildings. The atmosphere is very thick and you sometimes feel like you are in a horror film. Your head is full of questions waiting to be answered: were there really secret laboratories here? Did they carry out experiments on people here? Old resources are clear: tin was mined here and prisoners worked here. When World War II ended, the mine was closed down and has ever since been arousing the imagination of its visitors. If you are searching for an opportunity for biking in the wilderness with a flavour of adventure, this trip to the Ore Mountains will not be disappointing.“
