The first blast furnace on the Polish land was located in Bobrza, a small place in Kielce Powiat (the second level of Polish administrative division), in the 17th century. In 1824, at the distance of about 1 km, a new blast furnace plant was situated at the foot of a high slope.
It was then that huge retaining walls were erected. They were 500m long and 5m thick, and in some places their height reached 15m. Some ore storehouses, coal stores, ore roasting furnaces, a settlement and a water system were set up on the premises of the factory. The further development of the place was stopped by a flood and the outbreak of the November Uprising. Today, one can admire the remains of the blast furnace plant, the settlement and the mentioned retaining wall.
