A small hill fort in the shape of a cone located in Kochlowice (a district of Ruda Śląska), is one of the mysterious traces of the past in this part of Upper Silesia. The remains of the hill fort lie at the confluence of the small Kochłówka rivers and the Przykopa stream. According to archaeologists, from the thirteenth to the fifteenth century there were wooden buildings here. It is possible that the site was the seat of a certain knight or a watchtower on the border of the Silesian principalities.
