In Jeleń, a district of Jaworzno city in Silesia, Poland, a residential house became infamous for poltergeist activity that drove several families to abandon the property. Residents reported escalating phenomena including loud noises in the walls and floors, furniture moving on its own, objects being thrown across rooms, and the sensation of being watched and touched by unseen entities. Multiple families moved into and then quickly out of the house, each reporting similar experiences. The case attracted media attention in Poland and was investigated by both paranormal researchers and Catholic clergy. The house's location in Silesia — a region with a complex history involving Polish, German, and Czech influences, plus extensive coal mining that has created underground tunnels and subsidence — has led some investigators to explore geological explanations. However, the consistency of witness reports across different families argues against simple structural causes. The Jeleń haunted house has become one of the most discussed poltergeist cases in modern Polish paranormal literature.
