Biotürme Lauchhammer, Industrial heritage monument in Lauchhammer, Germany.

The Biotürme Lauchhammer is a group of 24 hollow cylindrical towers of reddish-brown brick, 22 meters tall, arranged in rows on a paved area. Each tower is open at the top with a thin metal rim; metal platforms with railings are attached near the top of three towers. A low white border with small fixtures surrounds the cluster.

The 24 towers were built in 1957 on the site of the lignite coking plant in north Lauchhammer-West and began operating in 1958/59. They biologically treated phenol-laden wastewater by trickling it over blast-furnace slag until the plant closed on 31 December 2002. Protected since 1996, they were restored from 2006 with EU regional funds and lignite remediation money, opening to the public on 17 July 2008 as an International Building Exhibition Fürst-Pückler-Land project.

The site's motto, "Castel del Monte der Lausitz", refers to the crown-like ring of towers. Since 2008 an exhibition building and a concert and theatre room have been available for public events, and in 2023 the grounds served as a filming location for Betterov's music video "Jil Sander Sun".

Visitors can climb one of the towers on designated days to enjoy views from observation platforms above the grounds. Allow time to explore the exhibition spaces and event venues integrated throughout the complex.

The towers were filled with blast-furnace slag, over which phenol-laden wastewater trickled to be treated biologically. In 2023 the grounds served as a filming location for Betterov's music video "Jil Sander Sun".
