Volkspark Humboldthain is a public park in the Gesundbrunnen neighborhood of Berlin, Germany. The landscape park covers 29 hectares and was created between 1869 and 1876. It is notable both for its 19th-century design by landscape architect Gustav Meyer and for the remains of a World War II Flak tower integrated into the terrain as the rubble hill Humboldthöhe.^[1]

Work on the park began on 14 September 1869, the centenary of Alexander von Humboldt's birth; completion followed in 1876. The original concept by city garden director Gustav Meyer combined broad lawns, educational plantings and promenades typical of Berlin's 19th-century Volksparks.^[1][2]

Between October 1941 and April 1942, heavy flak structures (combat and command towers) were constructed in the park as part of Berlin's air-defense network. Building was around the clock with up to 3,200 workers, including foreign laborers and POWs.^[3] After 1945, the command tower was demolished and buried; the northern tower was only partially demolished (nearby rail lines limited blasting). The site was reshaped with large volumes of rubble to form today's Humboldthöhe.^[1] Contemporary reporting also recounts the postwar blasting attempts and their limits.^[4]

From the late 1940s to early 1950s the grounds were reconstructed as a public park. A formal rose garden (Rosengarten) was laid out on the former church site and remains a key feature of the southern section.^[2]

Informal urban explorers dug their way in and noted a fatal fall inside the Humboldthain bunker in 1982, underscoring why access today is controlled and guided.^[5] In the early 2000s, blocked passages were cleared and routes were secured inside the Humboldthain tower.^[6] Guided visits have since run seasonally, typically April–October; three of the tower’s seven floors are shown, after volunteers removed over 1,400 m³ of debris across 8,000+ hours of work, with helmets required and a 90-minute route designed to avoid disturbing hibernating bats.^[7]

• Bat hibernation site: The interior hosts several bat species in winter; it is one of Berlin's larger winter shelters for bats.^[2]
• Bunker tours: Regular guided visits to multiple levels of the flak structure.^[7]
• Humboldthain Club: In May 2013, the Club opened inside the station building at Hochstraße 46, next to the park. Operator Constantin Boese launched the venue with a four-day opening party on the second weekend of May.^[8][9]
• Humboldthöhe: Rubble hill incorporating remains of the northern flak tower; the tower was left standing in part to protect nearby rail lines during demolition.^[1]
• Climbing walls: The outer bunker walls are used as a sport-climbing facility operated by the German Alpine Club (DAV).^[10]
• Rosengarten: A formal rose garden; around 15,000 roses are arranged in box-edged beds and pergolas.^[11]
• Sommerbad Humboldthain: Outdoor pool complex with a 50 meter pool, slide, paddling pool and sunbathing lawns.^[12][13]

The park is treated as a historic garden monument within Berlin's inventory of protected green spaces and is maintained by the district of Mitte.^[2]

The park borders the Berlin Gesundbrunnen station (S- and long-distance rail), and is also served by local bus routes.^[2]
