Colosseum, Industrial architecture at Alleestrasse, Bochum, Germany.
The Colosseum in Bochum is a monumental supporting wall built from 2.8 million bricks reaching 16 meters high, marking the southern boundary of Westpark. The structure once formed the foundation of a large industrial facility and remains today as a striking remnant of brick and steel.
The structure was built in 1911 as part of the Martin-Stahlwerk steelworks and served the heavy industry until 1983. After production ceased, most buildings were demolished, but this wall remained standing as a witness to that era.
Steel sculptures by local artist Friedrich Gräsel display painted industrial pipes integrated into the arched facade. This art installation makes the industrial past of the site visible and tangible to visitors.
The square in front of the structure was renovated in 2010 and is freely accessible at any time for exploration. Visitors can walk around freely and view the wall from various angles, ideal for photography and casual walks.
Underground crawl spaces beneath the wall functioned as air raid shelters during World War II. These hidden rooms were part of a comprehensive protection system for the population of that time.
