Eis- und Schwimmstadion Köln

At its 1936 opening, the complex was still called the Eis- und Schwimmstadion an der Amsterdamer Straße — that street runs close to the narrower Lentstraße. The Kölner Eisklub was founded the same year, with its ice hockey, figure skating, and speed skating sections making the heaviest use of the venue. A roof wasn't added until 1964. The stadium hosted matches at the 1955 Ice Hockey World Championship and the German Figure Skating Championships in 1956 and 1978.

In 1972, the Kölner Haie's Bundesliga side broke away from Kölner EK and made Lentstraße their home, going on to win seven German titles there. In October 1998, the team relocated its home games to the newly opened Kölnarena (now Lanxess Arena) in Deutz, though training remained at Lentstraße for a time. In the venue's final years, the ice was used mainly for public skating.

When its timber-truss roof became dangerously close to collapse, the ice hall was closed on 15 March 2007. The entire complex was demolished between June and September 2008. A new facility broke ground in May 2009, featuring an indoor ice rink and pool, an outdoor pool, and an elevated ice track on the first floor. The new venue opened as the Lentpark on 1 October 2011.

Beyond sport, the site hosted other events: in 1992 over 15,000 people attended the Mayday rave here, and in 2004 an episode of the TV crime series Tatort was filmed inside the ice hall.
