Wananas, Swimming center in Herne, Germany

Wananas is a swimming and leisure pool complex in the Wanne district of Herne, opened in December 2016. Its leisure pool holds a 380 m² basin with a 65-metre tube slide, a wide slide, a current channel, a grotto and a climbing wall, plus a 10 × 8 m outdoor pool. The sports pool has a 25-metre, five-lane competition pool with a 1-metre springboard and a 3-metre tower.

The first Wananas opened in 1994 on the site of the Freibad Wanne outdoor pool, which had operated from 1966 until its closure in 1992. On 10 November 2011 a technical defect caused a major fire that destroyed the leisure pool completely; it had counted around 3.5 million visitors. Construction of the replacement ran from February 2015 to November 2016, with a pre-opening on 25 November 2016 and public bathing from 27 December 2016 at a cost of 15 million euros.

This facility serves as a meeting point for the community and is used by schools, sports clubs, and recreational swimmers throughout the year. People of different ages gather here to train or simply spend time in the water together.

The sports pool opens to the public early on weekday mornings and at weekends; at other times it serves Herne schools and clubs. The course pool has an adjustable floor, and the 50-degree textile sauna in the leisure area is meant for beginners. The outdoor pool measures 10 by 8 metres, beside a lawn and two playgrounds.

The name Wananas is a portmanteau of Wanne, the Herne district where the pool stands, and the tropical fruit Ananas (pineapple). It was chosen and awarded after a public call for suggestions from Herne residents. The earlier pool of the same name, opened in 1994, drew around 3.5 million visitors before a technical defect caused a major fire on 10 November 2011.
