The Winter-Badeschiff is a temporary construction which converts the Sommer-Badeschiff, a swimming pool floating in the river Spree into a sauna during the winter months. The Winter-Badeschiff has been opened for the first time in 2005. It is being dismantled at the end of every winter season to make way for the Sommer-Badeschiff.
Created from a converted cargo ship, the Badeschiff first opened in the summer of 2004 as a multidisciplinary art project organized by the initiative Stadtkunstprojekte (City Art Project Society) of Berlin. The sunken hull of the transformed vessel now offers a pristine 8 x 32 meter pool. Resting almost level with the Spree's surface the design gives one the sensation of swimming in the river itself with the city skyline as a dramatic backdrop. An open-air recreational complex in the warm months, the curving translucent shelter and saunas were added, under the direction of architect Gil Wilk, making the Badeschiff suitable for winter use.
