We’ve all seen the big concrete sewer tubes waiting to be installed during construction work, and now Das Park gives the opportunity to stay in one of these tubes. Each weighs 9.5 tons and needs little up-keep, just a coat of varnish to help keep the moisture from cracking the cement. Austrian artist, Thomas Latzel Ochoa, lends his touch to the inside of the tubes to make them a bit friendlier. The concrete stays cool on the inside and makes for a nice summer retreat. Das Park is open from May to October, and the rates are on a “pay what you think the stay was worth” type of system.
