Aqua Dome is a 140-room, four-star-plus hotel and spa complex in Tirol Therme Längenfeld, the Tyrolean Alps in Austria. The altitude must have had an effect on the planners and designers because the place is out-of-this world heavenly.
The services are impressive and the facilities absolutely beautiful although somewhat counterproductively named with words too difficult to pronounce unless you speak German. The dome-ceilinged, glass-walled thermal spring hall Ursprung (Origins) is the main indoor area with two pools and a huge waterfall. From there, you swim via two canal pools to the amazing outdoor area, Talfrische (Freshness Valley). With its illuminated structures and steaming vessels it resembles the potion-making lab of a gigantic but friendly sorcerer. The two canals lead to a cone-shaped illuminated tower. From there you proceed to the three bowl pools that look like gigantic martini glasses. Bobbing in one of these eight-metre-high bowls that are 12 to 16 meters in diameter, you can gaze upon the Alps and contemplate your good fortune.

Aqua Dome is located about 70 kilometers from Innsbruck and 180 kilometers from Munich in Längenfeld in the heart of the beautiful 67-kilometre-long Tirolean Ötztal valley known as a thermal springs area since the 16th century. Aqua Dome’s 3000-year-old, 40-degree Celsius sodium-chloride-sulphate-sulphur thermal waters flow from this ancient valley.
Aqua Dome was designed by Jacques Herzog and Pierre de Meuron. They are the 2001 recipients of the Pritzker price, the highest honor in architecture (also bestowed on Frank Gehry and Rem Koolhaas, among others) and have also designed the new Tate Gallery in London, Prada Tokyo and the Beijing National Stadium for the 2008 Olympics.
The Aqua Dome is Austria’s largest tourism project of recent years. It has revitalized tourism in the entire area, long known for fabulous hiking, skiing, mountaineering and white water rafting.
