Klangturm, Observation tower in St. Pölten, Austria
Klangturm is a 77-meter-high observation building in St. Pölten featuring three prominent steel spheres and a glass structure that reflects light across the governmental district. The structure includes an observation deck at 47 meters and interior spaces used for rotating exhibitions.
The tower opened in 1997 as part of St. Pölten's new governmental district, designed by architect Ernst Hoffmann to represent imagination within administration. It marked a turning point in the city's development and helped establish St. Pölten as the modern capital of Lower Austria.
The tower serves as a venue for art installations and live performances that draw both locals and tourists into the governmental district. Inside, rotating exhibitions and events throughout the year make it a gathering place where contemporary culture meets everyday city life.
Visitors can reach the observation deck using a panoramic elevator or by climbing 280 stairs to enjoy views across the Lower Austrian landscape. The best time to visit is on clear days when visibility across the countryside is greatest.
The structure required 650 tons of steel and three massive spheres about 6 meters in diameter and weighing nine tons each, which completely shape the tower's appearance. This extraordinary construction makes the building an unmistakable landmark of the city.
