Palais Hansen Kempinski Vienna
Planned and built by the famous Danish architect Theophil Edvard Hansen, it opened its doors in 1873. Hansen’s work (influenced by Greek architecture) can be seen throughout the city, as he also built Austria’s Parliament, Palais Epstein and Vienna Music Society (among others). While the building was originally designed as a hotel to be used for the 1873 World Exhibition, it instead housed offices and municipal departments.
Over a century later in 1997, the City of Vienna sold the building and the Kempinski Group opened it as a hotel in 2013.
While Palais Hansen Kempinski was already lit, it was using old, inefficient technology, so at the end of 2019, acdc was tasked with illuminating the façade.
