The Kahlenberg lies in the Vienna Woods and is one of the most popular destinations for day-trips from Vienna, offering a view over the entire city. Parts of Lower Austria can also be seen from Stefaniewarte at the peak. Next to Stefaniewarte is a 165-meter high steel tower that serves as the transmitter for the ORF, the Austrian Broadcast Corporation. Two terraces are located on the mountain: one at a small church called St. Josef and one at a restaurant built in the 1930s by architect Erich Boltenstern. Parts of the restaurant and a nearby abandoned hotel have been torn down and replaced by a modern restaurant and MODUL University Vienna, a private university established in 2007, focusing on Social and Economic Development, in particular in the areas of tourism, information technology and public governance. The demolition was opposed by the local historical society and by some architects who believed the building was worth protecting. There is also a spiritual recovery center and a center for a Catholic reform movement, the Schönstattbewegung Österreich.
