Kahlenberg Transmitter

The Kahlenberg Transmitter is a broadcasting facility located on a northeastern hillside in Vienna, Austria. The structure consists of a 165-meter steel tube mast with technical rooms that broadcast radio and television signals across Vienna and the surrounding regions.

The facility began operations in 1953 with an antenna mounted on an existing tower, followed by a 129-meter lattice steel mast installed in 1956. The current steel tube mast was constructed in 1974 to replace the earlier structures.

The transmitter was designed by architect Gustav Peichl and demonstrates how technical requirements can be combined with thoughtful design. Its presence on the hillside has become part of how people experience the Vienna landscape when visiting this elevated location.

The site can be reached on foot via hiking trails that connect through the surrounding area. The facility itself is not open to visitors, but it can be viewed from outside and offers views across Vienna from this elevated location.

The hill where the transmitter stands was a key location during the 1683 siege of Vienna, serving as a strategic position for defenders. This historical significance gives the site importance beyond its modern broadcasting function.
