The Pyramidenkogel tower, the tallest wooden tower in the world is tall and rests atop the Pyramidenkogel mountain in Carinthia, Austria. Another observation tower sits atop the Gallitzinberg forest which in 1956 replaced an older steel tower that had been erected in 1899. Therefore, the present tower is still colloquially known as the Jubiläumswarte (jubilee tower). Its topmost platform, above ground, offers an impressive panorama of Vienna.
