The distinguishing feature of the skyline at the Messe Berlin is what I like to call the Fake Eiffel Tower. The real name is the Funkturm Berlin, which was built as a radio tower in the 1920s and hearkens back to IFA's roots. The show was inaugurated in 1926 as a radio expo, before expanding to all types of electronics in later years. While it's no longer a functioning broadcast tower, there is an observation deck and a restaurant on the tower. It also acts as a crucial point of reference for attendees making their way around this gigantic maze of a building.
