The Kaknäs tower (Swedish: Kaknästornet) is a telecommunications tower located at Ladugårdsgärdet in Stockholm, Sweden. The tower is a major hub of Swedish television, radio and satellite broadcasts. It was finished in 1967, designed by architect Bengt Lindroos, and the height is 155 metres (509 ft) or 170 metres (560 ft) with the top antenna included. For a few years Kaknästornet was the tallest building in the Nordic countries until Näsinneula was opened in Tampere, Finland in 1971. It was surpassed in 2005 by the Turning Torso in Malmö. The tower is owned by the national Swedish broadcasting company Teracom. Its name comes from the ancient name of the area, Kaknäs.
The tower used to be open to the public, with an information centre and gift shop, indoor and outdoor observation decks as well as a restaurant, but has now been permanently closed to the public since 2018 on the grounds that the security repairs would have become too expensive. It was later revealed that the real cause is the threat of foreign intelligence. The fear is that a foreign power would seek to take control of important communication lines and systems of society. According to Swedish television, the Swedish security police have stated in a report in 2017 that the number of foreign intelligence companies has increased and the tower will be closed due to the report.
It is since December 2019 forbidden to photograph, copy, measure or describe the tower without permission.
