Swisscom-Sendeturm St. Chrischona is a communications tower built in 1980–1984 near Basel, Switzerland, on the territory of the municipality Bettingen, Basel-Stadt.
It was built as a replacement for a 136-metre (446 ft) tall lattice tower, which was erected at the site in 1962. This lattice tower was once a part of the famous Beromünster transmitter.
The tower is 250 m (820 ft) tall – a 98 m (322 ft) steel antenna on a 152 m (499 ft) concrete base – and not generally accessible for the public, although guided visits can be booked. Apart from television, FM radio and DAB transmitters, and microwave relays, the tower also contains meteorological instruments, two 100 m3 (3,500 cu ft) drinking water tanks, and a meeting/conference room near the top of the concrete structure.
