Svampen, Water tower and tourist attraction in Örebro, Sweden

Svampen is a water tower in Örebro with a mushroom-shaped structure standing 58 meters tall. The building features an observation deck with views over Lake Hjälmaren and the city, along with a café inside.

The building was completed in 1958 according to architect Sune Lindström's design and replaced two older water towers in the city. This development marked an important step in modernizing Örebro's water supply system.

The name Svampen is Swedish for 'the mushroom', after the tower's shape. The top floor holds a café and a conference facility, and before the safety net was added the tower drew around 100,000 visitors a year. On World Diabetes Day in 2007 the tower was lit in blue.

Two lifts run up to the terrace, and an emergency staircase of 300 steps leads down. Since 2015 a glass enclosure has replaced the net cage around the viewing area. The tower is a designated building monument, so alterations are restricted.

In 1971 a copy of Svampen, 33 percent larger, was built in Riyadh at the request of Prince Faisal bin Abdul Aziz. Similar towers exist in Kuwait. In 2009 a model of Neptune was placed on the terrace's western edge, the endpoint of the 2.5 km Solar System in Örebro format.
