Ågesta Reactor

Sweden''s first commercial nuclear plant, carved into bedrock — it heated the Stockholm suburb of Farsta from 1964 to 1974

Buried deep in the granite bedrock beneath a hill in Ågesta, a southern suburb of Stockholm, the Ågesta Reactor was Sweden''s first commercial nuclear power plant. Construction began in 1957; the entire facility was blasted into solid rock — both for safety and because the surrounding granite served as natural shielding. Between 1964 and 1974 the reactor primarily supplied district heating to the Stockholm suburb of Farsta, with a small amount of electricity as a secondary output. This dual-use model was a pioneering experiment in civilian nuclear power at the time. After shutdown in 1974, decommissioning continued into the 1980s; the underground chambers still exist beneath the hillside. The site is not publicly accessible, but it stands as a quiet relic of a largely forgotten chapter in Swedish engineering history.
