About Svedudden Lighthouse
This red, cylindrical concrete lighthouse, standing 7 meters tall, was first lit in 1883. It features a white horizontal band and a lantern with a gallery. The light emits four flashes in white, red, and green every 12 seconds, indicating different sectors. It is situated on a point of land near Simpnäs, within Stockholm County. The site is accessible, but the tower remains closed to visitors.
Why it matters: Svedudden is essential for safe navigation in the passage between Björkö and Arholma, a narrow strait requiring precise guidance.
