About Fladen Lighthouse

The Fladen lighthouse, a cylindrical concrete tower completed in 1969, stands 26 meters tall on a shoal in the Kattegat sea. Its upper half is painted red and the lower half black. The structure features upper and lower galleries and a helipad on top, with its light positioned 24 meters above sea level. Emitting a white flash every 8 seconds, its light is visible for 14.1 nautical miles. This lighthouse replaced the lightship Fladen (Fyrskepp 29), which had served the station since 1892. The site is accessible to visitors, though the tower itself is closed.

Why it matters: Its construction in 1969 marked a transition from a century of lightship service to a permanent structure, enhancing safety in this busy sea lane. The lighthouse also holds historical significance as a successor to the lightships that once guarded this station.
