Duodde Fyr

Dueodde had a sand problem long before 1962. The dunes at Bornholm’s southern tip are made of some of the finest sand in Europe, fine enough that locals shipped it off for use in hourglasses and the Danish royal family reportedly used it as blotting paper. It is, in other words, exceptional sand. It is also extremely mobile sand, and the island’s two original lighthouses at Dueodde, the Nord and Syd towers, spent decades getting steadily buried by the very dunes they were meant to watch over.

Denmark’s solution, in 1960, was to stop fighting the sand at ground level and build over it instead. The new lighthouse rose on 14-meter-deep reinforced concrete piles, a foundation substantial enough to survive two harsh winters of construction, topped by a 47-meter tower that became, on its commissioning in August 1962, the tallest lighthouse in the country. The old Nord and Syd towers remain standing nearby, retired and closed to the public, presumably still negotiating with the dunes.

The new tower runs a Fresnel rotary lens transplanted from the old Nord lighthouse, throwing three white flashes every ten seconds out to a range of roughly 35 kilometers, guiding ships clear of Bornholm’s southern tip and the shoals beyond it. Visitors willing to climb the 196 steps get a panoramic reward: the full sweep of the south coast, the dune field, and the Baltic beyond, assuming the weather agrees to cooperate.

The old lighthouses tried to outlast the sand. The new one just got out of its way.
