Gustaf Dalén lighthouse

The Gustaf Dalén lighthouse stands on the Baltic Sea coast and uses an acetylene gas system with automatic sun valve control. The structure works without human help and keeps the light running continuously through solar-powered mechanisms.

The lighthouse was built in the early 1900s and embodies the technological innovations of Gustaf Dalén, a Nobel Prize winner. His inventions transformed maritime safety across the world.

The lighthouse shows Swedish engineering skill through its AGA system, which changed how ships navigate at sea. Visitors see a monument to practical progress made by solving real problems in maritime safety.

The area around the lighthouse is easy to reach on foot and offers views across the coast. Visitors should be ready for changing weather since the location sits exposed on a headland.

The Dalén Flasher system uses just five percent of the fuel that traditional lighthouses needed. This efficiency meant distant lighthouses could run automatically without regular maintenance trips.
