About Tröskeln Västra Lighthouse

Tröskeln Västra was a steel lighthouse built in the 1980s, standing 20 meters tall with a focal height of 26 meters. It featured a red tower with a single white horizontal band and a helipad on top, sharing its design with the Armbågen and Solovjeva lighthouses. Its light emitted a white flash every 20 seconds, visible for 14.5 nautical miles. This structure was located about 6.5 kilometers northwest of the former Armbågen lighthouse. Its operational life concluded in 2000 following a collision with a ship, leading to its demolition. A buoy now marks the location.

Why it matters: The destruction of Tröskeln Västra by a ship collision in 2000 highlights the risks present in shipping lanes and the need for reliable navigational aids.
