About Pirköyri Lighthouse

A 7-meter square wooden tower, painted white with an orange lantern, marks the waters off the southwestern shore of Pirköyri island. This structure, standing 6 meters above sea level, emits a flashing white, red, and green light on a 3-second cycle. The lighthouse guides vessels leaving the nearby port of Kotka, situated 1.3 kilometers away. Its design includes a lantern and gallery. While the island site is accessible, the tower itself is closed to the public.

Why it matters: The lighthouse is essential for safe navigation from Kotka, providing a specific narrow white light sector to precisely mark the channel for departing vessels.
