About Parrio Lighthouse

The Parrio Lighthouse, an octagonal concrete tower standing 6 meters tall, was first lit in 1938. Its lantern room brings the focal height to 9 meters above sea level. The white tower exhibits two white, red, or green flashes every 6 seconds, with a geographic range of 10 nautical miles. It is situated on the southwest coast of Parrio island, roughly 1 kilometer northwest of the Russian border. Range lights were already in operation in this area by the 1920s, indicating a long-standing need for navigation aids. The lighthouse site is open to the public, though the tower itself is closed.

Why it matters: This lighthouse is essential for guiding vessels through the complex inside passage it guards, particularly in the sensitive border region.
