About Arnprior Island Lighthouse

The Arnprior Island Lighthouse is a white, cylindrical concrete tower standing 4 meters tall, with a red band near its top. Built in 1973, it replaced a previous structure, continuing a long tradition of maritime guidance. The lighthouse emits a white flash every four seconds from a focal height of 7 meters, visible for 9.3 nautical miles. It is uniquely situated on the concrete pier of the original lighthouse, adapting the older foundation for modern use. The site is open to the public, but the tower itself is closed to visitors.

Why it matters: This lighthouse is essential for guiding vessels safely around Arnprior Island and through local shipping lanes. Its placement on the original lighthouse's pier highlights the continuous need for a navigational aid at this location.
