About Griffith Island Lighthouse
This cylindrical stone tower, standing 20 meters tall, was built in 1858. It is situated on the northeast point of Griffith Island, off Cape Commodore, near the base of the Bruce Peninsula. The lighthouse features a lantern and gallery and emits a white flash every 4 seconds, with a focal height of 31 meters providing a geographic range of 15.5 nautical miles. A 1-1/2 story stone keeper's house, attached to the tower, has been in ruins since its abandonment in 1955. The lighthouse remains operational, though its remote location makes access difficult.
Why it matters: As one of the Imperial Towers designed by engineer John Brown, this lighthouse was important for guiding vessels through Lake Huron and Georgian Bay.
