Name and Location

The Porphyry Island Lighthouse is located on the shores of Lake Superior in the unorganized territory of Thunder Bay, Ontario, Canada.

Construction and History

Built in 1913, the lighthouse was designed by architect James Balfour and constructed using local stone and brick. It has been guiding mariners through the treacherous waters of the Great Lakes for over a century.

Architecture and Materials

The tower stands at an impressive height of 34 feet (10 meters) with a focal height of 130 feet (40 meters). The original Fresnel lens, installed in 1913, has been replaced several times over the years. Today, the light is automated, emitting a white light every 15 seconds (Fl(3)W.15s).

Light and Navigation

The lighthouse's characteristic pattern helps vessels distinguish it from other beacons on Lake Superior.

Accessibility and Visiting

Visitors can access the surrounding area, but the tower itself is not open to the public due to safety concerns. The site can be reached by driving along Highway 11-17 from Thunder Bay, then turning onto Porphyry Island Road.

Notable Views and Landscape

From its vantage point on the shores of Lake Superior, the lighthouse offers breathtaking views of the surrounding landscape. On a clear day, visitors can see for miles across the lake, taking in the majesty of the natural environment.

Anecdotes and Folklore

One such story tells of a former keeper who would often take his boat out onto the lake at night to spot shipwrecks, which were common in those waters. The lighthouse has also been featured in various publications, including an article by Lighthouse Friends.

Technical and Operational Details

The lighthouse was automated in 1988, eliminating the need for human operators to maintain its light.
