About Trowbridge Island Lighthouse
The Trowbridge Island Lighthouse was built in 1924 as an octagonal concrete structure standing 7 meters tall. It is painted white with red trim, and its lantern and gallery are also red. The lighthouse emits a single white flash every 5 seconds from a focal height of 35 meters, visible for 16.2 nautical miles. This facility is situated on a small island east of Thunder Cape, serving as a key marker for vessels approaching Thunder Bay. Since 2018, Canadian Lighthouses of Lake Superior has managed the site, following efforts by the Friends of Trowbridge Island Lighthouse to ensure its preservation.
Why it matters: The lighthouse is essential for safe navigation into Thunder Bay, guiding vessels through the waters near Thunder Cape. Its preservation by Canadian Lighthouses of Lake Superior highlights its cultural value as a heritage site.
