Navigating Alaskan Maritime History

Alaska’s Lighthouses: Guides Through Wild Waters

Explore the lights that helped mariners navigate Alaska’s rugged coast, from Mary Island to Point Retreat and beyond.

Keeping Watch Along Alaska’s Coast

Along Alaska’s island passages and exposed shores, lighthouses and other light structures have helped vessels identify hazards, locate channels, and approach communities more safely. Mary Island Light marks a key area near the southern entrance to the Inside Passage, while Point Retreat guides traffic in Southeast Alaska’s Lynn Canal. Each light has a story shaped by the mariners, keepers, and coastal communities that depended on it. Alaska Lighthouses brings together public information and historic context to trace those stories and show why these landmarks still matter.
