Northwest Seaport

Northwest Seaport Maritime Heritage Center is a nonprofit organization in Seattle, Washington dedicated to the preservation and interpretation of Puget Sound and Northwest Coast maritime heritage, expressed through educational programs and experiences available to the public aboard its ships. The organization owns three large historic vessels docked at the Historic Ships' Wharf in Seattle's Lake Union Park; the tugboat Arthur Foss (1889), Lightship 83 Swiftsure (1904), and the halibut fishing schooner Tordenskjold (1911). These vessels are used as platforms for a variety of public programs, ranging from tours and festivals to restoration workshops and vocational training.

Northwest Seaport is adjacent to the Center for Wooden Boats and the Museum of History and Industry on the south shore of Lake Union in downtown Seattle. These organizations have partnered in many public programs and events at Lake Union Park but are not affiliated with each other. Northwest Seaport also is not affiliated in any way with the Northwest Seaport Alliance, the joint port authority for the cities of Seattle and Tacoma, newly formed in 2015.
