Fort Flagler Historical State Park

Fort Flagler Historical State Park is a 1,451-acre park on Marrowstone Island containing ten coastal defense batteries and military structures. The fortifications and gun positions spread across hilly terrain with water views from many locations.

This fort was established in 1897 and formed a defensive triangle with Fort Worden and Fort Casey to control the entrance to Puget Sound. The three positions worked together to guard Admiralty Inlet against naval attack.

The museum inside displays military gear and exhibits showing how this fort protected Pacific Northwest waterways. Visitors can explore the buildings and fortifications to understand how soldiers lived and worked on the island.

The park is easy to explore on trails leading to the batteries and historic buildings, with information signs at key spots. You can stay overnight in the former military buildings or simply walk through the grounds to enjoy the coastal views.

Soldiers at this fort could hear orchestral music drifting across the water from nearby Fort Worden on steamships passing the coast. This musical connection between the installations became part of everyday life at this remote post.
