Great Lakes Seaway Trail Discovery Center

The Great Lakes Seaway Trail Discovery Center is closed for the season.


Located along the Eastern Lake Ontario shores of Sackets Harbor in the historic Union Hotel, c. 1817, interactive exhibits cover a variety of topics including Maritime Heritage, Military History, Lighthouses, Natural History, Agriculture, and much more!

Murals in the second floor natural history room illustrate the major birds, mammals and fish found along the Seaway Trail in woodlands, wetlands, sand dunes and beaches, and field habitats. Can you find a cottontail rabbit, a white-tailed deer, or an Atlantic salmon? Stroll a replica of a dune walkover.

Fourteen panels in the architecture room offer a look at the works of Frank Lloyd Wright and cobblestone masons, at the treasured buildings of such communities as Sackets Harbor, Pultneyville, Oswego and Fredonia, at the seven international bridges spanning the waters between Niagara Falls, the 1000 Islands, Ogdensburg and Massena to Canada, and at such cityscapes as Delaware Avenue in Buffalo and East Avenue in Rochester.

The Maritime History theme Lighthouse and 1812 rooms overlook Lake Ontario. Aye, Captain! Come stand behind a ship’s wheel to have your photo taken. That’s Buffalo Main Light in a wall mural. In the 1812 room, an old-fashioned apothecary cabinet might have dispensed remedies to soldiers and sailors. Aerial photos show three sites important during the conflict: Fort Ontario in Oswego, Old Fort Niagara in Youngstown, and Madison Barracks’ water tower. A sepia-tone map sites the 1812 historic markers “museum without walls” found at 42 stops Trail-wide.
