With local donations and money from the Canada Works Program, a roughly half-scale replica of Seal Island Lighthouse was constructed as a base for the historic lantern room and second-order Fresnel lens removed from Seal Island in 1978. The replica, which bears the same pattern of red stripes as Seal Island Lighthouse, is thirty-five feet tall, while the original stands sixty-seven feet tall. The Fresnel lens was manufactured in Paris by Barbier, Benard, and Turenne.
The lighthouse museum was first opened to the public on July 1, 1985. Inside the lighthouse, the fourth-order Fresnel lens from Bon Portage Lighthouse is on display along with other lighthouse artifacts and artwork.
