Seven kilometers east of town, this museum narrates the Empress of Ireland tragedy, the worst disaster in maritime history after the Titanic . In the 14 minutes it took for the ship to disappear into the St Lawrence after colliding with a Norwegian collier, 1012 people lost their lives. The disaster was all but forgotten with the outbreak of WWI two months later.
You can also join a free tour of Pointe au Père Lighthouse next door, the highest in eastern Canada.
The former keeper's cottage has displays on navigating the river and diving to the Empress, 45m down.
The wreck itself is considered one of the world's premier scuba diving sites. However, this is a dangerous dive; several inexperienced divers have died. Currents, visibility and water temperature are serious challenges.
