A 3-D show that re-creates the grand, but more often grim, realities of the evolution of the city -- the difficult weather conditions endured by the European explorers in the 17th century, the disease and fire that plagued immigrant workers in Old Port in the 18th century, the wars between French and British troops in the 19th century, and modern construction disasters in the 20th century. Guns and cannons point at audiences, a simulated bridge comes crashing down, and faux flames and screams fill the hall. All in all, it's quite vivid. Take a padded bench seat at least halfway back to get the full experience, and prepare to leave expecting an anvil or piano to land on your head. It lasts about 30 minutes.
