Sixteen forty-two as a Catholic mission. Eighteen thirty as a commercial port. Nineteen sixty-four as a heritage district. Forty hectares hold all three foundings simultaneously, and the seams are legible at every corner.

Place d'Armes: The Gate

Four buildings, four centuries. The 1687 seminary, the 1829 basilica, the 1847 bank, and the 1895 monument that names what the corridor was built on.

James O'Donnell's 1829 neo-Gothic shell, holding Victor Bourgeau's 1879 interior. One basilica, two architects two generations apart.

The triangular point where Maisonneuve landed on 17 May 1642. A 1992 museum opened on the 350th anniversary day, over the archaeological remains of the fort.

The oldest street in Montréal, laid out by François Dollier de Casson in 1672. Three centuries of Catholic women's institutional work, one street block.

The 1830 Harbour Commission, the 1825 Lachine Canal that built it, and the 1992 redevelopment that recovered it from industrial obsolescence.

Montréal's oldest public monument, on a square that was a French regime garden, a market, and finally a 1535-commemorative space, on the same paving.

An 1878 Second Empire building, gutted by fire in 1922, rebuilt as a steel frame inside the original stone shell in 1926, and the site of Charles de Gaulle's 1967 speech.

Gaspard-Joseph Chaussegros de Léry's 1717 fortification line, demolished 1801 to 1817, excavated 1986 to 1991, exposed in the 1992 plaza. The corridor walked, in one frame.
Weekday mid-morning, Tuesday through Thursday, between nine and noon. Place d'Armes and Rue Saint-Paul fill with cruise-ship and bus-tour visitors from late morning through late afternoon in summer; the basilica entrance queue can reach forty-five minutes at peak. The corridor is quieter on weekday mornings in shoulder season (May, early June, late September, October). Winter walks the corridor with almost no crowds, but the Champ-de-Mars stone lines at Stop 8 are often snow-covered between December and March; an off-season visit favours November or April. The Pointe-à-Callière Museum is closed Mondays for most of the year.
