Fodor's Expert Review Prince William Streetscape National Historic Site of Canada

Off King Street one block back from the waterfront, this street is full of historic buildings, particularly around Princess and Duke streets, preserving some of the city's finest late 19th-century architecture. The Old Post Office, at No. 115, is a particularly fine example. This is no frozen-in-time monument, though—these buildings now hold shops, galleries, and restaurants so good and plentiful that the site has become a dining destination. The triple-bulb lamp known as the Three Sisters, at the far end of Prince William Street, was erected in 1848 to guide ships into the harbor. Next to it is a replica of the Celtic cross on nearby Partridge Island, where many immigrants landed and were quarantined.
