Signal Hill National Historic Site, at the mouth of St. John's Harbour, commemorates the cliff top where signal flags once alerted merchants, customs officials and harbor pilots to approaching ships, be they friend or foe.

Depending on the time of year, from the top of Cape Spear, you might see icebergs (they float over from Greenland), whales or seabirds.

The Rooms is a cultural museum, art gallery and provincial archives rolled into one.

An accident of storing port wine in St. John's in the late 1600s seemed to give the wine a better flavor. Hence, the practice of leaving port to mature in Newman Wine Vaults, not to mention the ensuing ghostly tales. The brick and stone vaults that remain are among the city's oldest structures, and tours capitalize on the haunted factor to build intrigue. Sampling port helps, too. (435 Water Street; Open 1 p.m. to 5 p.m. Wednesday to Sunday, July to August)
