Harbour Grace is a town in Conception Bay on the Avalon Peninsula in the province of Newfoundland and Labrador, Canada.

[3] Harbour Grace was an important port and fishing centre from the earliest days of European exploration of North America.

[4] In 1610, pirate Peter Easton made Harbour Grace his headquarters, and established a fort overlooking the bay.

Although it was attacked by the French the following year, the early settlement survived throughout the 17th century, with a permanent, year-round population numbering a few dozen, swelling to several hundred during the fishing season.

[7] In July 1941, the Royal Canadian Navy established a High Frequency Direction Finding wireless station on the airfield.

Consisting of an Operations Building and a Direction Finding shack, the station had an uninterrupted sweep of the northern Atlantic sector and was able to provide bearings on U-boat transmissions and to intercept enemy radio traffic.

In addition, because of its rich history and many historical buildings, including the 1870 customs house, now the Conception Bay Museum Archived 2018-10-03 at the Wayback Machine, a small tourist industry is emerging.
