St. John's is the capital and largest city in Newfoundland and Labrador, Canada. St. John's was incorporated as a city in 1921, yet is considered by some to be the oldest English-founded city in North America, having been first settled in 1630 or so. It is located on the eastern tip of the Avalon Peninsula on the island of Newfoundland. With a population of 200,600 as of 2012, the St. John's Metropolitan Area is the second largest Metropolitan Area in Atlantic Canada after Halifax and the 20th largest metropolitan area in Canada. Its name has been attributed to the feast day of John the Baptist, when John Cabot was believed to have sailed into the harbour in 1497, and also to a Basque fishing town with the same name. Long primarily a fishing and naval station, it declined in recent decades, only to be revived by offshore oil drilling in recent times. It is also the location from which Marconi received the first trans-atlantic wireless signal in 1901.
