Conception Bay covers an area of 1295 square kilometres and contains several islands, the three largest being Bell Island, Little Bell Island and Kellys Island. The Bay is fed by rivers from its east and west, which flow on into the Atlantic Ocean.
Conception Bay was the site of Britaniola Colony, established in 1610. It was the site of Sea-Forest Plantation founded in 1610 and Bristol's Hope Plantation founded in 1619. During the 1610s, the Bay was the hideout of the infamous Newfoundland based buccaneer, Peter Easton; artifacts from the 17th-century confirmed the presence of Easton and his pirate crew in the Bay, such as Spanish coins, found to be minted in Peru. There was trade between Newfoundland and Bilbao during the 17th century.
Conception Bay South was formed in 1973 through the amalgamation of nine communities (Topsail, Chamberlains, Manuels, Long Pond, Foxtrap, Kelligrews, Upper Gullies, Lawrence Pond and Seal Cove) all of which follow the coastline of Conception Bay.
The early residents, mainly English but some Irish, were attracted by good growing land, abundant supplies of firewood and the more temperate climate as compared to other parts of the Avalon Peninsula. Good communication with St. John's was established by road in the 1830s and strengthened in the 1880s with the arrival of the railway. Residents of Conception Bay South grew crops and raised cattle for the St. John's market and St. John's residents established summer homes in Conception Bay South.
