Once called Crow’s Nest Cove, the area became known as The Battery when military posts were installed here to protect the harbour. This conversion began in the 17th century when defense was needed against the French. But despite numerous battles and wars over the years, The Battery always remained a fishing community.
The story of The Battery echoes the dramatic social, cultural and economic changes that have been occurring in outports throughout Newfoundland and Labrador. Having said that, you can always find local people who are interested in preserving the vernacular architecture and cultural heritage around them.
