Cape Breton Island
Island forming part of Nova Scotia, Canada, with a history of coal mining and French fortifications.
Cape Breton Island is the largest offshore island forming the bulk of the eastern part of the province of Nova Scotia. It is notable for its mining industry, particularly the coal that was discovered in rocks and cliffs by explorers and settlers in the 17th and 18th centuries. Coal was used to heat houses and factories, used by blacksmiths to mold iron, and for the steam engines of trains. Coal was extracted principally in the Sydney–Glace Bay area until the mines were closed in 2001. Many mines have shut down as coal becomes a less popular fuel, though Nova Scotia still gets most of its electricity from coal, most of which is now imported. Some of Cape Breton's mines have been turned into tourist attractions and museums, with retired miners taking people on tours of old mines.

Lore & Background
Cape Breton Island was once attached to Scandinavia and Scotland as part of the Avalon terrane, before continental drift joined it to present-day North America. The French maintained control of Cape Breton Island (which they called Île Royale) after the Treaty of Utrecht in 1713, while Britain gained control of present-day peninsular Nova Scotia. The largest defensive installation in Nova Scotia was a French military fortified port at Louisbourg Harbour on Cape Breton Island. The fortified military port of Halifax on Halifax Harbour was founded to counter Louisbourg's presence. Cape Breton Island was created as a separate colony in 1784 to accommodate United Empire Loyalist refugees, but in 1820 it was permanently folded back into Nova Scotia, resulting in the present-day provincial territory. The Bras d'Or Lake, a 1,100 square kilometres (420 sq mi) estuary, defines the central portion of Cape Breton Island.
Reader's Guide
Visitors to Cape Breton Island can explore the legacy of its coal mining industry, which was concentrated in the Sydney–Glace Bay area. Many mines have been turned into tourist attractions and museums, where retired miners lead tours of old mines. The island also features the historic French fortified port at Louisbourg Harbour, the largest defensive installation established along Nova Scotia's coastal settlements. The Cabot Strait lies north and east of Cape Breton Island, and the island's southern and eastern parts constitute a pelagic coast fronting the open Atlantic Ocean. The Bras d'Or Lake, a large estuary at the centre of the island, offers a unique inland waterway. The island's rugged terrain and coastal landforms, shaped by glaciation and rising sea levels, provide a varied landscape from rocky shores to sandy beaches.
