Halifax Regional Municipality in the context of "Amalgamation of the Halifax Regional Municipality"

Halifax Harbour is a large natural harbour on the Atlantic coast of Nova Scotia, Canada, located in the Halifax Regional Municipality. Halifax largely owes its existence to the harbour, being one of the largest and deepest ice-free natural harbours in the world. Before Confederation it was one of the most important commercial ports on the Atlantic seaboard. In 1917, it was the site of the world's largest man-made accidental explosion, when the SS Mont-Blanc blew up in the Halifax Explosion on December 6.

The harbour was formed by a drowned glacial valley which succumbed to sea level rise after glaciation. The Sackville River now empties into the upper end of the harbour in Bedford Basin. The harbour also includes the Northwest Arm and The Narrows, a constricted passage to Bedford Basin.

Bedford (pop. 36,354 ) is a former town and now a district of Halifax, Nova Scotia, Canada. It is situated on the north west shore of the Bedford Basin in the central area of the municipality. It borders the neighbouring communities of Hammonds Plains to the west, Sackville to the north, Dartmouth to the east, and mainland Halifax to the south. Bedford was named in honour of John Russell, 4th Duke of Bedford, Secretary of State for the colonies in 1749.

Dartmouth (/ˈdɑːrtməθ/ DART-məth) is a built-up community of the Halifax Regional Municipality, Nova Scotia, Canada. Located on the eastern shore of Halifax Harbour, Dartmouth has 72,139 residents as of 2021.

A Martello tower is a type of small defensive fort that was built across the British Empire during the 19th century, from the time of the French Revolutionary Wars onwards. Most were for coastal defense.

A Martello tower stands up to 40 feet (12 m) high, with two floors and a typical garrison of one officer and 15–25 men. The round structure and thick solid masonry walls made it resistant to cannon fire, while its height made it an ideal platform for a single heavy artillery piece, mounted on the flat roof and able to traverse over a complete 360 degrees. A few towers had moats or other batteries and works attached for extra defence.
