A harbour around which Halifax Regional Municipality sprung up/was built. On one side of the harbour used to be Dartmouth, a city comprised of several smaller towns accidentally merged together, and on the other, Halifax; the two together are connected by two huge suspension bridges, and were referred to affectionately as The Twin Cities. However, Halifax Regional Municipality sprang up as a merging of Halifax, Dartmouth, and three other near communities about 5 years ago, and people have been quite successful in pretending this never happened ever since.

Within this harbour an explosion, The Halifax Explosion, took place; a munitions ship collided with another ship causing a catastrophic explosion that destroyed much of both Halifax and Dartmouth.
