The Doomsday Clock is a symbolic clock face intended to convey how close humanity is to catastrophic destruction - the figurative midnight. In order to gauge the “time” its hosts monitor the means of potential annihilation. First and foremost are nuclear weapons, but they also observe climate-changing technologies and new developments in the life sciences that could inflict irrevocable harm.
The Fortress of Louisbourg is a national historic site and a partial reconstruction of an 18th century French fortress at Louisbourg, Nova Scotia.
The original fortress, constructed between 1720 and 1740, was one of the most extensive European fortifications constructed in North America. Captured by British colonists in 1745, it was a major bargaining chip in the negotiations leading to the 1748 treaty ending the War of the Austrian Succession, and was returned to French control. It was captured again in 1758, by British forces during the Seven Years' War, after which it was systematically destroyed by British engineers.
