Asgard (home of the gods) In Norse mythology, home of the Aesir gods. Asgard was surrounded by an enormous wall and consisted of many palaces, such as Valaskjalf, a hall roofed with silver in which the god Odin lived. Valaskjalf contained a room, Valhalla, the hall of the slain, where those who had died in battle were feasted by the gods.
Asgard was encircled by a wall built by the giant Hrim-thurs to protect it from the frost giants. Heimdall was the watchman at the gate to Asgard, which could be reached only by crossing Bifrost Bridge. It was believed that Asgard would be destroyed at the end of the world, Ragnarok, but finally restored to even greater glory
