In Norse mythology, Valhalla (from Old Norse Valhöll "hall of the slain") is a majestic, enormous hall located in Asgard, ruled over by the god Odin. Chosen by Odin, half of those who die in combat travel to Valhalla upon death, led by valkyries, while the other half go to the goddess Freyja's field Fólkvangr. In Valhalla, the dead join the masses of those who have died in combat known as Einherjar and various legendary Germanic heroes and kings, as they prepare to aid Odin during the events of Ragnarök. Before the hall stands the golden tree Glasir, and the hall's ceiling is thatched with golden shields.

The concept of Valhalla continues to have influence in modern popular culture. Examples include the Walhalla temple built by Leo von Klenze for Ludwig I of Bavaria between 1830–1847 near Regensburg, Germany, and the Tresco Abbey Gardens Valhalla museum built by August Smith around 1830 to house ship figureheads from shipwrecks that occurred at the Isles of Scilly, England, where the museum is located.
