Valhalla has two primary meanings depending on context:
- In Norse mythology, Valhalla is a majestic hall located in Asgard, ruled by the god Odin. It is known as the Hall of the Slain, where the bravest warriors who die in battle are taken by Valkyries to live gloriously until Ragnarök (the end of the world), when they will fight alongside Odin.
- Valhalla is also the name of a hamlet and census-designated place in Mount Pleasant, Westchester County, New York, United States. This place was named after the mythological Valhalla and is known for the Westchester Medical Center and Kensico Cemetery.
So, depending on the intended meaning, Valhalla is either a mythical hall in the Norse realm of Asgard or a real-world location in New York, USA. The mythological Valhalla is believed to be located in Asgard, the celestial fortress of the gods in Norse cosmology.
