Þrúðheimr
In Norse mythology, Þrúðheimr (anglicized Thrúdheim or Thrudheim), which means "World of strength" in Old Norse, is the home of Thor according to the Eddic poem Grímnismál (4). But in Snorri Sturluson's Edda (Gylfaginning, 21, 47; Skáldskaparmál, 17) and Ynglinga saga (5), the name of Thor's residence is Þrúðvangr or Þrúðvangar.
