Sessrúmnir
In Norse mythology, Sessrúmnir (Old Norse "seat-room" or "seat-roomer") is both the goddess Freyja's hall located in Fólkvangr, a field where Freyja receives half of those who die in battle, and also the name of a ship. Both the hall and the ship are attested in the Prose Edda, written in the 13th century by Snorri Sturluson. Scholarly theories have been proposed regarding a potential relation between the hall and the ship.
Attestations
Sessrúmnir is specifically referred to as a hall in chapter 24 of the Prose Edda book Gylfaginning. After describing Fólkvangr, High tells Gangleri (described as king Gylfi in disguise) that Freyja has the hall Sessrúmnir, and that "it is large and beautiful".
Sessrúmnir is secondly referred to in chapter 20 of the Prose Edda book Skáldskaparmál. In the chapter, means of referring to Freyja are given, including a reference to Sessrúmnir: "possessor of the fallen slain and of Sessrúmnir [...]". Sessrúmnir is referenced a third and final time within a list of ship names in chapter 75.
