Museum at Michel Delving in the Shire. The Mathom-house was so called because it was full of mathoms, items that Hobbits had no particular use for but could not bear to throw away. Many of the weapons in the Shire were displayed in the Mathom-house since Hobbits had no need for them in their peaceful land. The most precious item in the museum's collection was the mithril shirt belonging to Bilbo Baggins. Bilbo loaned the coat of mail to the Mathom-house sometime after returning from the Lonely Mountain in 2942. He reclaimed the mithril shirt in 3001 when he left the Shire.
