Somerville Mechanics Institute Hall is an established community hall at 66 Station Street, Somerville, used for meetings, performances, celebrations and local programs. Mornington Peninsula Shire’s 2026–27 regular-hire information lists a 200-person hall capacity. The character venue offers a more traditional gathering setting than a contemporary conference centre; organisers should confirm current room divisions, furniture, kitchen, accessibility and authorised layouts directly with the council rather than using third-party seating estimates.
