Main Hall was named to honor President John Hanson Thomas Main, who conceived of and carried forward the idea of Grinnell as a residential college. Through the investment of about $1 million, the College built the Women's Quadrangle in 1915, and the men's halls in 1916-17. Main Hall serves as the central building of the South Campus residence Halls, and at the time of its opening, it included a beautiful drawing room, an inspiring Gothic dining room, and the Little Theatre.
Gardner Lounge, in the basement of Main Hall, has hosted performances by Smashing Pumpkins, Nirvana, and more. Today, Main Hall boasts a student run café in the basement (Bob’s Underground), Gardner Lounge, and an expansive lounge on the first floor.
