Later Changes
The central spire was removed in 1916 due to structural concerns, completely changing the character of the structure, and resulting in a somewhat awkward central section (now hidden by two large spruce trees). After the campus expanded the building was renamed the Language Building.
The auditorium was reduced in size during a 1936 renovation and then completely removed in 1949. This remodeling drastically changed the building's interior and did not match the original style. The auditorium was replaced by a large central staircase and two stories of office space still in use today. The 1949 remodeling also officially changed the buildings name to Old Main. The office of the president was remodeled at this time and remains much unchanged today.
Originally the entrances to Old Main were elevated above ground level so that visitors would ascend to the first floor before entering the building; they were modified in 1949 so that visitors now enter down to the basement level.
