Mason Hall was the first University of Michigan building devoted to instruction was known as the University Main Building upon completion in 1841 in time for fall classes.
In 1849, a similar building called South College was constructed south of Mason Hall. University Hall (built 1871-1873) connected the two buildings, which then were referred to as South Wing and North Wing.
The Law Building was built in 1863, renamed Haven Hall in 1933, and destroyed by fire in 1950. In 1950, after the fire destroyed Haven Hall, the entire University Hall complex was removed to make room for the expansion of Angell Hall.
