In 1825, the Main College consisted of two three-story x buildings known as the "North and South Colleges". A third three-story building (with a length of ), known as the "Middle College" was erected between the two in 1829. Each of the buildings was constructed about 7–8 feet apart to prevent fire from destroying the entire facility, as had occurred previously in 1824. In 1846, the buildings were connected, however they were not accessible to one another within. The building has undergone substantial renovations during several times.
