The 158 buildings on main campus comprise more than 4.6 million square feet (325,000 m2) of academic, research, and residential space.[1] Many of the Main Campus buildings feature the Spanish–Mission style architecture; inspiration drawn from Thomas Jarvis' time as an ambassador to Brazil.[19][20] He wanted to bring the unique architecture to eastern North Carolina. On the main campus, there are five districts: Campus Core, Downtown District, Warehouse District, Athletic fields and the South Academic District.
