UCI opened in 1965 with only 8 buildings on its main campus. Over the next 50 years, continuing construction has increased the total to more than 170 buildings, with no end in sight. Once home to grazing cattle, the site has been transformed from vacant hills into an architectural gallery. William Pereira, UCI's first architect, created a modern, master-planned campus design. A post-modern response came in the 1980s and 1990s, as new buildings were designed by celebrated architects.
