Jefferson was a strong disciple of Greek and Roman architectural styles, which he believed to be most representative of American democracy. Each academic unit, called a pavilion, was designed with a two-story temple front, while the library "Rotunda" was modeled on the Roman Pantheon. Jefferson referred to the university's grounds as the "Academical Village," and he reflected his educational ideas in its layout. The ten pavilions included classrooms and faculty residences; they formed a quadrangle and were connected by colonnades, behind which stood the students' rows of rooms. Gardens and vegetable plots were placed behind the pavilions and were surrounded by serpentine walls, affirming the importance of the agrarian lifestyle. The university had a library rather than a church at its center, emphasizing its secular nature—a controversial aspect at the time.
