It houses the university's chief administrative headquarters and classroom and office space for several academic departments.","why_significant":"The nomination argues College Hall is pivotal in linking pre- and post-Civil War design, showing the influence of Samuel Sloan's linear pavilion plans and an early expression of late nineteenth-century complexity and polychromy. It is regarded as the major surviving work of architect Thomas W. Richards, whose teaching at Penn influenced several later architects. It also holds a continuing role in defining the campus's sense of place and historical continuity.","narrative":"Built in 1871-1872 on the University of Pennsylvania campus in West Philadelphia, College Hall is a four to five story masonry building with a central pavilion flanked by smaller pavilions attached perpendicularly to a linear core. Its administrative offices and a two-story chapel occupied the center, while collegiate departments were housed west of it and scientific departments to the east. Richards designed the building with dark grey schist, green serpentine walls, brownstone and Ohio stone trim, and a slate mansard roof with wooden dormers, creating a polychromatic effect. The building is regarded as an important link between pre- and post-Civil War design and as the major surviving work of Thomas W. Richards, whose teaching at Penn produced several nationally known architects. Contemporaries praised its planning, and it continues to anchor the campus's historical identity. Serpentine deterioration led to the removal of its towers and repeated repairs.","period_of_significance":"1871-1872","architect_builder":"Thomas W.
