Powell Library is the main college undergraduate library on the campus of the University of California, Los Angeles (UCLA). Powell Library is also known as the College Library. It was constructed from 1926 to 1929 and was one of the original four buildings that comprised the UCLA campus in the early period of the university's life. Its Romanesque Revival architecture design, its historic value and its popularity with students make it one of the defining images of UCLA. There are also Renaissance Printers' Marks on the ceiling.
