Warren Hall

E. Guy Warren Hall, commonly known as Warren Hall, was a 13-story building at California State University, East Bay. It was the signature building of the campus in Hayward, California, overlooking the East Bay region of the San Francisco Bay Area. The building was visible from cities throughout the Bay Area, and served as a landmark for Hayward and the East Bay. It was the tallest building in Hayward at the time, followed by the abandoned City Center Building in downtown Hayward.
