New Haven is best known as the home of Yale University, and the campus shapes the city with museums, libraries, and historic architecture. The Yale University Art Gallery and the Yale Center for British Art are free to visit and draw art lovers from across the region. The New Haven Green, a large public square dating to the colonial era, anchors downtown, while Wooster Square is known for its historic homes and cherry trees in spring. East Rock Park rises above the city with views over the harbor and Long Island Sound.
