Architect extraordinaire Renzo Piano has overseen a renovation and expansion of Harvard's art museums, allowing the university's massive 250,000-piece collection to come together under one very stylish roof. Harvard's art spans the globe, with separate collections devoted to Asian and Islamic cultures (formerly the Arthur M Sackler Museum), Northern European and Germanic cultures (formerly the Busch-Reisinger Museum) and other Western art, especially European modernism (formerly the Fogg).
