This grand building was built to house the private library of J.P. Morgan. Designed by McKim, Mead & White, it contains a highly valuable collection of prints, drawings, illustrated books and early manuscripts. It now has a large extension designed by noted architect Renzo Piano along with a new auditorium, café and reading room.

This small museum features rotating exhibits that range from modern Scandinavian furniture to works by noted artist Louis Matthiasdottir. They also run a regular film series covering both historical and contemporary Scandinavian cinema. If you should need a break from all this culture, there's a terrific little café run by the folks who own Aquavit.
