866 United Nations Plaza is the only office building within the submarket that lies east of First Avenue, other than the Secretariat Building itself. Located directly north of the United Nations on 48th Street, the building gives the impression that it is an extension of the United Nations campus. In addition to its own on-site parking garage, which provides added security and convenience, the United Nations garage is across the street from the entrance to 866 United Nations Plaza. 866 United Nations Plaza is the premier office building in this submarket and serves as a cornerstone to the international community. Since 1965, the building has been home to prestigious missions, consulates and non-governmental organizations (NGOs), as well as highly-respected legal firms, consultants and countless businesses that serve the United Nations community.
