1 Hanover Square

1 Hanover Square is an exchange building in Manhattan's Financial District designed with Renaissance-style architecture. The three-story brownstone structure displays eight vertical bays and Corinthian columns facing the square, while a 2022 renovation preserved its historical character while creating contemporary office spaces.

The building was constructed in 1854 and housed America's first cotton futures exchange from 1872 to 1885. This function established it as an important location in the nation's financial history.

The India House Club has occupied the building since 1914, filling its interior with maritime objects that reflect New York's role in world trade. Visitors can see these seafaring collections throughout the rooms, telling the story of the city's global commerce connections.

The building sits on Hanover Square and is easily accessible by public transportation from various parts of Manhattan. The exterior facade remains fully viewable from the street, making it simple to appreciate the architectural details from outside.

The building incorporates parts of commercial structures dating back to 1836, making it a layered blend of different construction periods. The original 1854 brownstone entrance stands alongside these older elements, revealing how different eras of Manhattan's growth became intertwined in a single structure.
