The Custom House Tower

The Custom House Tower, located in the heart of Boston’s Financial District, is a historic skyscraper that has been a prominent feature of the city’s skyline since its completion. Originally built as a customs house for the port of Boston, the building has evolved over time and now serves as a mixed-use property featuring a hotel.


The original Custom House was constructed in the 1840s, while the tower was added later, between 1913 and 1915. At the time of its completion, the Custom House Tower was the tallest building in Boston. It was designed in the neoclassical style with a Greek temple-like base. The tower’s design was intended to reflect the importance and stability of the United States Federal Government.


  • Height: The Custom House Tower stands at 496 feet tall, including its distinctive clock tower.
  • Architecture: The building features a neoclassical style with a pyramidal roof and a clock on each of its four sides.
  • Landmark: It was designated as a National Historic Landmark in 1973.
  • Usage: The tower is now part of the Marriott’s portfolio of properties and operates as the Marriott Custom House Hotel.


The Custom House Tower is situated at 3 McKinley Square, Boston, MA 02109, near the waterfront and Faneuil Hall Marketplace.
