Bishop Hill was the site of a utopian religious community founded in 1846 by Swedish pietist Eric Janson (1808–1850) and his followers. A number of historically significant buildings have survived and are scattered throughout the village, four of which are owned by the state and managed as part of the Bishop Hill State Historic Site. The 1848 Colony Church is a two-story frame building. The three-story stuccoed-brick 1850s Colony Hotel served commercial travelers and provided a link to the outside world. The 1850 "Boys' Dormitory" is a small two-story frame structure believed to have provided housing for boys making the transition to working adulthood. An 1850s Colony barn was relocated behind the Hotel to the site of the original Hotel stable.

The 1765 Palladian-style Morris-Jumel Mansion is the oldest residence in Manhattan. It served as the headquarters of George Washington between September and October 1776.

After the Revolutionary War, the home became an inn; and the interior was decorated in the French Imperial style in the early 19th-century. John Adams, John Quincy Adams, Thomas Jefferson, Henry Knox, and Alexander Hamilton all dined at the site in 1790.
