Columbia Island – a small island (approx. 150 feet (46 m) square) situated between Davids Island and Pea Island. Up until 1940 it was known as Little Pea Island. CBS purchased it and built a concrete foundation to support a transmitter building topped by a 410-foot (120 m) tall antenna tower for WCBS-AM.

The transmitter remained in operation until the 1960s, when the station was moved to nearby High Island. Execution Rocks Lighthouse – centered in the middle of Long Island Sound, just south of Davids Island. The structure was built in 1849 and includes a 55-foot (17 m) tall tower and the 'keeper's house'.

It is rumored that the lighthouse's site got its name before the American Revolutionary War when British colonial authorities executed people by chaining them to the rocks at low tide and allowing the rising water to drown them. In reality, the name was chosen to reflect the historically dangerous shipping area created by the rocks exposure during low tides. Huckleberry Island – a 10-acre (40,000 m2) island owned by the Huckleberry Indians, Inc., a club within the New York Athletic Club.

The island is an important nesting site for waterbirds such as egrets and night herons. Leland Castle – a 19th-century Gothic Revival castle built as the summer residence of Simeon Leland, a wealthy New York City hotel entrepreneur. It has since been acquired by the College of New Rochelle and is used as an art gallery available to the public. St.

John's Wilmot Church – a historic Episcopal parish located in the northern end of the City at the intersection of North Avenue and Wilmot Road, formerly referred to as "Cooper's Corner". Thomas Paine Historical Site – a historical nexus within the city, the site comprises: the country home of the American pamphleteer and Revolutionary War hero Thomas Paine, his burial site, monument, and a museum.

Paine's Cottage was built in 1793 and is a National Historic Landmark. The Thomas Paine Memorial Building, built in 1925, houses the library and museum collection of the Thomas Paine National Historical Association. Also on the site is the Brewster Schoolhouse, one of the oldest structural relics in Westchester County. Trinity-St.

Paul's Episcopal Church – added to the National Register of Historic Places in 2006. It is located at the northwest corner of Huguenot Street (also known as the Boston Post Road) and Division Street. This church represents the body of the majority group of New Rochelle's founding Huguenot French Calvinistic congregation that conformed to the liturgy of the established Church of England in June 1709.

King George III gave Trinity its first charter in 1762. After the Revolutionary War, Trinity became a parish of the Protestant Episcopal Church of America.
