Neue Galerie New York

Dating back to 1663, this fort was used during both the American Revolution and the War of 1812. It remained active until 1995. It is now semi-active, with its main use being local headquarters for the United States Coast Guard. Tours are available.

A vintage carousel built in 1908 and situated on this spot since the 1950s, it's the fourth carousel to inhabit this location and is beautifully painted.

This pretty building was built as Brooklyn's city hall in 1851 and is still a very significant official building in very active use.

A museum dedicated to folk & self-taught artists.

Built in 1765, this is the oldest house on Manhattan Island. It served as George Washington's headquarters in 1776. Now a museum set on a 1.5-acre park, it features a decorative-arts collection representing the colonial and Revolutionary War periods. Washington's office is among the 12 restored rooms.

A small park at the foot of Broadway which is the oldest public park in the city and is the site of the Charging Bull sculpture created after the 1987 stock market crash. Bowling Green is also the origin point for the Broadway ticker-tape parades; if you walk up Broadway, you can view plaques in the sidewalk honoring the people or events celebrated in these parades.

So named in 1981 in memory of John Lennon, the former Beatle, who was murdered close by outside his home in the Dakota building. Lennon's widow Yoko Ono, who still lives in the Dakota, subsequently donated $1 million to upgrade the area with hundreds of tree and flower species, including strawberries. The area serves as a Garden of Peace and includes a memorial floor mosaic (donated by the Italian city of Naples) that says simply "Imagine", referring to the title of one of Lennon's evocative songs.

A riverfront park providing pleasant views of New Jersey and sometimes breezes off the river. Summer brings al fresco movies and music to the park.

Located on four acres overlooking the Hudson River in Fort Tryon Park, the building incorporates elements from five medieval French cloisters – quadrangles enclosed by a roofed or vaulted passageway, or arcade – and from other monastic sites in southern France. There are various artworks on display in the museum, with the Unicorn Tapestries being the most famous.

For most of the 18th century, Africans in New York City were buried in a graveyard outside the city. The graveyard was eventually forgotten and was rediscovered in 1991. This museum and memorial site commemorate the estimated 15,000 Africans that were interred on the site of the memorial. Note that the museum is located inside of a Federal building so airport-style security should be expected.

One of the Seven Sisters colleges, and is affiliated with Columbia University.

The former residence of William Dyckman, who owned several hundred acres of farmland covering much of what is now Inwood and Washington heights. Nestled incongruously at the otherwise unremarkable corner of 204th and Broadway, the farmhouse has been converted into a small museum of life in early Manhattan and hosts various programs for the neighborhood. The "Hessian Huts" in the back yard are a leftover from the British occupation of Manhattan during the Revolutionary War!

A museum and library devoted to Spanish, Portuguese, and Latin American art and culture.

Supported by the Museum of Modern Art, this innovative (and cheap) contemporary art museum is in a former public school building. The conversion left most of the original features of the school - the large ex-classrooms are perfect for installations - and the bathrooms are a blast from the past. P.S.1 is a few blocks south on Jackson Avenue from the Citibank tower; the entrance is a concrete slab (how fitting) which occludes view of the school itself. P.S.1 also has a nice cafe and outdoor seats.

Affiliated with Columbia, Teacher's College is an architectural gem with its block length Beaux Arts and neo-Gothic façades.

The historic building with the distinctive, iconic twin towers and a star-studded housing cooperative board. Built in 1930 in a vaguely Art Deco style to the design of Emery Roth, the San Remo actually has two separate addresses, lobbies and sets of shafts, each for a half of the building topped with a tower.

Established in 1867 and laid out by Olmsted and Vaux, the designers of Manhattan's Central Park.

Dates back to 1680, and held an abortive peace conference during the Revolutionary War.
