A famous Ivy League college that has existed since British colonial times, when it was called King's College.

This beautiful park extends along the Hudson River north of Riverside Park and features wonderful views of the George Washington Bridge and New Jersey and a community feel.

Large garden and arboretum featuring a variety of plants, and also a Victorian-style wedding garden.

The original subway station, and quite a marvel to witness--the chandeliers and ornate tiling are a sharp contrast to the nearby Brooklyn Bridge-City Hall station. There's one catch, though: it's been closed since 1945. However, you can see it by staying on the downtown 6 train after its last stop Brooklyn Bridge-City Hall; it will turn around in the old station. This is the one place in the system where this is allowed, and the announcements reflect that. The Transit Museum (in Downtown Brooklyn) offers occasional tours as well, which allow you to actually walk around the station, but you must be a museum member and a US citizen, making this an impractical choice for most visitors.

A self supporting arm of the MTA, it is housed in the Subway's former Court Street Station, on a spur line from the current A and C lines. Closed to passengers in 1946, it was reopened in 1976 as the New York Transit Exhibit and was popular enough to be made permanent. The museum is made up of two underground levels: the Mezzanine, which hosts exhibits on the construction of the subway, surface transportation in New York, fare collection and rotating exhibits on various transit-related subjects; and the station platform, which houses about 20 retired subway cars dating as far back as 1903 and a working signal tower. The museum sponsors events throughout the year, including simple art projects, walking tours on the subway, and rides on the museums' fleet of retired trains. There is also an annex of the museum in Grand Central Station in Midtown Manhattan.

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

Built in 1802 (and physically shifted from its original location), this was the home of Alexander Hamilton, one of the founding fathers and the first Secretary of Treasury.

A 2011 addition to the Lower Manhattan skyline, this 76-story residential skyscraper by the noted Frank Gehry has a distinctive rippled, "wavy" facade that is quite eye-catching. It is best viewed from City Hall Park and the Brooklyn Bridge.

This pretty 17-story Beaux Arts building was completed in 1904 and designed to be New York City's first air conditioned hotel. It was a residential hotel, and housed a number of very famous people, including the Hall of Fame baseball player, Babe Ruth; the Italian tenor, Enrico Caruso; the modernist composer, Igor Stravinsky; the Italian conductor of the NBC Symphony, Arturo Toscanini; and writers Theodore Dreiser and Isaac Bashevis Singer. The building is now a condominium.

One of New York's most beautiful parks, an expanse of rolling hills high above the Hudson, contains some of the highest natural elevations on the island and is a great place to picnic or stroll in good weather and look at the great views of the New Jersey Palisades across the river.

The lesser-known historic district on the other side of the Park. It was developed at the turn of the 20th century by Dean Alvord as one of the first suburbs.

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.

The One World Trade Center skyscraper rises 1,776 feet above the street and is the tallest building in the United States (and for that matter, the Western Hemisphere). Despite its colossal size, its simple design allows it to blend remarkably well into the Lower Manhattan skyline. An observation deck on the top floors offers 360-degree views of the city.
