With New York City growing and not enough space in the City Hall building, this 40-story structure was built to meet the space demands of the city government. Completed in 1915, it is a massive and very grand building with the gilded statue of a woman standing atop the building's spire.

A place filled with video screens, LED signs, and flashing lights; a world wonder or a tourist nightmare depending on your perspective, the "new" Times Square is a family-friendly theme park of themed restaurants, theaters and hotels, as well as a developing business district. The lights and signs can be viewed anytime, but the most enchanting experience comes when one visits Times Square at night, as all the signs and screens are ablaze with color. Times Square is also well known for its famous New Year's Eve ball drop. Those looking for the seedy Times Square of years past will find it around the Port Authority Bus Terminal, and on Eighth Avenue to the west. A ticket booth selling discounted Broadway and off-Broadway shows. However, the cheaper tickets aren't the only attraction, as the back of the booth is a large, red-lit glass staircase facing Times Square, which serves as a set of bleachers and offers an excellent opportunity to get above the street and just watch the crowds and flashing signs. Above the booth is a video screen with a live feed of the top step, giving you a chance to appear (if only briefly) on one of the many signs in Times Square. Originally the second-tallest building in the world when it opened in 1905, One Times Square was constructed to be the headquarters for The New York Times, a function it would serve for less than ten years. The annual Times Square ball drop is performed from the roof of this building. And you can't miss the famous Dow Jones news and sports zipper (the first news ticker in the world) attached to its lower facade.

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.
