Grand Army Plaza should actually be on the list of sites to visit when it comes to New York. The great attraction of the square is the arch which is located in the main entrance of the Prospect Park, one of the largest parks and beautiful in New York. Much more calm that the Central Park. In his visit to the monument you can take the opportunity to visit and explore the Art Museum or the Botanical Garden in Brooklyn which are just a few steps, in the night is a nice place to go when the lights are on, you can walk, run, or bike through the park. You can enjoy the spectacle of sea lions in the Prospect Park Zoo or read a book in the fifth largest library of the United States, the Brooklyn Library.
