This is the last weekend of the Museum of the City of New York's dazzling exhibit, The Greatest Grid: The Master Plan of Manhattan, 1811-2011. The show celebrates the 200th anniversary of NYC's street grid design and shows amazing maps and photographs of the city.

There's an original hand-drawn map of New York's planned streets and avenues, which was prepared by NYC's planning commission in 1811. You'll also see "rare historic maps, photographs and prints of the evolution of the city's streets, and original manuscripts and publications that document the city’s physical growth, the exhibition examines the grid’s initial design, implementation, and evolution." Look at what Union Square looked in 1849!
