OBELISK - ARGENTINA
Built in 1936 to commemorate the 25th anniversary of the city's creation, Buenos Aires' massive obelisk is situated in the middle of one of the largest roads in the world, the Avenida de 9 Julio, and dominates the city's landscape. The monument designed by Alberto Prebisch, is 67m (220 ft) in height and only 49 square meters (527 sq. ft.) at the base. In the interior a 200-hundred-step stairway is used to perform maintenance jobs from the top. The obelisk brightens with white lights at night, although, the gleams of surrounding neon billboards is what gives the area its unique and colorful glow.
