The May Pyramid, or Piramide de Mayo, was the first monument built in Buenos Aires and it was to commemorate the revolution of 1810. It was built the following year. Its size was increased later by adding bricks and a statue to the top. The original pyramid sits safely inside of the new monument. The monument is located in May Park, the country's political center.
The Two Congresses Park is filled with a series of small squares, each with their own monument. One of these monuments is the "Monument of Two Congresses," which is in the middle of the main square. Others include sculptures of Ricardo Balbin and Mariano Moreno, and a replica of the famous "The Thinker" by Rodin.
Still referred to by most as the Torre de los Ingleses, or the British Tower, this monument was officially renamed Torre Monumental, or Monumental Tower, after the Falklands war in 1982. It was built by British residents in commemoration of the centennial of the Revolution of May. It was inaugurated on May 24, 1916. All the building materials, save the sand and water, were brought over from England.
This square was known as the "Campo de la Gloria," or Battlefield of Glory in the early 1800s. It was the location of the battle between British invaders and the people of Buenos Aires. Many sculptures and monuments fill the square, most notably the "General Jose de San Martin Monument" and the "Monument Honoring the Soldiers, Sailors and Airmen who died during the Malvinas Islands war."
Built and inaugurated in 1936 by Argentine architect, Alberto Prebisch, the Obelisk stands 67 meters high. Some would say it resembles the Washington Monument in D.C. Each of the four sides of the Obelisk commemorates a separate moment in the city's outstanding history.
Carta Magna and the Four Argentine Regions is more commonly know as El Monumento de los Espanoles, or Monument of the Spaniards. It was gifted from the Spanish community and was made from marble and bronze. The sculpture that sits atop the monument represents the "Republic."
