he Palacio da Alvorada (Portuguese pronunciation: [paˈlasju dɐ awvoˈɾadɐ]) is the official residence of the President of Brazil. It is located in the national capital of Brasilia, on a peninsula at the margins of Paranoa Lake. The building was designed by Oscar Niemeyer and built between 1957 and 1958 in the modernist style. It has been the residence of every Brazilian president since Juscelino Kubitschek. The building is listed as a National Historic Heritage Site.
The building was initially referred to as the "Presidential Palace". The name "Palacio da Alvorada" ("Palace of Dawn") comes from a quote by Juscelino Kubitschek:"Que e Brasilia, senao a alvorada de um novo dia para o Brasil?""What is Brasilia, if not the dawn of a new day for Brazil?"
The palace became symbol of the modern movement of Brazilian architecture, of cultural and technical progress of the country. Its columns became symbol of the city, and are present in the flag and coat of arms of the capital of the Republic.
Niemeyer used a combination of marble, glass and water. The symmetry of the marble columns combines with the reflex in the glass facade and in the water mirror. The columns touch the ground in one vortex, passing an impression of lightness.
