This is one of the buildings which, with the Palácio de Planalto and the Federal Supreme Court, configure the Praça dos Três Poderes, but unlike the other two it does not house a unitary programme, being required to accomodate two separate assemblies: the House of Deputies and the Senate. Its privileged situation, at the final point of the perspective along the monumental axis, which makes this one of the city's major landmarks, demanded the creation of a building that would communicate its force over considerable distances. This is accomplished by translating the duality of functions into a duality of architectonic expression. The parliament building marks out a long horizontal line broken only by the block of offices, and from a distance the complex appears as a continuation of the square, on which the cupolas of the House of Deputies and the Senate seem to rest. The office towers stand out as notable landmarks, and assume the character of decisive elements in the city's skyline.
