AbstractCreated in the central and western part of Brazil to be the new capital of the country, Brasília is a definitive example of modernist twentieth-century urbanism and was named a Cultural Heritage Property by UNESCO in 1987. It was built in just four years (1956–60), following a design by urbanist Lúcio Costa and architect Oscar Niemeyer. However, despite the worldwide recognition of the architectural value of the buildings, the extensive use of white marbles as cladding is scarcely mentioned in the literature. Surveys conducted in this work indicate that the majority of the marble was sourced primarily from the Italva region (Rio de Janeiro), and probably, in minor quantities, from Cachoeiro de Itapemirim region (Espírito Santo). Available technological data for rocks from those regions revealed their suitable engineering properties as natural stone. Currently, although most of the slabs still remain on the buildings, the preservation of this world cultural heritage is urgent, as pointed out by UNESCO. For this purpose, the potential designation under the name the Brasília white marbles as a Global Heritage Stone Resource would be very beneficial, encouraging the availability of these natural stones for conservation and restoration.
