Description

The architectural heritage of the historical city centre of Sao Luis of Maranhao, located in the northeast region of Brazil, has approximately 5,600 registered buildings, out of which 1,400 were included in the UNESCO World-Heritage List in December 1997. The architectural heritage of 18(th) and 19(th) centuries is made up of sobrados (ground storey for commercial and upper storeys for residential use), solares (constructions with distinguished finishing, exclusively for residential use by privileged families) and single-storey constructions where poorer families used to live. Different construction systems can be found in the same building of the historical city centre. It is common to have structural walls made of stone masonry with lime mortar (in rare cases made of adobe) and interior partition walls made of pau-a-pique (also called taipa de mao), cruz de Santo Andre (resembling the gaiola pombalina style) and tabique. Therefore, in the majority of the internal partition walls earth-based masonry is found, which, in many interventions, was replaced by contemporary techniques. This article discusses the earth based masonry typologies found in the buildings from the 18(th) and 19(th) centuries in the historical centre of Sao Luis belonging to the registered areas at federal and state level. It characterizes the different typologies of the earth-based masonries, analysing the historical, cultural and socio-economic period when they were used in the region. It is designed to contribute to the scientific and technological knowledge of the earth-based masonry systems used in Sao Luis in the 18(th) and 19(th) centuries and thus to the preservation and rehabilitation of its heritage.
