The walls of our houses are painted with lime white and in their stripes we use the typical Alentejo blue or yellow. Lime comes from limestone, which is mixed with water for later use. Lime has a characteristic shine and texture that indicate from a distance that we are looking at an Alentejo village. In addition to the aesthetic qualities, lime contributes to the capture of carbon dioxide (during lime solidification, carbonation occurs).
The wall stripes are normally applied in the near ground areas or around the windows. In the case of blue, traditional knowledge suggests that it began being used in the village of Santa Susana, in Alcácer do Sal. According to the villagers here in São Brás do Regedouro, the stripes near the ground are strategically painted because they are the areas of the walls most subject to getting dirty (especially in the rainy season), and it is easier to repaint only those stripes, than to paint a house all in white again.
