Why are Traditional Houses in the Algarve White?

The traditional houses of the Algarve are easily recognized by their white walls, clay roofs, decorated chimneys and colorful details. This image became one of the symbols of the region, but the choice of white was not just aesthetic.

For centuries, lime was used for practical, climatic and hygienic reasons, helping Algarve homes adapt to the hot summers of southern Portugal.

Why were Algarve houses painted white?

The main reason is related to heat. White surfaces reflect a significant portion of solar radiation, absorbing less heat than dark walls.

In a territory characterized by long hours of sunlight and high temperatures in the summer, whitewashing the facades helped keep the interior of the houses cooler.

What is whitewashing?

Whitewashing consists of applying a mixture of lime and water to walls and facades. It was a common practice in several Mediterranean regions and was part of the regular maintenance of homes.

In addition to providing the characteristic white color, lime had properties that helped in the conservation and hygiene of walls.
