Uncovering the Secrets Behind Lisbon's Gravel Roads: A Guide to Calada Portuguesa

Stripes of Stone: Lisbon is known not just for its historic beauty and charm, but for an interesting feature on its streets that sets it apart from other cities. Residents and visitors alike often ponder the reason for these small stones covering many of Lisbon's roads.

What Are Lisbon’s Streets Filled with?

Technically, the small stones you'll see are stone setts, cobbles, or pavé. This road surfacing technique is common in many parts of Europe, but Portugal seems to use it extensively in its urban areas. The stones serve multiple purposes and have an interesting history.

A Natural and Sustainable Alternative

One of the main reasons for using stone setts is their sustainability. If an existing road needs to be excavated for repairs or improvements, simply pile up the stones, dig up the road, perform the necessary work, and then replace the stones. In contrast, traditional oil-based road surfaces require more extensive and less sustainable methods. Stone setts also naturally limit traffic speed, adding another layer of safety for pedestrians and cyclists.

Cultural Heritage: Calada Portuguesa

Calada Portuguesa, a form of stone mosaic art, has its roots in Lisbon and was popularized from the 1840s. This unique art form not only decorates squares and other public areas but also extends to other Portuguese-speaking countries such as Brazil, adding a distinctive touch to urban landscapes.

Historical Significance of Lisbon Streets

Interestingly, the use of these stones dates back to the 15th century. Originally, they were used as ballast in ships. When the ships returned and the stones were no longer needed, they were repurposed for pavements. This historical practice continues to shape Lisbon's urban infrastructure.
