Why Is The Floor of Masjid al-Haram Always Cool – Even in Scorching Heat?

For anyone who has set foot in Masjid al-Haram in Makkah, there’s often one curious detail that leaves a lasting impression—how does the white marble floor surrounding the Kaaba stay cool, even under the blazing desert sun?

Many visitors from around the world have experienced it: walking barefoot in the open courtyard on a sweltering day, expecting the ground to be scorching hot… only to be surprised by the cool touch beneath their feet.

Some have speculated that there must be some sort of cooling system underneath—perhaps a network of chilled water pipes hidden beneath the marble. But is that really the case?

Not high-tech cooling: Just a clever natural choice

According to an article published by Arab News, the answer isn’t in advanced engineering or modern technology. The secret actually lies in the type of marble chosen for the flooring.

The marble used at Masjid al-Haram is known as Thassos marble, and it comes all the way from the island of Thassos, located in the eastern part of Greece, near the Aegean Sea. This particular type of marble wasn’t selected just for its bright, gleaming appearance—it also has remarkable natural properties.

Unlike regular marble, Thassos marble is known for its ability to reflect sunlight rather than absorb it. Its pure white colour helps bounce off the sun’s rays, preventing the floor from heating up as quickly. In addition, the crystal structure within the marble helps it retain coolness for longer periods, even in extreme heat.

Comfort for millions of pilgrims

For the millions of worshippers who perform tawaf or pray in the vast open areas around the Kaaba, this cool flooring is more than just a marvel of architecture—it’s a true blessing. It provides physical relief, minimises the risk of heat stress, and allows pilgrims to focus on their spiritual experience in greater comfort.

Even though modern technology plays a major role in the maintenance and expansion of Masjid al-Haram, the thoughtful choice of natural materials like Thassos marble shows the care and attention given to every detail—especially when it comes to the well-being of those who visit.
