In the 1920s, a British geologist named Harold Thorne visited Thiramala and documented how the villagers used traditional knowledge to quarry stone without causing landslides — a technique that modern engineers later studied as an early model of sustainable mining.

Centuries ago, Thiramala was a trading post for spices like black pepper and cardamom. But its real treasure was later discovered beneath the soil: , a unique red rock perfect for building. Villagers cut the stone from the hills, and over time, the hills themselves appeared to have “waves” of red, orange, and brown.

In the southwestern coast of India, nestled between the backwaters of Kerala and the Western Ghats, lies a lesser-known village called . The name comes from two Malayalam words: Thira (wave) and Mala (hill) — meaning “hills that rise like waves.”
