Ongoing conservation efforts at a 12th-century Shiva Temple in the Malwa region of Madhya Pradesh have led to a surprising discovery regarding medieval construction techniques. While reinforcing the temple's shikhara (spire), restoration experts identified a layer of organic mortar infused with pulverized sandalwood and medicinal herbs, a practice previously known only through ancient Vastu Shastra texts.
The Bhumija style architecture, characterized by its star-shaped ground plan and miniature spires, has remained structurally stable for centuries. Researchers believe the aromatic additives were used not only for their sacred properties but also as a natural preservative and pest repellent for the stone joints. This finding provides new insights into the chemical engineering used by the Paramara dynasty builders to ensure the longevity of their sacred monuments.
