Technology Behind Ayodhya Ram Temple Construction Unveiled

The construction technology of the Ayodhya Ram Temple has drawn significant attention at the India International Trade Fair (IITF) in New Delhi. As the temple prepares for the hoisting of the saffron flag, marking its completion, the techniques employed in its building—particularly the absence of iron and cement—have been detailed by experts at the event. Since the consecration of the idol of Lord Ram, over 55 million devotees have visited Ayodhya to experience the temple’s architectural magnificence.

At the IITF, the National Institute of Rock Mechanics showcased a model of the Ram Temple along with the actual stones used in its construction. Yogendra Singh, a senior scientist at the institute, emphasized the remarkable characteristic of the stones: their ‘immortality.’ He explained that the temple incorporates stones that are thousands of years old, constructed entirely with stone blocks, and without the use of iron or cement.

Singh highlighted that the foundation of the Ram Temple is primarily composed of granite, while sandstone was selected for its external detailing. These stones were sourced from the Pindwara and Bansi Mountains in Rajasthan. The temple’s interior features a white surface made from high-quality marble obtained from Makrana, Rajasthan. The idol of Lord Ram itself is crafted from fine-grade, high-strength granite.

The absence of iron and cement in such a large structure raises questions about its stability. Singh pointed out that ancient Indian construction methods were utilized, specifically the technique of interlocking stones. Each stone was designed to fit naturally with its neighbors, creating a robust structure. Instead of iron, copper clamps were used to secure the stones during the grooving process.

To ensure the temple’s durability, extensive measures were taken regarding the lifespan of the boulders employed. Singh noted that the granite used for the foundation is resistant to weather conditions. “State-of-the-art technical standards were applied to verify the quality of each stone block,” he said. Before installation, every block was tested for strength and durability, with a particular focus on detecting any internal cracks, known as micro-cracks, that could compromise the structure.

Core samples were extracted to measure the uniaxial compression strength (UCS) of the rocks. Advanced techniques, including ultrasonic velocity testing, were employed to detect any cracks within the blocks. Singh explained that since the geology of each stone varies, distinct testing methods were necessary for different types—such as granite and sandstone—ensuring that each material met the rigorous standards required for the temple’s construction.

The innovative techniques highlighted at the IITF reflect a blend of traditional craftsmanship and modern engineering principles, showcasing how ancient methods can inform contemporary construction practices. As the Ayodhya Ram Temple approaches its completion, it stands not only as a spiritual landmark but also as a testament to the enduring legacy of Indian architectural heritage.
