Konark’s Sun Temple, a UNESCO World Heritage Site, is a breathtaking example of India’s architectural brilliance. Built in the 13th century by King Narasimhadeva I of the Eastern Ganga Dynasty, the temple is dedicated to Lord Surya, the Sun God. Located in Puri district, Odisha, this magnificent structure is designed as a massive chariot with 12 pairs of intricately carved wheels, symbolizing the celestial chariot of the Sun God.
