Hampi - Ancient and medieval monuments, a UNESCO World Heritage Site in Karnataka, India

"Hampi or Hampe, also referred to as the Group of Monuments at Hampi, is a UNESCO World Heritage Site located in east-central Karnataka, India. It became the pilgrimage centre of the Hindu religion. It was the capital of the Vijayanagara Empire in the 14th century. Chronicles left by Persian and European travellers, particularly the Portuguese, say that the Hampi state was a prosperous, wealthy and grand city near the Tungabhadra River, with numerous temples, farms and trading markets. By 1500 CE, Hampi-Vijayanagara was the world's second-largest medieval-era city after Beijing, and probably India's richest at that time, attracting traders from Persia and Portugal. The Vijayanagara Empire was defeated by a coalition of Muslim sultanates; its capital was conquered, pillaged and destroyed by sultanate armies in 1565, after which Hampi remained in ruins. - Wikipedia"
