The Vijayanagar Empire lasted from 1336 to 1646 AD and was an important Hindu empire in South India. It saw significant growth and expansion under rulers like Krishnadeva Raya in the 15th-16th centuries. The empire developed impressive architecture including temples, palaces, and tanks that blended elements of local South Indian styles with some Islamic influences. Key architectural features included intricately carved pillars, large temple enclosures, and shrines dedicated to Tamil saints. The Vijayanagar style of architecture went on to influence temple building in South India even after the fall of the empire in the 16th century.
