South Indian architecture began with the Pallavas in the 7th century, reaching its peak under the Cholas between the 9th and 13th centuries. Notable examples of Pallava architecture include the rock-cut temples of Mahabalipuram, especially the Seven Rathas. Chola architecture is known for its tall temple towers called gopurams and temples built in the Dravidian style with multiple storeys. The Brihadeeswarar Temple at Thanjavur is a prime example, as are the temples at Kanchipuram and Gangakondacholapuram. Vijayanagara architecture included the ruins at Hampi and the Virupaksha Temple complex.
