Rock-cut temples were hewn out of huge rocks. The earliest rock-cut temples were excavated in western Deccan in the early years of the Christian era. The chaitya at Karle with fine high halls and polished decorative wall is a remarkable example of rock-cut architecture. The Kailash temple at Ellora built by the Rashtrakutas and the ratha temples of Mahabalipuram built by the Pallavas are other examples of rock-cut temples. Most probably the stability and permanence of rocks attracted the patrons of art and builders who decorated these temples with beautiful sculptures.
