<P> During the colonial era, the Ajanta site was in the territory of the princely state of the Hyderabad and not British India . In early 1920s, the Nizam of Hyderabad appointed people to restore the artwork, converted the site into a museum and built a road to bring tourists to the site for a fee . These efforts resulted in early mismanagement, states Richard Cohen, and hastened the deterioration of the site . Post-independence, the state government of Maharashtra built arrival, transport, facilities and better site management . The modern Visitor Center has good parking facilities and public conveniences and ASI operated buses run at regular intervals from Visitor Center to the caves . </P> <P> The Ajanta Caves, along with the Ellora Caves, have become the most popular tourist destination in Maharashtra, and are often crowded at holiday times, increasing the threat to the caves, especially the paintings . In 2012, the Maharashtra Tourism Development Corporation announced plans to add to the ASI visitor centre at the entrance complete replicas of caves 1, 2, 16 & 17 to reduce crowding in the originals, and enable visitors to receive a better visual idea of the paintings, which are dimly - lit and hard to read in the caves . </P> <P> The caves are carved out of flood basalt rock of a cliff, part of the Deccan Traps formed by successive volcanic eruptions at the end of the Cretaceous geological period . The rock is layered horizontally, and somewhat variable in quality . This variation within the rock layers required the artists to amend their carving methods and plans in places . The inhomogeneity in the rock have also led to cracks and collapses in the centuries that followed, as with the lost portico to cave 1 . Excavation began by cutting a narrow tunnel at roof level, which was expanded downwards and outwards; as evidenced by some of the incomplete caves such as the partially - built vihara caves 21 through 24 and the abandoned incomplete cave 28 . </P> <P> The sculpture artists likely worked at both excavating the rocks and making the intricate carvings of pillars, roof and idols; further, the sculpture and painting work inside a cave were an integrated parallel tasks . A grand gateway to the site was carved, at the apex of the gorge's horseshoe between caves 15 and 16, as approached from the river, and it is decorated with elephants on either side and a nāga, or protective Naga (snake) deity . Similar methods and application of artist talent is observed in other cave temples of India, such as those from Hinduism and Jainism . These include the Ellora caves, Ghototkacha caves, Elephanta Caves, Bagh Caves, Badami Caves and Aurangabad Caves . </P>
