Most famous of the Buddhist caves is cave 10, a chaitya hall (chandrashala) or 'Vishwakarma cave', popularly known as the "Carpenter's Cave". Beyond its multi-storeyed entry is a cathedral-like stupa hall also known as chaitya, whose ceiling has been carved to give the impression of wooden beams. At the heart of this cave is a 15-foot statue of Buddha seated in a preaching pose. Amongst other Buddhist caves, all of the first nine (caves 1–9) are monasteries. The last two caves, Do Tal (cave 11) and Tin Tal (cave 12) have three stories.
