According to the Mahaarashtran Tourist Information Site:

"Over time, the bhikshus enlarged their rock-cut Caves and in each group of viharas one was set aside as a chapel for meditation and the performance of prayer rituals. A stupa, now a votive memorial, was carved at the inner end and the arrangement of columns allowed a circumambulatory passage around it. Over the entrance was the characteristic arch in the shape of a pipal leaf. Originally simple and even severe, as at Bhaja, the chaitya developed into an impressive shrine like the magnificent Karla chaitya of the 2nd century AD -- an inscription here claims that it is the finest in ancient India..."
