Explanation: During the Satavahana phase, many chaityas (sacred shrines) and viharas (monasteries) were cut out of the solid rock in the north-western Deccan or Maharashtra with great precision and skill.

• The Karle Chaitya in the western Deccan belongs to this era. The Nashik inscriptions of Nahapana and Gautamiputra Satakarni, which are on the walls of the three viharas , is another important architectural site belonging to this period.
• The official language of the Satavahanas was Prakrit, though the script was Brahmi.
• One famous Prakrit text, Gathasattasai, is attributed to a Satavahana king called Hala, which consisted of 700 verses all written in Prakrit.
