Monasteries are buildings or complexes that house monastics such as monks and nuns. A typical monastery includes places for prayer, living quarters, and work spaces. Buddhist monasteries in India include Nalanda Vihar, Nasik Vihar, and the three-storeyed viharas at Ellora. Nalanda Vihar featured temples and monasteries arranged systematically with sculptures and artifacts. Nasik Vihar included cave dwellings with halls and cells. The three-storeyed viharas at Ellora had large courtyards surrounded by cells and halls and included some of the finest cave architecture and artwork.
