The term "Mahavihara" refers to a significant type of Buddhist monastery, particularly in the Theravada tradition. These monasteries serve as centers for learning, meditation, and community life for monks and laypeople. The most famous Mahavihara is located in Anuradhapura, Sri Lanka, which was a major center of Buddhist scholarship and practice. Mahaviharas are characterized by their large size and comprehensive facilities, including meditation halls, living quarters for monks, and spaces for teaching. They often play a crucial role in preserving and transmitting Buddhist teachings and practices, making them vital to the cultural and spiritual heritage of the regions where they are found.
