Thanale Caves

Thanale Caves, also known as Nadsur Caves, are a group of ancient Buddhist rock-cut excavations located in Thanale Village, Sudhagad Taluka, Raigad District, Maharashtra. Dating to the first century B.C., specifically between 70 and 50 B.C., they are among the oldest rock-cut caves in India. The site comprises viharas, chaityas, and stupas situated along an ancient trade route from Chaul. Access requires a trek through dense forest from Thanale village.

Visitors can expect a moderate trek of approximately 2.6 km through dense forest and mountainous terrain to reach the caves. The site features 23 rock-cut excavations including two chaityas, two stupas, and multiple viharas carved into a volcanic trap cliff. Cave 7 is the largest and displays decorative Buddhist rail motifs and chaitya arches. There are no facilities at the site, and visitors must carry their own food and water. The trail may involve crossing streams during the monsoon season.

The caves date to the first century B.C., with paleographic evidence suggesting excavation between 70 and 50 B.C. They represent one of the earliest phases of rock-cut architecture in India and were strategically located on the ancient Chaul trade route connecting the Deccan plateau to Konkan ports. The site contains inscriptions mentioning donor names and served as a Buddhist monastic complex.

Thanale Caves are significant as an early example of Hinayana Buddhist rock-cut architecture in Maharashtra. The site functioned as a monastery for Buddhist monks and includes prayer halls (chaityas) and residential cells (viharas). It is listed as a Protected Monument by the Archaeological Survey of India.
