The main stupa dates to the 9th century AD and was likely built on the site of an earlier, Gupta-era stupa. Seals were found bearing the legend "Sri Ratnagiri Mahavihariya Aryabikshu Sanghasya," which helped identify it. Prominent, well-persevered standing statues of the bodhisattvas Vajrapani and Padmapani can be found in niches in a portico. Monastery No. 2 features a central paved courtyard fla
nked by a pillared veranda around which are eighteen cells, a central shrine featuring an image of Shakyamuni in varada mudra flanked by Brahma and Sakra, and elaborately ornamented entrance porticos. According to Amit Jha, a lecturer in the Department of History at Sri Aurobindo College, Delhi University, "Ratnagiri comprises two magnificent monasteries, also rebuilt more than once. One of them was double-storyed and had an extensive courtyard with two-sides of it having a number of cells for habitation of monks. Besides, we have archaeological remains of six temples, thousands of small stupas, 1386 seals, myriad sculptural relics and architectural pieces of daily use. The largest stupa was 47 feet (14 m) square and 17 feet (5.2 m) high surrounded by four minor stupas. There are hundreds of miniature votive stupas decorated with lotus, petal and beaded tassels."[3]
A museum now located on the site displays statuary featuring Tara, Avalokiteshvara, Aparajita, and Hariti have also been found, all in prototypical of Gupta style.
