English: Excavated in April 1882 by Bhagwan Lal Indraji, The ruins of a Buddhist Stupa was found. Nala Sopara is accepted by scholars as the Suparaka or Supparak of ancient India and was a busy trade centre and an important seal of Buddhism. It was also one of the administrative units under the Satavahanas and is mentioned in the inscriptions of Karle, Nashik, Naneghat, and Kanheri. From the centre of the stupa (inside a brick built chamber) a large stone coffer was excavated which contained eight bronze images of Maitreya Buddha which belong to the c. 8th-9th century CE. This coffer also enclosed relic caskets of copper, silver, stone, crystal and gold, along with numerous gold flowers and fragments of a begging bowl. A silver coin of Gautamiputra Satakarni (Satavahana) was also found from the mound. The Bombay Provincial Government presented the Sopara relics to the Asiatic Society of Bombay. The coins and the artifacts found during the excavations at the site of this ancient town can still be viewed in the Asiatic Society, Mumbai museum.
