Ananda Vihar, also known as Ananda Vihar or Ananda Raja Bari, is an important archaeological site in the Mainamati-Lalmai region of Comilla district, Bangladesh. This remarkable monastery complex, associated with the early medieval Buddhist tradition of southeastern Bengal, provides insight into the religious, architectural and intellectual traditions that flourished in the region more than a thousand years ago.
The monastery is generally attributed to Sri Anandadeva of the Adi Devavanma dynasty and is believed to have been built in the late 7th or early 8th century CE. Archaeological excavations have revealed a large, square monastery courtyard, rows of monks' rooms, a central shrine, and evidence of high-quality brick construction. Artifacts found with the site include bronze sculptures, terracotta plaques, silver coins, pottery, and a copper inscription.
Unlike the easily accessible Shalvan Vihar , Anand Vihar is located within the Mainamati Cantonment area. Visitors should not assume that these ruins are open to general tourists. Prior permission is required from the concerned Cantonment authorities and entry should be confirmed before making travel arrangements.
Anandavihar is an important part of the larger archaeological landscape of Mainamati for tourists interested in the history of ancient Bengal. Although direct visits are not possible, the nearby Mainamati Museum and other heritage sites open to the public provide an opportunity to explore the Buddhist past of the region.
