Adina Mosque is Pandua's heavyweight monument. Built under Sultan Sikandar Shah in the 14th century, it was conceived on an imperial scale: a huge courtyard, arcaded walls, reused stone, and the tomb chamber of the sultan who commissioned it.
Much of the roofing is gone, which makes the ruin feel even larger. Look for the mix of brick, stone, Islamic geometry, and older Bengali motifs worked into the fabric of the building.
