Bagha Mosque is one of the ancient architectural heritages situated in the small town of Bagha, within the Rajshahi District in Bangladesh. Constructed in 1523 by the order of Sultan Nasiruddin Nasrat Shah, a prominent ruler of the Bengal Sultanate, the mosque is renowned for its magnificent terracotta ornamentation. The mosque, built with baked bricks, is a fine specimen of the Bengal style of architecture. The exteriors exhibit intricate terracotta designs depicting floral motifs and geometric patterns, which reflect the skill and aesthetic sense of the artisans of that era. Over the centuries, the mosque has overcome damages caused by natural calamities, and renovation work has been carried out to preserve its historical significance and beauty. With its tranquil environment and historical significance, it is not just a place of worship but also a site of attraction for tourists and history enthusiasts. The mosque is surrounded by a large courtyard and has a water tank that was historically used for ablutions before prayers. Today, it stands as a testament to the rich cultural heritage and marvelous artistry of the Sultanate period in Bangladesh.
