The Ushmanpur Jame Mosque, popularly known as the ‘Gayebi’ (Hidden or Mystical) Mosque, stands as a silent witness to 500 years of Islamic history in the Sylhet region. Built during the Sultanate period between 1530 and 1540 AD, this architectural marvel is currently at the center of a struggle between modernization and heritage preservation.

The Legend of the ‘Gayebi’ (Hidden) Mosque
The term ‘Gayebi’ (meaning hidden from sight or appearing from the unseen) stems from local folklore. It is said that the mosque was lost for generations, buried under dense jungle and hillocks. When locals eventually cleared the land and rediscovered the structure intact, they named it the ‘Gayebi’ mosque, believing it to be a mystical gift from the unseen.

Architectural and Academic Significance
The mosque is a classic example of Bengal’s Sultanate architecture. Measuring 32 feet by 32 feet, its square base transitions into a stunning circular dome. The interior is decorated with ancient motifs and terracotta-style craftsmanship.

The historical importance of this mosque is recognized globally. Prof. Dr. Perween Hasan (Harvard University) highlighted this site in her seminal work “Sultans and Mosques: The Early Muslim Architecture of Bangladesh.” Furthermore, research from the Chinese University of Hong Kong (2008-09) by Nujaba Binte Karim has categorized it as a vital link in the grammar of Sultanate-era Islamic art.

A Heritage at Risk
Despite its profound history, the mosque is facing an existential threat. Due to a growing local population, the mosque management committee attempted to demolish the ancient structure in 2016 to build a larger modern building. While intense protests from heritage lovers and local residents temporarily halted the demolition, the threat remains.

Historical documents reveal that in 1801, Persian deeds (currently preserved in the District Collectorate) were issued by the administration of Nawab Alivardi Khan and later Subahdar Najmuddin Ali Khan to grant land for the mosque’s upkeep. However, without official status as a protected monument, this 5-century-old treasure remains vulnerable to unplanned expansion.

The Call for Preservation
Local historians argue that instead of demolition, the mosque should be preserved as a protected site, with any necessary new prayer facilities built adjacent to it. As part of a new digital mapping initiative, researchers are now working to document the 'Gayebi' mosque’s architecture to ensure its history is never lost to the sands of time.
