Sadna Qasai Mosque

The Sadna Qasai Mosque is a disused mosque in Sirhind, Punjab, now in ruins and listed as a state protected monument. Its date is uncertain: scholars place it at the end of the Delhi Sultanate or the start of the Mughal period, and it may have been raised by Humayun to mark his win at the Battle of Sirhind in 1555. It takes its name from Bhagat Sadhana. In 2025 a public-interest case seeking its preservation went before the Punjab and Haryana High Court.

The building has a central wing, probably the only part used as the prayer hall, flanked by two side wings, fronted by five arched openings beneath a parapet almost 10 metres high. It once carried five domes; the large central one has collapsed. Inside, the western wall of the central wing has three prayer niches, the central one painted with later floral designs, while the side wings, which lack niches, are split into domed bays. A square ablution tank stands in front.
