Shat Gambuj Mosque is the largest of the Sultanate mosques in Bangladesh and one of the most impressive Muslim monuments in the whole of the Indian subcontinent. It is ascribed to one Khan Al-Azam Ulugh Khan Jahan, who conquered the greater part of southern Bengal and named the area khalifatabad in honour of the reigning Sultan Nasiruddin Mahmud shah (1435-59). 

The mosque is unique in the sense that it has 60 pillars that support the roof, with 77 low height domes. The 4 towers at 4 corners have smaller domes on the roof as well. The vast prayer hall has 11 arched doorways on the east and 7 each on the north and south for light and ventilation. It has 7 aisles running along the length of the mosque and 11 deep curves between the slender stone columns. These columns support the curving arches created by the domes. The thickness of the arches is 6 feet and have slightly narrowing hollow and round wall.

The west wall in the interior has 11 ‘mihrabs’ The interior and the exterior of the mosque give a view of rather plain architecture but the interior western wall of the mosque is’ beautifully decorated with terracotta flowers and foliage. Besides being used as a prayer hall the mosque was also used as the court of Khan Jahan Ali. Now it is one of the greatest tourist attractions and best architectural beauties of Bangladesh.
