Being the second largest sea port of Bangladesh it plays a pivotal role for our country’s economy.There are a good number of prawn hatcheries in Mongla.

In mid-15th century, a Muslim colony was founded in the inhospitable mangrove forest of the Sundarbans near the seacoast in the Bagerhat district by an obscure saint-General, named Ulugh Khan Jahan. He was the earliest torch bearer of Islam in the South who laid the nucleus of an affluent city during the reign of Sultan Nasiruddin Mahmud Shah (1442-59), then known as 'Khalifalabad' (present Bagerhat). Khan Jahan aborned his city with numerous mosques, tanks, roads and other public buildings, the spectacular ruins of which are focused around the most imposing and largest multidomed mosques in Bangladesh, known as the Shait-Gumbad Masjid (160'X108'). The stately fabric of the monument, serene and imposing, stands on the eastern bank of an unusually vast sweet-water tank, clustered around by the heavy foliage of a low-laying countryside, characteristic of a sea-coast landscape. So in the year 1459 the great Azam Ulugh Khan Jahan established this mosque, which called Shat Gambuj Mosjid. In Bengali Shat means the number 60. Though it is called Shat Gambuj Mosjid, actually the numbers of Gamboj in the mosque are 81. The mosque roofed over with 77 squat domes, including 7 chauchala or four-sided pitched Bengali domes in the middle row. The vast prayer hall, although provided with 11 arched doorways on east and 7 each on north and south for ventilation and light, presents a dark and somber appearance inside.
It is divided into 7 longitudinal aisles and 11 deep bays by a forest of slender stone columns, from which springs rows of endless arches, supporting the domes. Six feet thick, slightly tapering walls and hollow and round, almost detached corner towers, resembling the bastions of fortress, each capped by small rounded cupolas, recall the Tughlaq architecture of Delhi.
The general appearance of this noble monument with its stark simplicity but massive character reflects the strength and simplicity of the builder. This mosque is 160 ft long and 108 ft. in its width. This is one of the most beautiful archeological and historical Mosque in Bangladesh made by red burn mud.
