Jamdani was originally known as Dhakai named after the city of Dhaka, one of many ancient textile weaving centers in Bengal region.[5] Under the Mughal Empire the Persian term Jamdani came to be in popular use, since it was the court language of the Mughals. Jamdanis are popularly known as Dhakai Jamdani or simply Dhakai. The earliest mention of jamdani and its development as an industry is found into Dhaka, Bangladesh. Jamdani is a hand loom woven fabric made of cotton, which was historically referred to as muslin. The Jamdani weaving tradition is of Bengali origin. It is one of the most time and labor-intensive forms of hand loom weaving, and is considered one of the finest varieties of muslin, and the most artistic textile of Bangladeshi weavers. Traditionally woven around Dhaka and created on the loom brocade, jamdani is rich in motifs. In the first half of the nineteenth century, James Taylor described the figured or flowered jamdani; in the late 19th century, T. N. Mukharji referred to this fabric as jamdani muslin. Whether figured or flowered, jamdani is a woven fabric in cotton. This is a supplementary weft technique of weaving, where the artistic motifs are produced by a non-structural weft, in addition to the standard weft that holds the warp threads together. The standard weft creates a fine, sheer fabric while the supplementary weft with thicker threads adds the intricate patterns to it. Each supplementary weft motif is added separately by hand by interlacing the weft threads into the warp with fine bamboo sticks using individual spools of thread. The result is a complex mix of different patterns that appear to float on a shimmering surface. The pattern is not sketched or outlined on the fabric, but is drawn on a graph paper and placed underneath the warp. Jamdani is a fine muslin cloth on which decorative motifs are woven on the loom, typically in grey and white. Often a mixture of cotton and gold thread was used.

Built in 1519, the graceful, single-domed Goaldi Mosque is the most impressive of the few extant monuments of the old capital city, and a good example of pre-Mughal architecture. This mosque is one of the few remnants from the Sultanate period in Sonargaon, during the reign of Sultan Hussain Shah in 925 Hijri (1519 AD). It was built by Mulla Hizabar Akbar Khan in the early 16th century, during the reign of Alauddin Husain Shah at a place called Goaldi – half a mile northeast of Panam village in Sonargaon. Sonargaon was the administrative center of medieval Muslim rulers of East Bengal. It became as the capital of Bengal during Isa Khan’s ruling. The area falls under present-day Narayanganj District, Bangladesh. This mosque is more elegant and ornate in comparison to the earlier Sultanate mosques at Bagerhat.

The baroque decoration and the elaborated painting on the plaster of the building are really eye catching.
