Choto Shona Mosque (Bengali: ছোট সোনা মসজিদ, Small Golden Mosque) is located in Chapai Nawabganj district of Bangladesh. The mosque is situated about 3 km south of the Kotwali Gate and 0.5 km to the south-east of the Mughal Tahkhana complex in the Firozpur Quarter.
The mosque was built during the reign of Sultan Hussain Shah, between 1493 and 1519. The fifteen domes of the mosque were once gilded, giving the mosque the name of Choto Shona Masjid (Small Golden Mosque).[1][2] The mosque is one of the best-preserved sultana monuments under protection by the Department of Archaeology and Museums, Governments of Bangladesh. The gilding that gave the building its name does not exist anymore. The mosque premise, which covers an area of 42 m from east to west by 43.5 m from north to south, was originally surrounded by an outer wall (now restored) with a gateway in the middle of the east side.

The interior of the mosque, measuring 21.2 by 12.2 m is divided into three aisles by two rows of stone pillars, four in each row. A wide central nave has cut the aisles into halves, each half showing six equal square units with a side of 3.5 m. The nave has three rectangular units, each measuring 3.5 by 4.5 m. The interior of the mosque has therefore a total of fifteen units, of which the three rectangular units are covered with chauchala vaults, and the remaining twelve square units each by an inverted tumbler-shaped dome. They are all carried on radiating arches springing from the free-standing stone pillars and the engaged pilasters. The upper corners in between the arches of the square units are filled with corbelled brick pendentive to make up the phase of transition for the domes. At the northwest corner of the mosque there is a royal gallery forming an upper floor, which is still standing in a dilapidated condition. It was approached from the northwest corner of the mosque through a stepped platform connected with a doorway. The gallery has a mihrab in front.
Stone carving, brick-setting, terracotta, gilding and glazed tiles were used in decorating the building, and of them the former played the dominant role. The subject matters of the stone carving were chosen according to the demand of the spaces, e.g., the borders of the panels with creepers and their interior with various forms of stylised hanging patterns adapted from the chain-and-bell of the Bauddha and Jaina period. The spandrels of arches and the spaces above the frames are always dotted with rosettes, an attractive form of designs, but are all carved differently. The interior of the domes and vaults are decorated with terracottas, those of the vaults being copies of the bamboo frames of local huts. All the frontal archways and those of the mihrabs are cusped.

The glamour of the Chhoto Sona Masjid is not there as it was originally, particularly because of the stripping of the decorative mihrabs and the mosque courtyard, but the remains are nevertheless one of the most attractive monuments of Guar-Lakhnauti.
