This locally known noy gombuj
mosque belongs to the credential of great builder
Khan Jahan Ali and was built in the middle of the
15th century. This is the finest example of a multi domed square shaped plan situated at the western side
of the big Thakur Dighi near Khan Jahan Ali tomb at
Bagerhat. Existence of a ruined ghat, which has a strong
axial relationship with this mosque, is still visible. Khan Jahan Ali introduced an unconventional design of
mosque "square-shaped", which is a typical form of a
Muslim mausoleum or central shrine of a Buddhist
temple ora garbagriha of a Hindu temple. This type of multi-domed square-shaped
mosque is uncommon and rare in the Islamic world.
However, this is one of the 3 surviving nine-domed
mosques in Bengal. The 17 meter square wide prayer
hall, surrounded by a 2.6 meter thick wall, is divided by
3 equal aisles and bays. It is roofed with 9 low
hemispherical domes. It has 3 arched entrances to its
east, north and south sides, bordered within tall
rectangular bands of terracotta ornamentation. The
band or panel is decorated with geometrical pattern of
ornamentation, which is to some extent abstracted or
simplified form of natural floral form. Corresponding to
each aisle is a mihrab niche in the kibIa wall, which is
placed directly opposite to the entrances in the eastern
wall; among them the central one is wider and higher
than the flanking ones. A chain and bell terracotta
motif decorates the apsidal centre of each mihrab; a
large terracotta rosette is placed above the apex.
Besides, there are four small niches in northern and
southern wall, which were used as place of oil lamp.
This mosque has only 4 circular corner turrets, one at
each corner of the building.There are four freestanding black basalt pillars in the
hall. The pilasters are made of brick, but capital of the
pilaster is made of stone. These types of construction
with small pieces are observed in all monuments in
Bagerhat. The source of stone for Bengal was mainly
Rajmahal hill of Bihar, which is very far from Bagerhat.
So the builders of Bagerhat imported small sized stones
to avoid breakage and for easy transportation.
