Jama Mosque: The Jama Masjid is a mosque in the Kalbadevi neighborhood, near Crawford Market in the South Mumbai region of Mumbai, India. The date of its completion (AD 1802)/(AH 1217) is derivable from the chronogram Jahas-i- Akhirat, “The ship of the world to come” which contains an allusion to the fact that it was constructed on the tank . In the eighteenth century, this tank was situated in the midst of gardens and open land and belonged to a Konkani Muslim merchant trading in Goa, and Calicut, who, about 1778, agreed to the erection of a mosque on the spot, provided the tank was preserved intact. A one-story building was therefore erected over the tank and formed the original nucleus of the present Jama Mosque. The Jama Mosque is a quadrangular pile of brick and stone, encircled by a ring of terrace roofed and double storeyed buildings, the ground floors of which are let out as shops. The chief or eastern gate of the mosque leads directly across an open courtyard to the ancient tank, which is now furnished with masonry steps and embankments, built in 1893, and contain about ten feet of stagnant water, filled with gold and silver fish. From the depth of the tank rise sixteen black stone arches, constructed in 1874, which support the whole fabric of the mosque, the upper story being upheld by five rows of wooden pillars, each of which contains a receptacle for sacred books. The arches in the tank were built in 1874 at a cost of Rs. 75000/- while other noteworthy additions to the premises are the large windows in the north, east, and south sides constructed in 1898, and the school building Rs. 20000 in 1902.
