Triplicane has the city’s oldest mosque

The mosque has a large prayer hall, a tank and a large ground in front. The entire structure is constructed with granite without the use of iron or wood. Big Mosque is the largest mosque located in the city from the time of its establishment. 

There is no fixed architectural style, though the two minarets are characteristic of Mughal architecture. Historians attribute the change of architecture to the arrival of North Indian Muslims who settled there. A chronogram written in Persian by Raja Makhhan Lal Bahdur Khirat, the Hindu Munshi of the Nawab, is found at the entrance to the prayer hall.
