The Collectorate of
Tiruchirapalli is located on a heritage building which was built during the 19th century. The building overlooking the Kuzhumai Amman Temple is located on the right bank of Uyyakondan River, one of the main tributaries of
Cauvery River.
The building is a blend of British and Nayak architecture. The ground floor and the first floor are octagonal in shape and the first floor once accommodated the collector's chamber. To the south of the building was the stable for the collector’s horses. The stable was demolished and the main building of the present day Collectorate is located here.
