Dindigul is the headquarters of
Dindigul District. It is famous as a wholesale market for onion and groundnut.
The
Palani Hills begin just to the west of Dindigul. National Road 45 passes through Dindigul and connects the city with
Madurai, about 60 km to the south, and Tiruchchirappalli (Trichy) about 100 km northeast. It received its railway station in 1875 when the line between Trichy and
Tuticorin was constructed.
