Valluvar Kottam
Opened in 1976, this massive auditorium was constructed in memory of the poet-saint Thiruvalluvar. All 1,330 verses of his epic work, "The Thirukkural", are inscribed on the surrounding granite pillars. The central feature is a 30m-high (100ft) sculpture of a chariot, inspired by ancient Dravidian temples like the Sun Temple at Konark. There is a life-size image of the poet inside.
