Chennai stacks 1,300 years of history in layers: Pallava-era shrines at Mahabalipuram, Portuguese and Armenian traders in George Town, and the fort where Britain's Indian empire began in 1644. Walk them in sequence and the city's whole story unfolds.
Chennai's oldest structure, founded by the Pallavas in the 8th century and expanded by Cholas and Vijayanagara kings. The only temple showing five Vishnu avatars; inscriptions in Pallava-Grantha script survive on the inner walls. Open 06:00–12:00, 16:00–21:00.
The world's finest collection of Chola bronzes, including the 11th-century Ardhanarishvara and Nataraja figures cast by the lost-wax method. Housed in the 1851 Indo-Saracenic complex. Open 09:30–17:00, closed Fridays.
One of only three churches worldwide built over an apostle's tomb. The Portuguese raised the first church here in 1523; the neo-Gothic building dates to 1896. The underground crypt holds the burial chamber and a 16th-century Portuguese stone cross.
The 300-foot hill where the apostle Thomas is said to have been martyred in 72 CE. The 1523 Portuguese chapel at the summit holds the Bleeding Cross, carved from stone, and a painting of the Madonna attributed to St Luke. 134 granite steps lead up.
Britain's first Indian fortress, completed 1644, now housing 10 galleries of Company-era weapons, palanquins, coins and the original Union Jack lowered in 1947. The 1795 Exchange Building holds Clive's letters and Cornwallis's marble statue.
Built 1712 on Armenian Street by merchants who ran Chennai's Persian trade. Six bells cast in 1754 still hang in the belfry, the largest in the city. The courtyard holds 350 Armenian gravestones, the oldest dated 1663.
Robert Chisholm's 1879 masterpiece of Indo-Saracenic architecture, mixing Byzantine domes with Chalukyan detail. The 150-foot hall hosted every Madras convocation for a century and was restored in 2006 after decades of neglect.
The 1913 neo-Baroque Ripon Building, seat of the Chennai Corporation — Asia's oldest municipal body, founded 1688 — stands opposite the 1888 Victoria Public Hall, where the first Indian National Congress delegates from Madras met.
The Pallava port capital 55km south, carved 630–728 CE under Narasimhavarman I. The granite Shore Temple and five monolithic rathas cut from single boulders are UNESCO-listed. Arjuna's Penance is the world's largest bas-relief at 27m by 9m.
Eighteen relocated heritage houses from across South India, dismantled and rebuilt beam by beam — a Chettinad merchant mansion, a Tamil agraharam street, a Kerala Syrian Christian home. Open 10:00–18:00, closed Tuesdays.
The 'Black Town' laid out beyond the fort walls in 1673, where Tamil, Telugu, Armenian, Jewish and Gujarati traders lived in separate quarters. Wholesale bazaars still occupy Godown Street and the 1795 High Court complex anchors the south end.
Headquarters of the Dravidar Kazhagam, holding E V Ramasamy 'Periyar's' library, his samadhi and the archive of the 1925 Self-Respect Movement that broke caste and Brahmin ritual dominance and reshaped Tamil politics for a century.
