As far as temples go, the Marundeeswarar Temple in Thiruvanmaiyur is the oldest temple in Chennai and is said to be built around 50 BC! The temple was built to honour Lord Shiva and is so old that you can find inscriptions of it on the much younger but more famous Kapaleeshwarar Temple in Mylapore. Do note that if you’re visiting the temple, that it’s best to go during weekday evenings as weekends are super crowded.
