Erumbeeswarar Temple in Thiruverumbur, Tamil Nadu, India, is a Hindu temple dedicated to the deity Shiva. Built on a 60-foot tall hill, it is accessible via a flight of steps. The temple's main shrines and its two prakarams are on top of the hill, while a hall and the temple tank are located at the foothills. Shiva is believed to have transformed himself into an ant hill and tilted his head at this place to enable ants to climb up and worship him. The temple is one in a series built by Aditya Chola 871-907 CE along the banks of river Cauvery, to commemorate his victory in the Tirupurambiyam Battle. It has several inscriptions from the Chola Empire dating back to the 10th century. The temple has been declared a protected monument by the Archaeological Survey of India.
