About this Place

Potharai Fort, also known as Athimoor Fort, is a captivating historical hill fort near Polur in Tamil Nadu. Dating back over 400 years to the Maratha rule of Rajaram Chatrapathi, the fort, though now largely in ruins, features extensive walls that once stretched for nearly 5 kilometers.

Its dilapidated state, with ancient walls overgrown by trees, adds to its rustic charm and historical mystique. Beyond its Maratha heritage, the surrounding area reveals evidence of a much older past, including 3000 year old Stone Age burials.

Perched on an 1800 feet high hill, the fort offers a challenging yet rewarding trek, culminating in panoramic views of the landscape. It remains an uncommercialized and offbeat destination, perfect for those seeking adventure, a deep dive into history, and a connection with ancient heritage.
