The Brihadeeswarar temple (Tamil: பெருவுடையார் கோவில்; Peruvudaiyar Koil) is an ancient Hindu temple located at Thanjavur in the state of Tamil Nadu, India. The temple is dedicated to Shiva and dates to the Chola dynasty rule in the 11th century CE.
The temple is part of the UNESCO World Heritage Site "Great Living Chola Temples". This temple is one of India's most prized architectural sites. It depicts the amazing and outstanding efforts of the ancient Indians. The building that carries the main sanctum is known as the 'Periya Kovil'. This stands amidst fortified walls that were probably added in the 16th century. The 'Vimana' of the temple is about 70 meters and is among the tallest of its kind in the world. The 'Shikharam' (crown) of Brihadeswara temple is itself very large and heavy (81.25 tons) and has been carved out of a single stone.
