Navagraha Temple, Guwahati
In the eastern part of Guwahati located on the Chitranchal hill is the Navagraha temple, an ancient seat of astrology and astronomy. It is referred to as the temple of the nine planets and is believed to have existed since Puranic times with the present structure built by Rajeswar Singha, an Ahom king. Housed in a red beehive-shaped dome is a central lingam (stone phallus), which is encircled by nine representations of the planets. There is also an imprint of the solar system inside the temple.
This temple is one of the reasons Guwahati was referred to as Pragjyotishpura or city of eastern astronomy.
