Patan Devi, also called Maa Patneshwari, is the oldest and one of the most sacred temples of Patna. It is regarded as one of the 51 Siddha Shakti Pithas in India. According to Puranic legends, the 'right thigh' of the corpse of Devi Sati had fallen here when it was chopped off by Lord Vishnu with his 'Sudarshan Chakra'. The ancient temple, originally called Maa Sarvanand Kari Patneshwari, is believed to be the abode of the goddess Durga.
