This ancient temple is at Marayamuttam, Thiruvananthapuram. According to legends, there was a very devout elder of the Kuzhithalam Nair family at the place known today as Marayamuttam. One day, as he was bathing in the Chittar River, he got two tender arecanuts. When he reached home, he kept them on the shelf. After dinner, he took the arecanuts and started cutting them to be used with betel leaves. Blood started oozing out of them. That night, he had a vision of the calm Neelakeshini Devi and the fierce Sree Bhadrakali. They informed him that they had come to him in the arecanuts and instructed more him to make idols and consecrate them for worship. After astrological consultations, two idols were carved from the trunk of the jackfruit tree growing in his compound. A temple was constructed after clearing some forest land, and the two idols were consecrated there. The two idols are extremely beautiful, with the very rare Nagakettu. Each Naga has been made separately and strung together. There are many intricate carvings done on the idols. They are like the figures of the Goddesses as they appeared before the elder member of the family. Both idols are in the same sanctum, which is a practice that is rarely seen. The gentle Neelakeshi faces the east while the fierce Bhadrakali faces the north. Ganapathy, Matan Thampuran and Nagas are consecrated as subordinate deities.
