Kottiyoor comes from Koodi(Meeting) and Uuru(Precinct); the name comes from the pilgrimage in the region. The mythology says that this is the place where the holy trinity (Brahma, Vishnu and Shiva), Veerabhadra, Bhadrakali, Shiva Bhutaganas, revered Sages and other holy men came together to complete the Daksha Yaga. It is believed that Sati Devi immolated herself here.
