This ancient temple is at Thachonam Anchumalakunnu in Kollam district. It is more than 1500 years old. As the place is surrounded by five mountains it is known as Anchumala Kunnu Aayiravilli kavu. A place blessed by nature with hills, mountains, dew and forests, it is seen as the best place to consecrate all the gods. In the astrological consultation held at this temple, it was seen as the place where the 33 crore gods visit. Lord Siva and Goddess Parvathy are present in this temple throughout the time. So, nobody enters the compound at noon or midnight.  As it is not possible to consecrate more 33 crore gods, it is seen as the Aayiravilli.
