Exit through the main gate of the Sangam, turn left and follow the small road in the direction of Kolivakkam. After about 100 meters you will see an amazing monument situated at the cross-roads of 3 villages: Kolivakkam, Punjarasantankal and Aiyankarkulam. This unique underground mandapam (pillared hall) is open once a year during full moon in the month of Chittirai (April-May) when the water is pumped out of the well. People from nearby and far visit the well and so does the God Varadaraja Perumal (Vishnu). As part of a larger procession, he spends the night there — with his consort Bhuma Devi.

Head out through the back gate of the Sangam’s farm towards the sloping bank. After a steep climb you will be rewarded with a magnificent view of a temple dedicated to Hanuman, the monkey-god and devotee of Lord Rama, and the huge water reservoir that has been constructed in front of the temple.

Upon entering Aiyankarkulam, the village next to the Hanuman temple, you will hear the sound of hand looms. Here silk is woven at home by traditional weavers.
