Thiruverkaadu is situated about 20 kms from Chennai city. It lies on the road branching out off Mount Poondhamalli Road near Kumananchaavadi.Apart from an ancient temple for Lord Shiva called as Sri Vedhapureeswarar temple, Thiruverkaadu also has a temple for Sri Karumaari Amman, which is more popular in Chennai.
According to the legend, once Sri Karumaari Amman took form of a fortune teller and went to Sun God for predicting his future. Sri Surya Bhagawan neglected Her and Sri Ambaal vanished from his sight, because of which Sun God lost his powers and glory. Then Surya Bhagawan realized that it was none other than the Goddess Herself and came and worshipped her here at Thiruverkaadu, seeking apologies. Goddess pardoned him with mercy and Sri Surya Bhagawan requested her to bless that Sunday (Sun God’s day) be the auspicious day for the Devi here. Goddess obliged to it. Also the Sun God spread His rays on the Goddess here during the Thamizh months Panguni and Purattaasi to show His devotion to the Goddess.
In ancient days, this place was a forest filled with VeLvela trees (வெள்வேல மரம்) and hence was called as Velankaadu (வேலங்காடு), which later turned to get its present name. It is also said that Lord Muruga, before His battle with the demon king Surapadhman, got His weapon ‘Vel’ (வேல்) from Sri Karumaari Amman here and so the place was called as Velankaadu.
It is said that Sri Vinayagar (Lord Ganesha) worshipped the Goddess here by performing Abhishegam using Valampuri Sanghu (Conch). The Goddess got pleased with His worship and blessed Him that the poojas at the temple will first be performed to Sri Vinayagar and then to Her. Sri Vinayagar can be seen present in the temple just as we enter the temple near the Dhwajasthambham. While entering the temple, one has to pray Him and then go further to worship Sri Karumaari Amman.Once, when the Asuras gave troubles to Devas, they came and worshipped Lord Shiva at Thiruverkaadu, to save them. Lord Shiva called His Devi Sri Verkanni and directed Her to look after His duties till He is back from Devaloka. Lord Shiva gave her the holy ashes from His body and blessed Her. The Goddess asked Sage Agasthiyar to look for a holy place where she can perform the heavenly duties assigned by Lord Shiva. When Sage Agasthiyar was thinking of such place, he heard an Asareeri (அசரீரி – a holy voice) saying that the place where he was standing itself is a holy place. Goddess took abode here as Sri Karumaari Amman and also blessed the place that one will be removed of all the sins by worshipping Her at Thiruverkaadu.

While people dug up the place, an axe like tool which was used to dig the ground hit on the Shiva Lingam and created a scar on Him. The axe like tool was called ‘Vaasi’ in Thamizh and hence the Lord here is called as Sri Vaaseeswarar.
