Vadapalani Andavar Temple was built about 125 years ago, this much-hallowed and regularly frequented Lord Muruga sannidhi has emerged from a thatched shed, an unostentatious one enshrining a Murugan picture only, and established for itself a name on par with ancient places of worship. Around 7,000 couples are married here each year.
According to the sthalapurana, one Muruga devotee by name Annaswami Nayakar with his limited means built a small thatched hut and kept a Murugan painting for his personal worship primarily. During his meditation and worship, he used to experience some divine power entering his body and inspiring him to utter some mysterious things—whatever he said in his trance was found true. His utterance went by the name of 'arulvakku' ('God blessed statements') and relieved people in several ways, like curing diseases and getting jobs, solemnising marriages, etc.
There are very many sannidhis in the vast courtyards of the temple, like Varasiddhi Vinayaka, Chokkanāthar, Meenakshi Amman, Kāli, Bhairava, Shanmuga with Valli and Devasenā.
The moolavar in standing posture resembles the Palani Muruga in every respect. In the inner prakara, there are many niches housing Dakshina Murti, Chandikeswar, Mahalakshmi, et al. It has a spacious hall used for conducting marriages and religious discourses. It is one of the most-frequented Murugan shrines in the city of Chennai.
The entrance to this temple is crowned with a rajagopuram adorned with several stucco images depicting legends from the Skanda puranam. In front of the temple is the temple tank. The eastern tower rises to a height of 40.8 metres. The 108 bharata natyam dance gestures can be seen on the eastern tower as well
