The temple is 400 feet above sea level on a hill.  There are 496 steps to reach the temple.  It has mentions in the 10^th and 12^th century records it is said.  The whole hill temple is built with stone comprising a Rajagopuram, Deepasthambam, flag post,, front Mandap, prakara, sanctum sanctorum for the presiding deity and is under the control of the Hindu Religious and Charities department.  Lord Vinayaka has His place between two trees Arasu and Vembu before Rajagopura Mandap and Deepa Stamba.  There are also shrines in the space for Lord Kailasanathar-Mother Gnanambika; Deepasthamba; Kannimoola Ganapathi, Dandapani,flag post and Balipeeta.  Sumookar and Sudhekar are Dwarapalakas.   There also 8 Shakti shrines – Ashta Durgas, Aalambadi Vana Sakshi (Kattammai), Pappini Angala Prameswari, Kangeyam Ayee Amman, Valuppuramman, Thangamman, Andhanuramman, Karia Kali Amman and Selvanayaki Amman.

The 18^th step to the hill is called Sathya Padi where cases between two litigants were tried and settled in the past.  Padi means step.  This is also called Purana Padi.  It is believed that Sadaichi Amman is residing on this step to watch the trials and justice rendered.   An Artha-Meru-a Yantra is also installed here with the footsteps of Mother Valli Amman.

Devotees seek from Lord Subramania boons for wedding, for a child, progress in business, relief from diseases etc. and they do get the response for their prayers.  Circumambulating the Navagra shrine 9 times promises solution to all the problems of the devotee.  Sani Bagwan has his own shrine separately. 

A devotee of Lord had learnt that there are seven springs – Hanuma Theertham, Agasthya Theertham, Indira  Theertham, Mangala Theertham, Veera Theertham, Shakthi Theertham and Brahmmananda Theertham and also the glory of Ganga.  She sought the permission of Lord Muruga.  It is believed hat Lord Muruga showed her Kasi (now Varanasi) and the Ganga, creating them here itself.  It is noteworthy that the Kasi Ganga theertha exists in the Nandavanam-garden, part of this hill.  It is also believed that Lord Vinayaka, though elder worships Lord Muruga in this hill.  The first Puja is offered to Lord Muruga only against the general principle of dedicating it to Lord Vinayaka in our temples.  Lord Muruga is also praised as Annadhana Murthy and Valli Manalan.

Valli performed penance in this hill to get Lord Muruga, established charity halls known as Valli Arachalai.  The place is now Valliarachalai.  The glory of the hill is that the herbal plants and air on the way to the hill cures many prolonged diseases. People believe that there are still Siddhas living in the hills though they are not visible.

There is a box in the temple known as Andavar Utharavu Petti – box containing the directions of Lord and the action people have to take.  He also gives the reasons – Karanam in Tamil, hence He is praised as Karana Murthy.  Such instructions are given to the devotees in their dreams.  Before placing them in the Utharavu Petti, they seek the permission from the priest through some fruit or flower.  When they placed a gun, Chinese war took place, electric motors reduced the use of ropes for drawing water from the well brought tsunami, turmeric, gold, sand, mud caused hike in the prices of these commodities and real estate values.  Something good or bad occurs from the articles placed in the Utharavu petti.
