The east facing temple has a long compound wall on all sides with aesthetic workmanship with a beautiful entrance.  There are front and Maha and Artha Mandapas and the sanctum sanctorum.  Nandhi the bull vehicle of Lord Shiva and the Balipeeta adore the mandaps.  Lord Chozheeswar blesses the devotees in His Linga form facing east from the sanctum sanctorum.  Lords Dakshinamuthy, Brahmma, Vishnu and Chandikeswara are around the sanctum in their respective shrines.  Mother Soundarya Nayaki graces the devotees from Her own shrine.  In between the Lord and Mother’s shrines appears Lord Muruga with His consorts Valli and Deivanai.  There are also shrines for Lord Vinayaka, Kasi Viswanatha, Nataraja, Kala Bhairava and Mothers Durga Matha, Kasi Visalakshi, Sivakamasundari.  Planets Sani Bhagwan, Moon, Sun and the Navagrahas are in their separate shrines.  There is also a neem and Arasu tree embracing each other.     Lord Vinayaka, Nagar and Nandhi are under this tree.

Devotees take part in the pujas dedicated to Lord Kala Bhairava on Ashtami days (8^th day of new moon or full moon fortnights) and in the pujas for planets Rahu and Ketu on Tuesdays for relief from the adverse impact of these planets and for relief from various worries they face and for child boon.

There is a 60 feet tall lighting post – Deepasthamba – before the temple praised as Kambathu Andavar meaning lord of the pole.  Lord Muruga adores the post.  It is also adored with Sri Anjaneya on one side and an elephant on the other.  Guruwar – Thursday – abishek is offered to Lord Dakshinamurthy.  People participate in the pujas for Nardana Ganapathy, Pasupatheeswarar and Mother Soundarya Nayaki to achieve excellence in education.  During the pujas on Thursdays and Sundays a  herbal root is placed at the feet of Lord Chozheeswarar and offered to those affected by poisonous bites and by jaundice.  They wear it as a garland with diet restrictions for three days for total relief.  Many confirm this with their personal experience.

Moolanur is a fertile region with agriculture as occupation of the residents here.  A sage by name Moolan lived here about 1,200 years ago and the place is named after him as Moolan Nagar and Moolan Maanagar and finally Moolanur came to stay.  Moolan had an ambitious plan to build a temple for Lord Shiva.  Lord Chozheeswarar temple came into being with the help of the chieftain of the place Poosa Kula Thondaiman.  Chera and Chola kings had done renovations later.  The temple is praised by Saint Sundarar in his Thevaram hymns.  He worshipped Lord Shiva while on his way to Palani, according to local history.
