Murugan Devadanam is an east-facing temple built in a differing architectural style from other temples. The entrance is through a tall Mukha Mandapam with four pillars that resemble small mandapams in the facade. This is followed by a huge and long Mani Mandapam with a domed structure with the temple bell in it. This is followed by another long corridor with pillars that goes inside the Prakaram where the sanctum sanctorum of Lord Muruga is present. The shrines for Vinayaka and Idumban are also in this prakaram. A couple of kilometers behind this temple is an ancient Shiva Temple and a small Muruga Temple on a hill on the way.
