This temple is built at the western most end of the Vilwamala. High granite walls have been erected in the north, west and south sides of the temple. The pathway inside the compound wall, which is used by the devotees to circumambulate the deities, has been completely paved with granite slabs. Long flights of granite steps are seen at the south, west and north sides of the temple. The granite steps in the north take us down to the "Bhagavathichira".

On the eastern side an 'Agrasala' is seen stretching out from north to south. This is supposed to have been constructed by the kings of Palakkad, known as "Edathil Achanmar", using clay brought from their own place. Even though these kings were not entitled to enter the temple, they used to erect a temporary shed on one side of the temple and conduct a feast in connection with the famous 'Ekadesi' celebration, purely as their offering to Vilwadrinatha. The basement of the "Kizhakke (East) Gopuram" can be seen very close to the "Agrasala". There is the compound wall in the remaining part. The temple of Hanuman faces the west and is quite adjacent to the "Kizhakke Gopuram" inside the compound wall. The store-house of the temple and a stage for the performance of various entertainments connected with the temple festivals have been built very close tothetemple of Hanuman. Inside the compound wall and "Pradakshinavazhi" is the "Vilakkumadathara" on which nine rows of oil lamps are fitted. On festival days it is a spectcular sight even from a distance when the temple is illuminated with all the nine rows of oil lamps lit on all the four sides. A courtyard is seen all round inside the "Vilakkumadathara". Beyond this courtyard are the "Chuttambalam" (Buildings around the sanctum sanctorum of the temple). We can go inside the temple through the "Panjanam" (as it is called), on the eastern side of the temple. The self built "Balikkallu" is seen here. We reach the Kizhakkambalam when we pass the "Arathotti" near the Balikkallu. The "Thidappilly" where rice and other articles for pooja are prepared, and the mess hall are on its western side. Next to that is the "Padinjarambalam". Here the building in which the Balikkallu exists is near the western entrance of the temple just opposite to the western shrine. This entrance has "Vathilmadam" on the north. Next to that is "Eeduveppu", the "Dark room" and "Vadakke kettu". The "Chuttambalam" which encloses these structures surround the sanctum sanctorum of both the shrines. One has to cross the compound wall, Vilakkumadathara and Chuttambalam in order to reach the sacred inner Qourtyard of the temple. There are two seperate shrines here, one facing the east and other facing the west. Both contain the idol of Vishnu with four arms. The eastern shrine accommodates the idol installed by Parasurama while the western shrine is blessed with the self-built idol of Vishnu as He appeared before Rishi Amalaka. In the west the idol is seen under the hoods of serpant Anantha attended by Goddess Lakshmi and Goddess Earth on either side.

The shrine of Mahaganapathi can be seen facing the east in the southwest corner of the inner courtyard. The entire grand architecture has been set in a divinely magnificent background. While the peepul trees in the west seem to be immersed in chanting prayer hymns in a rhythemic style, the peepul tree in the east with its roots firm in the rock seems to meditate with the name of Ram on its lips. Hills with green trees can be seen all around the temple.

The Bharathapuzha clappping her hands at the sound of the roaring trains, the gentle breeze providing health and longevity and the beautiful green forest around make the temple and its premises serene, divine and blissful.
