The temple was very popular in the second Chera dynasty. After the fall of the Cheras, the place came under several rulers, the Thekkumkur and Travancore kings were prominent, witnessed many brutal wars, treachery, murder and annihilation. However, in all these cases, the temple was saved from destruction by the will of God and the prayers of the devotees. The legend behind this concept is that Chera king Palli Bana Perumal, when de-throwned by the Bhattas (learned Brahmins) following a defeat in argument, traveled to Neelamperoor. The news came to the ears of the Potti Leaders of the Pathu Illams (Chengazhi Muttam, Kainikkara, Eravi Mangalam, Kunnithidasserry, Athrasserry, Kolencherry, Kizhangazhuthu, Kannancherry, Thalavana etc.), that the king is going to install his own personal idol at Neelamperoor.
In the time of Pallibana perumal, it was decided to convert the Neelamperoor Shiva Temple into a Buddhist monastery. It is believed that the ten Brahmin families (later known as Pattiyillam Pottimar) came to Vazhappally by shaking the Shiva Linga of the temple of Neelamperoor and then merged with the existing shiva temple in Vazhappally. The Shiva lingam brought from Neelamperoor was first placed in the Devalokam at north part of Vazhappally gramam.[6] Later, when they tried to shake the Shiva Linga but was unable to do so, Parasurama appeared to the grieving Brahmin family and offered him the Shiva Linga he had worshiped and advised him to build the temple on the Ardhanariswara concept. He built a huge shrine for the Shiva Linga and the Parvati idol.
The sanctum sanctorum was built inside the three walls of the rounded stone granite shrine to the east of the Shiva Linga and to the west the Parvathi idol. Dakshinamoorthy and Ganapathi were placed inside the sanctum sanctorum as a vision south. In the south-eastern corner of the Nambalam, there was a large Tidapalli built. Raja built the subshrine temple for Sastha at the Kannimoola outside the Nambalam temple. He was promoted to the position of temple tantric rites to the Taranalloor series and the Tulu Brahmin family of Kasaragod for priests for daily pooja. The main priest was appointed as an umbrella and provided accommodation in the Kuthasanthi Math.
