Irinjalakuda is known for the Koodmannyamayam Temple and Thachootayai Kaiman. The Dravidian civilization, Jainism, and later Brahmanical rule prevailed. The movement against untouchability was formed under the leadership of Sree Narayana Guru, Ayyankali and his brother Ayyappan. The Iringalakuda town was declared a municipality by the Development Department notification dated February 8, 1936. Today it is difficult to distinguish between towns and cities. Irinjalakuda is land and coastal region where the topography and sand are the major factors. The eastern region can be categorized as hill, slope, and valley. There is another claim that the word "hen alkutai", which means 'big heel' in front of the temple, has evolved into a metamorphosis. In the inscription of the Kulasekharappumal Nasturanavirvamma, Irinjalakuda is referred to as Iringadikkudal and Devanu as Thiruvirungadi Thiruvadi. The new theory is that the grouping of the two temples means the irungkal kudal and it is the Irinjalakuda. Unnai Wariyar's works will include other legends of the Ramayana and Mahabharata, besides the story of Nalacharitam. Unnayavarivar's "Srirama Panchasati" is a beautiful hymn that can be described as a garland of praise for fifty decades, five hundred and thirty verses, addressed to Sri Sangamesan. Satchidananda, playback singer Jayachandran, film stars Innocent, Idavela Babu and lyricist KV Ramanathan are all contributing contributors to this land. The idol is a talisman of a statue, about four feet high, wearing a kodandam, an ashram, a wheel, and a shank. The Eritha Pooja, Udha Pooja, and Athazha Puja are performed. There is no festival offering, only Sribhutha sacrifice. Kudalmanikya Swamy is worshiped as a healer of devotees. It is believed that if you serve the Mukkudi Nidhava you will be cured for one year. The festival is celebrated for 11 days in the month of Thiruvonam. Once the flag is climbed, a small part of the Koodiyattam in Koothambalam marks the beginning of the festival. The other ten elephants are made of silver. .
