The highlight of Machattu Mamangam is the grand ceremonial procession featuring Kuthirakolams—large, beautifully crafted and vividly decorated effigies of horses. These horse effigies are created by the local communities using bamboo, cloth, and paper, often reaching heights of several meters. They are not ridden but are carried on shoulders by groups of men in a vibrant and rhythmic march toward the temple, accompanied by traditional percussion ensembles like chenda melam and panchavadyam.
Each Kuthirakolam represents the offering of a local village or group, and the process of crafting and parading them is both an artistic expression and a spiritual offering to the deity. The colorful spectacle, loud music, and festive atmosphere transform the temple grounds into a hub of celebration and devotion.
Though it has religious roots, Machattu Mamangam also serves as a major social and cultural event, fostering unity among the participating communities. People from various backgrounds gather to witness and take part in the festival, which includes not just the procession, but also traditional music, dance, and other folk performances.
The festival culminates on the final day with the most elaborate procession, where all the Kuthirakolams converge at the temple, creating a stunning visual and spiritual climax. This convergence symbolizes the unity and collective devotion of the people toward Goddess Bhagavathy, making Machattu Mamangam a unique and unforgettable celebration of Kerala's rich cultural heritage.
