Each year, during the second week of October, the St. Mary's Forane Church in Thrissur district becomes the vibrant center of celebration for the Koratty Muthy's Feast. Dedicated to the Virgin Mary, locally revered as Koratty Muthy, this grand festival is steeped in tradition and marked by colorful pageantry and rituals. The event attracts a large number of devotees, drawn by its rustic charm and deep spiritual significance.

Koratty, the picturesque village where the festival is held, transforms into a lively hub of devotion and festivity. The Koratty Muthy's Feast is distinguished by its unique traditions and community participation. One of the most notable aspects of the festival is the main offering, known as Poovankula, which is a variety of plantain. The Thulabharam ritual, where devotees offer their body weight in plantains as a symbol of total surrender to Koratty Muthy, is a highlight of the event. This act of devotion, where believers weigh themselves against offerings of Poovan bananas, underscores the deep faith and dedication of the participants.

The feast, often referred to as the celebration of Our Lady with the Poovan Bananas (Poovankula Matha), not only serves as a religious observance but also as a cultural gathering that strengthens the bonds of the community. The festival is a blend of spiritual fervor and cultural richness, offering a unique glimpse into the religious life of Kerala.

The Koratty Muthy's Feast at St. Mary's Forane Church is a testament to the enduring faith and traditions of the people of Thrissur. It is an event that beautifully encapsulates the spirit of devotion, community, and cultural heritage, making it a must-visit for those seeking to experience the vibrant tapestry of Kerala's religious festivals.
