Neelamperoor Patayani is a spectacular event that takes place at the Neelamperoor Palli Bhagavathy temple in the district of Alappuzha. Though Patayani is performed in a number of other temples in Kerala, the one held at Neelamperoor is entirely different from others. It comes in the Malayalam month of Chingam (August / September). The word patayani literally means row of warriors. The event is a riot of colours, fervent devotion and festivity.
Massive effigies of swans and other legendary characters are brought in procession. The making of the effigies of the swans is locally known as annamkettu.
