The diocese of Kottapuram belongs to the Latin Rite. The Roman Catholic diocese of Kottapuram is the suffragan of the archdiocese of Verapoly. The diocese of Kottapuram was established by Pope John Paul II by the papal bull "Quo Aptius" on July 3, 1987 from the Metropolitan archdiocese of Verapoly. The diocese of Kottapuram was officially inaugurated on Oct. 4, 1987. Bishop Francis Kallarakal is the first bishop of the new diocese.
This diocese is located in the city of Kottapuram in the ecclesiastical province of Verapoly archdiocese which is spread across the civil districts of Ernakulum, Thrissur, Malappuram and Palakkad districts of Kerala and covers an area of 3,000 square kilometers. The diocese is headquartered at Kottapuram, near the ancient city of Cranganore (the anglicized name of Kodungallur). The word Kottapuram means 'the place around a fort'. This place owes it name to a fort constructed by the Portuguese in 1503. Kodungallur/Cranganore was a famous seaport of the East since ancient times. To the Greeks and Romans Cranganore was known as Muziris. It was one of the thriving earliest Christian settlements of Malabar.
According to tradition, St. Thomas the apostle landed and preached the gospel here in the year 52. He established a Church which is believed to be the first Christian Church in India. Since then it was a prominent Christian centre. The existence of a thriving Christian community attracted the attention of the bishops from Persia who chose this place as the centre of their activities. By the middle of 14th century, the fame of the seaport fades into oblivion. Today Kottapuram is a part of the Thrissur district of Kerala and at the southernmost border of the Kodungallur municipality.
