Champakulam Kalloorkadu St. Mary’s Basilica (also called Champakulam Valia Palli) is one of the oldest Christian churches in India and the mother church of almost all Catholic Syrian churches in Alleppey District. Believed to be established in AD 427,the church was
rebuilt many times. Champakulam church was once under Niranam Church, which was founded by the Apostle Saint Thomas himself.
The many rock inscriptions found around the church tell us about the history of the church.

The open air Rock Cross at Champakulam church is one of the most ancient crosses with clear documentation of its antiquity, dating to AD 1151. There are many archaeological artifacts found around the church that tell more about its history. Champakulam Church had very friendly relations with the Puthenkoottukar and had a pivotal role in many ecumenical efforts in the eighteenth century. Ikkako Kathanar, one of the martyrs (nasranis) of East Syriac Catholics, was born in this parish.
Champakulam church has been recognized by the Universal Church as a Basilica. On 27 November 2016, the church was officially declared as a basilica by Pope Francis and Mar Joseph Perumthottam, the Metropolitan Archbishop of Changanacherry. This is the first basilica in the archdiocese of Changanasserry, the fourth in the Syro Malabar Church, the ninth in Kerala and the twenty-third basilica in India.
