The aim of this article is to highlight the educational contribution of Bishop Peter Remigius in Kottar diocese and Kumbakonam diocese. One of the primary Catholic churches in South India is St. Xavier's Church in Kottar. Devasahayam's mortal remains were interred in the St. Francis Xavier Church, which was later transformed in 1930 into the Cathedral of the Diocese of Kottar. The Kottar Diocese held a significant position for Christianity, particularly Roman Catholicism. The diocese of Kottar was established on October 5, 1930. New Kottar Bishop Rev. Lawrence Pereira was installed in office. Between 2007 and 2017, Bishop Peter Remigius, who is the fifth Bishop of Kottar, was installed. Prior to that, from 1990 to 2007, he served as the bishop of Kumbakonam. On June 30, 2007, he was transferred to Kottar.1
