• December 21, 1985: Established as Diocese of Punalur from the Diocese of Quilon

Belgian Carmelite missionaries were the First Fathers of Punalur and of places around Punalur. During the Second World War the First Fathers had to go back, entrusting the church work to the diocesan clergy of Quilon (Kollam).

Punalur was separated from the Diocese of Quilon (Kollam) and created into a separate unit by the Bull “Verba Christi” of Pope John Paul II, issued on 21 December 1985.

Present Diocese of Punalur extended to the entire taluks of Punalur, Pathanapuram, Kottarakkara, Kunnathur, Mavelikara, Adoor, Konni, Pathanamthitta, Kozhencherry, and several pakuthies of the taluks of Karunagappally, Karthikapally, and Chengannur.
