History
The Diocese
of Thanjavur covers the entire area of the District of Thanjavur
and the newly formed districts of Nagapattinam and Tiruvarur
(with the exception of two Taluks, namely Kumbakonam and Papanasam).
The diocese also covers seven Taluks of Pudukkottai and one
Taluk of South Arcot district.
The Diocese
of Thanjavur originally forming part of the southern portion
of the ancient Dioceses of Mylapore, was separated from Mylapore
and erected into a Diocese on November 23, 1952 by the Holy
See by the Bull of erection "Exprimaevae Ecclesiae".
The town of Thanjavur was made the Episcopal See and the Sacred
Heart Church, Thanjavur, the Cathedral.
The Diocese
of Thanjavur is bounded on the east by the Bay of Bengal, on
the west by the boundaries of Trichy and South Arcot districts,
on the north by the river Vellar and on the south by Ramnad
district.
The territory
constituting the present Diocese of Thanjavur, had been the
fruitful field of heroic labours of Portuguese Padroado Fathers
from Goa and other Fathers such as the Franciscans, the Jesuits,
the Foreign Missionary Society of Paris, the Salesians and members
of the Diocesan Clergy.
Bp R. A.
Sundaram was appointed the First Bishop of Thanjavur.
