The Our Lady of the Immaculate Conception Cathedral is the episcopal seat of the territorial prelate, in Basco, Batanes.

On 6 February 2002 renamed Territorial Prelature of Batanes / Batanen(sis) (Latin adjective).

The silver crescent symbolizes the Immaculate Conception, the titular of the principal church in the prelature.

The North Star together with the constellation of the Ursa Major denotes that the prelature covers the northern-most part of the Philippines.

Cattle is the most important export product of Batanes and Babuyan Islands hence the bull on pasture.
