The Assumpta Cathedral [1] also called Owerri Cathedral Is the name given to a religious building belonging to the Catholic Church which is located in the city of Owerri,[citation needed] the capital of the state of Imo in the southeastern part of the African country of Nigeria.

The temple follows the Roman or Latin rite and is the main church of the Metropolitan Archdiocese of Owerri (Archidioecesis Overriensis) which began as an apostolic vicariate in 1948 and obtained its current status in 1994 through the bull "Ad aptius efficaciusque" by then Pope John Paul II.

[3] The plan to build a modern cathedral in Owerri was led by the diocese and its Irish Bishop, Joseph Brendan Whelan.

Before the war, construction had progressed and the main part of the building with the exception of the roof deck and covering was already finished.

[4] During the war, the site of the cathedral came under fire a few times because the dome was thought to be an observation post.
