Cathedral of the Lord's Ascension, Bacău

The Church of the Ascension of the Lord is a church in Bacău, Romania and is the third largest cathedral in the country, after the People's Salvation Cathedral of Bucharest and the Holy Trinity Cathedral of Baia Mare.

Officially the structure is a church and not a cathedral, because Bacău is not the seat of any bishop. However, due to its size and importance, it is called by the locals "cathedral" – in the sense used in the primary Christianity, that of the main place of the city. Officially if the bishop will serve in this church, it will be cathedral or co-cathedral.
