The cathedral is the city's main Roman Catholic church, serving the Diocese of Comodoro Rivadavia, part of the Archdiocese of Bahía Blanca.
The building was constructed in Gothic-Modern style; some elements, such as a stained glass window, were brought from Turin, Italy, in 1959.
[2] As a result of the growth of Comodoro Rivadavia into a large city, a bishopric was established on February 11, 1957, by Pope Pius XII, encompassing the whole of Chubut Province.
The first bishop of Comodoro Rivadavia was Carlos Mariano Pérez, who took up office on July 6, 1957, remaining until December 26, 1963, when he was transferred to the Archdiocese of Salta.
[4] The cathedral, built in a constricted space in busy Avenida Rivadavia boulevard, has no garden area surrounding it and the paths are concreted.
