Diocese of Sisak

The Diocese of Sisak is a Latin Church diocese in the Sisak-Moslavina region, Croatia. It is a suffragan diocese in the ecclesiastical province of the metropolitan Archdiocese of Zagreb.
Its cathedral is Katedrala Uzvišenja sv. Križa, dedicated to Exaltation of the Holy Cross, in the episcopal see of Sisak, which also has a minor basilica: Bazilika Sv. Kvirina, dedicated to saint and martyr Quirinus of Sescia, the first bishop of the diocese.

History

Established in the 3rd century as Diocese of Siscia. Although Siscia became the capital of the Roman province of Pannonia Savia, it was not raised to Metropolitan status. Its history remains sketchy.
By the 7th century it may already have become extinct, its territory being taken over by the then Diocese of Zagreb, its future Metropolitan around the 10th century, the Sisak see being formally suppressed no later than the 11th century.
In May 1999, the diocese was nominally restored as Latin Episcopal titular bishopric of Sisak / Siscia / Siscien, but would only have a single incumbent, of the higher archiepiscopal rank.
On 5 December 2009 Pope Benedict XVI re-erected the residential Diocese of Sisak, resurrecting the titular title and splitting off its present territory from its metropolitan, the Archdiocese of Zagreb, an unusual instance of a titular diocese of the Catholic Church becoming a residential one again. On the same day the Pope erected the new Diocese of Bjelovar-Križevci, also within the Ecclesiastical province of Zagreb in Croatia.

, it pastorally served 163,844 Catholics on 5,500 km² in 77 parishes with 63 priests, 102 lay religious and 8 seminarians.
