Circa 1300 (possibly much earlier) was established a Diocese of Balecium alias Balezo.
At the beginning of the 14th century, Baleč (alias Baleš) was the see of a small Catholic diocese. In 1356, Bishop Andreas Citer complained that his bishopric was full of schismatics. The diocese had been laid waste and impoverished by Serbian "schismatics of the kingdom of Rascia", who had completely destroyed the monastery situated 5000 paces from the cathedral. In response, Pope Innocent VI granted him in commendam, on 26 September of the same year, the Benedictine monastery of St. John in Drivast. At this time Baleč must have ceased to exist as a town, so that, although bishops continued to be appointed to the see, by 1448, when even the fortress rebuilt by Skanderbeg was destroyed, the town was no more than a memory.
In the late 15th century the bishopric was formally suppressed after its see had been utterly destroyed.

Titular see
The bishopric of Balecium, no longer a residential see, is today listed by the Catholic Church as a titular see since it was nominally restored as Latin titular bishopric under the names Balecium (Latin; adjective Balcien(sis) ) or Balecio (Curiate Italian).
It has had the following incumbents, so far of the fitting episcopal (lowest) rank:
Claude Feidt (1980.07.05 – 1985.02.16) as Auxiliary Bishop of Archdiocese of Chambéry–Saint-Jean-de-Maurienne–Tarentaise (France) (1980.07.05 – 1985.02.16); later promoted Coadjutor Archbishop of Chambéry–Saint-Jean-de-Maurienne–Tarentaise (1985.02.16 – 1985.05.14), succeeding as Metropolitan Archbishop of Chambéry–Saint-Jean-de-Maurienne–Tarentaise (1985.05.14 – 1999.06.17), next last Metropolitan Archbishop of Aix(-en-Provence) (France) (1999.06.17 – 2002.12.08), see demoted Archbishop of Aix (2002.12.08 – retired 2010.03.29)
Peter Kang U-il (강우일 베드로) (1985.12.21 – 2002.07.20) as Auxiliary Bishop of Archdiocese of Seoul 서울 (South Korea) (1985.12.21 – 2002.07.20); later Bishop of Jeju 제주 (South Korea) (2002.07.20 – ...), President of Catholic Bishops’ Conference of Korea (2008.10.16 – 2014.10.30)

Јована у Дривасту. Као разлог за овај неуобичајен потез, јер Дриваст има свог епископа, наведено је да је манастир после смрти опата Андрије "растурен" од тамошњих шизматика, као и сама балечка дијецеза.
