Diocese of Horta

Horta was a city and bishopric in Roman Africa, which only remains as Latin Catholic titular see.

History
Horta, identified with Srâ-Orta in modern Tunisia, was among the many cities of sufficient importance in the Roman province of Africa Proconsularis, in the papal sway, to become a suffragan diocese of the Archbishopric of capital Carthage. Like many, it faded completely, plausibly at the 7th century advent of Islam.

Its only historically documented bishop, Donatus, partook in the Council of Carthage (646) against the heresy of monotheletism.

Titular see
The diocese was nominally restored in 1933 as Latin titular bishopric of Horta (Latin) / Orta (Curiate Italian) / Horten(sis) (Latin adjective)
