Roman Catholic Archdiocese of Chersonesus in Zechia

The Roman Catholic Archdiocese of Chersonesus in Zechia, is a titular diocese formerly based in Sevastapol, Crimea.

In 1333, a Latin Church diocese of Chersonesus was established, but it appears that it had only a bishop, a Dominican called Richard the Englishman.

No longer a residential diocese, Chersonesus in Zechia is today listed by the Catholic Church as a titular archbishopric, since the early 20th century, originally called Cherson(a) or Chersonesus, since 1933 specifically Chersonesus in Zechia, avoiding confusion with other sees called Chersonesus (notably in Crete) by specifying it is Crimean.
