Callipolis remains a Roman Catholic titular bishopric in the former Roman province of Thrace.
Callipolis was a suffragan of Heraclea. Lequien (I, 1123) mentions only six Greek bishops, the first as being present at the First Council of Ephesus in 431, when the see was united to that of Coela(Coelia or Coele), the last about 1500. His list could easily be increased, for the Greek Orthodox see still exists; it was raised in 1904 to the rank of a metropolis without suffragans, after the manner of most Greek metropolitan sees. Lequien (III, 971) also gives the names of eight Latin bishops from 1208 to 1518. (See Eubel, I, 269, note.) There are numerous schools and a small museum; a large cemetery is the resting place of many French soldiers who died of disease (chiefly cholera) during the Crimean War. The port is poor and trade unimportant, for want of roads. A Catholic mission was conducted in the Ottoman days by Assumpionist Fathers; there are also a number of Armenian and Greek Catholics, with priests of their respective rites
