According to Turkish government resources, Pınarhisar was founded during the reign of Theodosius II, by c. 425, under the name "Brysis" meaning "spring" in Greek.

[3][4] The town was captured by the Ottomans in 1368, by the forces under the command of Ghazi Mihal, as a part of a campaign led by Murad I.

[3] The first mention of the archdiocese of Brysis is in an early 10th-century Notitia Episcopatuum associated with Emperor Leo VI the Wise.

[5][6][7] During the Fourth Crusade Brysis became a Latin Church archbishopric under the name Verissa (of Thrace).

[8] No longer a residential bishopric, Brysis is today listed by the Catholic Church as a titular see.
