The See of Sardis or Sardes (Greek: Σάρδεις, Sardeis) was an episcopal see in the city of that name. It was one of the Seven Churches of the Apocalypse, held by metropolitan bishops since the middle to late 1st century,[1] with jurisdiction over the province of Lydia, when this was formed in 295. After 1369 it became a titular see both for the Greek Orthodox Church and the Roman Catholic Church.
