About 200,000 Palestinian Christians currently reside in the Holy Land, descendants of some of the oldest Christian communities in the world. The Church of the Holy Sepulchre, Christianity's most holy site, as well as the Via Dolorosa, the route Christ is believed to have walked to his crucifixion, are located within Jerusalem’s Old City. Israel forbids Palestinians living in the occupied West Bank and Gaza to enter Jerusalem without permits, which are extremely difficult to obtain. Christian Palestinians who are citizens of Israel also suffer from widespread discrimination.
