Manger Square is a city square in the center of Bethlehem in Palestine. It takes its name from the manger where Jesus is said to have been born which, according to Christian tradition, took place at the Nativity Church. A particular building set in Manger Square is the Mosque of Omar, the city's only mosque, and the Palestinian Peace Center. The streets that lead to the square are related to the Christian faith, such as Star Street and Nativity Street. In 1998-1999, the square was renovated to relieve the traffic congestion and currently is pedestrian only. It is mainly a meeting place for locals and for the town's many pilgrims. There are rows of celtis australis that provide shade to its people, with benches and fountains made of white yellowish Naqab marble below. Manger Square is a focal point for all of the Christmas celebrations in Bethlehem, with a giant Christmas tree crowning the square. It is the traditional spot where locals and pilgrims sing Christmas carols before the midnight mass at the Church of the Nativity. The Greek Orthodox Patriarchate of Jerusalem and the Armenian Apostolic Church follow the Julian Calendar liturgically, whereas the Roman Catholic Church follows the modern Gregorian Calendar. Thus Christmas Eve services for the Eastern and Western confessions are held on different days. The Roman Catholic Church celebrates the Nativity on December 25; the Orthodox celebrations are on January 7.
