Located in Bethlehem, a Palestinian city in the southern West Bank, the church is considered by many to be the birthplace of Jesus. It is a primary pilgrimage destination for most Christians. This building is the oldest standing church in the Holy Land. Originally built by Constantine’s mother in the 4th century, Emperor Justinian rebuilt the current structure around 530 CE.  http://www.justvision.org/glossary/church-nativity
