Church of the Sepulchre of Saint Mary, also Tomb of the Virgin Mary , is a Christian tomb in the Kidron Valley – at the foot of Mount of Olives, in Jerusalem – believed by Eastern Christians to be the burial place of Mary, the mother of Jesus. The Status Quo, a 250-year old understanding between religious communities, applies to the site.
