Croatian friar Sinisa Srebrerovic cleans the marble slab stone that covers the Tomb of Jesus, where his body is believed to have been laid, at the Church of the Holy Sepulchre in Jerusalem's Old City on March 2, 2018, a task that he does once every three weeks alternating between Greek Orthodox and Armenian priests. Dispatched to the city 800 years ago by the Catholic order's founder, Saint Francis of Assisi, the Franciscans have for centuries ensured a permanent Christian presence in the Holy Land. Pilgrims know them primarily as the Guardians of the Holy Sepulchre, protecting the site where Jesus is believed to have been crucified and buried. / AFP PHOTO / Thomas COEX
