A year after the ancient city of Palmyra, Syria was destroyed by the Islamic State, a 3D-printed recreation of one of its most iconic structures has begun its world tour. Originally erected in London’s Trafalgar square in April, on Monday, the replica of Palmyra’s Arch of Triumph was unveiled in its new location outside city hall in New York City. Two-thirds the scale of the original, the reconstructed arch was carved from Egyptian marble blocks using a team of Italian stone-carving robots, which followed a 3D model of the arch assembled from photographs taken of the structure prior to its demise. For centuries, the 1,800-year-old arch served as the entrance to the Temple of Bel, the center of religious life in Palmyra. Even after the city’s abandonment, the monument remained an important example of Roman architecture in the Middle East.
