Recreating Palmyra's Arch of Triumph using photogrammetry

The original Palmyra Arch stood for over 1700 years until its destruction in 2015 by Islamic State. With irreplaceable objects of immense cultural value at risk in warzones and vulnerable areas, impressive methods of preservation and recreation have been developed.

The Institute for Digital Archaeology created a 35 percent scale reproduction of the Arch using photogrammetry. Hundreds of two dimensional photographs were used to create a three dimensional model, which was then precisely carved out of marble using a CNC milling machine.
