NEWPALMYRA

In 2012, Khartabil was arrested, and the original project and open source files were lost. Barry Threw took over as director of the project, renamed #NEWPALMYRA, and a community of developers, modelers, and archaeologists began collaborating to model, restore, and later recreate from scratch those historical structures captured on film and camera.
In 2015, ISIL captured Palmyra and began destroying some of its famous historical sites. In late 2015, the Institute for Digital Archaeology began contributing to the New Palmyra Project, sending archaeologists with cheap 3D cameras to capture any further structures that ISIL might decide to destroy.
3D models.
One of the best known structures in Palmyra was the monumental Arch of Triumph (قوس النصر). Constructed during the reign of Emperor Septimius Severus (193 to 211), it was sometimes mistakenly referred to as Hadrian’s arch. It was restored in the 1930s, and then destroyed completely during the Syrian Civil War in 2015.
Palmyra's main streets were not at right angles, and this arch was famously built at a 30-degree turn in the colonnade between the tetrapylon (التترابيل) and the Temple of Bel (معبد بل), with two richly carved façades angled away from one another.
A square platform, each corner containing a group of four columns. This was erected during the renovations of Diocletian at the end of the 3rd century. Each column had a pedestal in its center that originally supported a statue. The original columns were brought from Egypt and carved out of pink granite. Only one was undamaged in 1963 when the whole was restored with concrete. Destroyed again by ISIL on January 20, 2017.
This ancient temple was dedicated to the Mesopotamian god Bel in 32 AD. Bel was worshipped at Palmyra along with the moon god Aglibol and the sun god Yarhibol. The ruins of the temple were among the best preserved at Palmyra. they were destroyed by ISIL in August, 2015.
The Roman Theatre at Palmyra (المسرح الروماني بتدمر) dates to the time of Severus. Its remains were restored in the 20th century, and it served for a time as a venue for the annual Palmyra festival. It was destroyed by ISIL in May 2015.
The Temple of Baal Shamin dates to the 2nd century BC, and dedicated to the Canaanite sky deity. Its altar was built in 115 AD, and the temple was rebuilt in 131 AD. In the 5th century AD, it was converted to a church. In 2015 it was destroyed by ISIL.
This was the first statue modeled by #rsssd (Re-Sculpting Syrian Statues Digitally). In 2015 it was destroyed by ISIL.
Reconstructions and exhibits.
A 12-ton lifesize replica of part of the Arch of Triumph was carved into stone, from these models, and installed in London's Trafalgar Square in 2016.
A number of small artefacts were reconstructed and displayed at the 2016 Venice Architecture Biennale.
A 10-foot model of part of the Tetrapylon, printed in a single piece, was unveiled at the April 2017 Creative Commons Summit.
Popular discussion.
The project began to hold public events, partner with design groups and 3D printing shops, and receive press coverage starting in 2015.
"Reviving Palmyra", a book on the history, destruction, and reconstruction of Palmyra, was published in 2017.
