Palmyra's ancient Triumphal Arch, destroyed last year during the conflict in Syria, has been resurrected in London's Trafalgar square.
The scale reproduction of the 2,000 year old monument was created using state-of-the-art 3-D printing and carving technologies.
The replica is intended as an act of defiance against ISIS.
The project was carried out by Oxford's Institute for Digital Archaeology (IDA), a joint venture between Harvard University, Oxford University and Dubai's Museum of the Future.
"Monuments, as embodiments of history, religion, art and science, are significant and complex repositories of cultural narratives," said IDA Director Roger Michel.
"No one should consider for one second giving terrorists the power to delete such objects from our collective cultural record," continued Michel. "When history is erased in this fashion, it must be promptly and, of course, thoughtfully restored ... No one would have seriously considered leaving London in ruins after the Blitz."
The newly constructed arch is being unveiled to coincide with World Heritage Week, which runs from April 19-21. The structure will be on display in London for three days before beginning a world tour.
Other cities set to host the Triumph Arch replica include New York and Dubai.
"The life of the Syrian people rests on their cultural identity, and Palmyra represents one of the most unique and exceptional cultural heritage sites, not just in Syria but the whole world," said Syria's top antiquities official, Dr. Maamoun Abdulkarim, director-general of Antiquities and Museums.
"We know that the plans to restore Palmyra to its former glory are grand, but they can be realized if the task is treated as a global mission," added Abdulkarim.
Made of Egyptian marble and constructed in Italy, the reconstructed arch will preserve the appearance of the original structure in minute detail.
Weighing nearly 11 tons and standing approximately 20 feet tall, the project presents both a technical and engineering challenge.
Crews carefully assemble the replica arch.
