Palmyra's Arch of Triumph recreated in Trafalgar Square

Faithful copy of ancient Syrian monument destroyed by Isis will stand in central London for three days

A monumental recreation of the destroyed Arch of Triumph in Palmyra, Syria, has been unveiled in London's Trafalgar Square.

The 1,800-year-old arch was destroyed by Islamic State militants last October and the 6-metre (20ft) model, made in Italy from Egyptian marble, is intended as an act of defiance: to show that restoration of the ancient site is possible if the will is there.
