On Tuesday a new structure was built in Trafalgar Square, a replica of the Syrian Palmyra Arch that was destroyed by ISIS. When you do building work though you should always consider the impact on your neighbours. In this case, the Square's most notable resident was given a face mask so he didn't have to breath in any dust.
The arch is only in London for three days as it is going on a world tour that will include New York, Dubai and Palmyra itself.
