I went to the ILO today on Maestri del Lavoro. It is part of a UN cluster of buildings in Turin, together with UNICRI and a small UNESCO office, so the whole area is within a fenced up compound.
I realise that in most protected places in Turin, if you look not Italian/North European, you may get asked for your ID by the security guard at the entrance. I don't know what it is like at the other UN compounds in the rest of the world, but in this one, it works the other way around!
Due to the UN hiring quotas there are a whole lot of black/asian/women and other minorites walking in and out of the compound everyday. I have never been stopped to be asked for ID, but Fabien (white, male and therefore an endangered species) is always stopped at the entrance whenever he comes to get me.
