The scope of this thing is pretty amazing - a temporary structure filling the whole square, surrounded by live plants and security men dressed in black. Turns out it is all for a wedding for a billionaire's daughter in the plastics industry. Seems sort of ostentatious in today's world (especially for this country with all of the political and social problems of the moment), but this is probably not much compared to what the Medici and others used to pull off for their own weddings back in the day :)
