Rome's Colosseum is synonymous with the city and it has to be one of the most visited locations.
But these buildings require immense care and 2014 brought to an end a restoration project that cost an estimated £21m.
Although it remained open for the duration, there was inevitably some disruption – especially for the photographers. Two thousand years of pollution had blackened the stonework – and damage caused by the vibration of the nearby metro also required attention. As necessary as all this work is, it is bitterly disappointing for visitors.
