Our lives are structured by our memories of events. Event X happened just before the big Paris vacation. I was doing Y in the first summer after I learned to drive. Z happened the weekend after I landed my first job. We remember events by positioning them in time relative to other events.
In 2013, 47 million tourists visited Paris and the Paris region (including Disneyland Paris and Versailles). Paris remains year after year the most visited city in the world ahead of London and New York City.
