Under the gaze of the world's media, the fragile lagoon city of Venice launched a pilot program Thursday to charge day-trippers a 5-euro (around $5.35) entry fee that authorities hope will discourage visitors from arriving on peak days and make the city more livable for its dwindling residents.

Visitors arriving at Venice's main train station were greeted with large signs listing the 29 dates through July of the plan's test phase, as well as new entrances separating tourists from residents, students and workers.
