ROME — Venice authorities on Thursday unveiled a pilot program to charge day-trippers 5 euros ($5.45) apiece to enter the fragile lagoon city on peak weekends next year in an effort to reduce crowds, encourage longer visits and improve the quality of life for residents.

       The rollout of the tourist “contribution” program came after Venice, a UNESCO World Heritage site, narrowly escaped being placed on the U.N. agency’s danger list earlier this year because of the threat that overtourism was having on its delicate ecosystem. Member states cited the proposed new entry fee in deciding to spare Venice from the list.

       Venice Mayor Luigi Brugnaro stressed Thursday that the fee is not a new tourist tax or an attempt to bring in extra revenue. Rather, he said, it is a first-of-its-kind experiment in regulating tourist flows in one of the world’s most-visited places by incentivizing visitors to avoid high-traffic periods and come on other days.
