ROME - Rome's city authorities announced on Monday that it had begun measures to protect the city's famed Trevi Fountain, ahead of an influx of visitors for the 2025 Jubilee celebrations.

The 2025 Jubilee, a special celebratory year announced by the Vatican, the seat of the Catholic faith, is expected to attract millions of extra visitors to Rome, which is already among the world's most visited cities.

One of the city's most popular cultural and historical sites, the Trevi Fountain - a UNESCO World Heritage site - is on a small pedestrian square in the city center, meaning it easily becomes crowded during peak tourism periods.

The initiative, started Monday, combines regular maintenance efforts of the fountain with a redesign that will create a special walkway to give visitors a closer view of the site, while also ensuring a steady movement of visitors.

The redesign for the Trevi Fountain is part of a 1.2-million-euro ($1.3 million) plan to clean and reinforce four important Roman fountains: the main fountain of the Quirinale Palace, the Barcaccia Fountain at the Spanish Steps, and the Turtle Fountain in Rome's Ghetto neighborhood. The projects are financed by the European Union pandemic recovery funds.
