PARIS (AP) -- When Olivier Baroin moved into an apartment in Montmartre about 15 years ago, it felt like he was living in a village in the heart of Paris. Not anymore.

Stores for residents are disappearing, along with the friendly atmosphere, he says. In their place are hordes of people shooting selfies, shops selling tourist trinkets and cafés whose seating spills into the narrow cobbled streets as overtourism takes its toll.

Baroin has had enough. He put his apartment up for sale after local streets were designated pedestrian-only while accommodating the growing number of visitors.

"I told myself that I had no other choice but to leave since, as I have a disability, it's even more complicated when you can no longer take your car, when you have to call a taxi from morning to night," he told The Associated Press.

From Venice to Barcelona to Amsterdam, European cities are struggling to absorb surging numbers of tourists.

Some residents in one of Paris' most popular neighborhoods for tourists are now pushing back. A black banner strung between two balconies in Montmartre reads, in English: "Behind the postcard: locals mistreated by the Mayor." Another, in French, says: "Montmartre residents resisting."

Atop the hill where the Basilica of Sacré-Coeur crowns the city's skyline, residents lament what they call the "Disneyfication" of the once-bohemian slice of Paris. The basilica says it now attracts up to 11 million people a year -- even more than the Eiffel Tower -- while daily life in the neighborhood has been overtaken by tuk-tuks, tour groups, photo queues and short-term rentals.

"Now, there are no more shops at all, there are no more food shops, so everything must be delivered," said 56-year-old Baroin, a member of a residents' protest group called Vivre a Montmartre, or Living in Montmartre.

The unrest echoes tensions across town at the Louvre Museum, where staff in June staged a brief wildcat strike over chronic overcrowding, understaffing and deteriorating conditions. The Louvre logged 8.7 million visitors in 2024, more than double what its infrastructure was designed to handle.

Paris, a city of just over 2 million residents if you count its sprawling suburbs, welcomed 48.7 million tourists in 2024, a 2% increase from the previous year.

Sacré-Coeur, the most visited monument in France in 2024, and the surrounding Montmartre neighborhood have turned into what some locals call an open-air theme park.

Local staples like butchers, bakeries and grocers are vanishing, replaced by ice-cream stalls, bubble-tea vendors and souvenir T-shirt stands.

Paris authorities did not immediately respond to requests for comment.

Visitors seemed largely to be enjoying the packed streets on a sunny Tuesday this week.

"For the most part, all of Paris has been pretty busy, but full of life, for sure," said American tourist Adam Davidson. "Coming from Washington, D.C., which is a lively city as well, I would say this is definitely full of life to a different degree for sure."

In Barcelona, thousands have taken to the streets this year, some wielding water pistols, demanding limits on cruise ships and short-term tourist rentals. Venice now charges an entry fee for day-trippers and caps visitor numbers. And in Athens, authorities are imposing a daily limit on visitors to the Acropolis, to protect the ancient monument from record-breaking tourist crowds.

Urban planners warn that historic neighborhoods risk becoming what some critics call "zombie cities" -- picturesque but lifeless, their residents displaced by short-term visitors.

Paris is trying to mitigate the problems by cracking down on short term rentals and unlicensed properties.

But tourism pressures are growing. By 2050, the world's population is projected to reach nearly 10 billion, according to United Nations estimates. With the global middle class expanding, low-cost flights booming and digital platforms guiding travelers to the same viral landmarks, many more visitors are expected in iconic cities like Paris.

The question now, residents say, is whether any space is left for those who call it home.
