It’s summer and that, of course, means travel. And when people go places, the common thing for them to do in the last few years is check-in and let all of their friends know exactly where they are and what they’re doing.

Facebook looked at all the check-ins made on Facebook as well as third-party apps that use the Facebook API. Using this data, they determined the top “social landmarks” across 25 different highly social cites. These “highly social” cities include Dublin, Chicago, Toronto, Berlin, Melbourne, Buenos Aires, and more from nearly all corners of the world.

Facebook found that the most likely place for check-ins is a sports stadium. Across the 25 cities look at, 7 of the top social landmarks were either stadiums or arenas – for instance the top attraction according to check-ins in Chicago was Wrigley Field. In San Francisco is was AT&T Ballpark and in Los Angeles is was the Staples Center. Close behind sports stadiums was public areas like avenues, squares, and gardens. These spaces were the most popular for check-ins in cities like New York (Times Square), Paris (Avenue des Champs-Élysées), and São Paulo (Parque do Ibirapuero).

Facebook says they also found some often surprising things about check-ins in certain cities –

We found some interesting comparisons within individual cities. In New York, the American Museum of Natural History garnered more check-ins than its neighbor across Central Park, the Metropolitan Museum of Art. Rome’s Spanish Steps is one the city’s most social spots followed by the Trevi Fountain, just 10 minutes away. City architectural treasures and famous green spaces were popular throughout New York, Berlin, London, Rome – and Paris, where the Avenue des Champs-Élysées beat out the famous Eiffel Tower.
