This busy square sits at the southern end of Bordeaux’s Old Town and is a popular hangout, especially among students. The 18th-century Porte d’Aquitaine marks one of the city’s old entrances, while a tall obelisk and two bronze tortoises — added in 2005 by Czech sculptor Ivan Theimer — celebrate Bordeaux’s wine culture. Look closely and you’ll spot grape clusters and appellations carved into the sculptures. Around the square, you’ll find casual bars, kebab shops, and small boutiques. It’s more a spot to grab a drink or soak up the atmosphere than a must-see, but it’s a good place to get a feel for local life.
