Abbaye Saint Victor in Marseille may not be at the top of everyone's to-see list, especially when the nearby, picturesque Notre Dame Basilica and its bird's-eye view are such a big draw. But there are two reasons this abbey should be added: First, it's a convenient stop on the way to Notre Dame, and secondly, it is commonly considered the oldest church in France–which is quite a claim, considering that thousand-year-old churches seem to be a dime a dozen here.
In fact, the abbey's history dates back to the fifth century, was in ruins by the ninth century and by the 13th century, when other world-famous churches were first being built, Abbaye Saint Victor was being renovated. Martyrs died here, the library was dismantled simply to please a de Medici family member, and in the late 18th century, the site was stripped of all of its finery. In short, it's had quite a history.
