Church in Avignon, France
It's impossible to talk about Avignon without mentioning the celebrated Popes' Palace, listed as UNESCO World Heritage site. Given the Palace's colossal size, looming over the town, it's perhaps no surprise that this is the biggest gothic palace in the world. While it's largely famous for its 14th-century heyday as a papal capital and its even older 12th-century bridge, Avignon has plenty to offer beyond history.
