Albi's massive Roman Catholic cathedral, St. Cécile, looks less like a church and more like a fortress — on purpose. It was built in a time when the pope felt compelled to make it clear that the only acceptable Christianity was Roman-style. Next to the church is the world's largest collection of art by Henri Toulouse-Lautrec. The museum displays his work chronologically, letting you follow the evolution of his art with his fascinating life's story.
