Again, there are more popular churches to see when visiting Paris. But that's precisely why too many miss this gem.
The baroque Roman Catholic Eglise Saint-Sulpice, located in the Sixth Arrondissement, was a pivotal backdrop in “The Da Vinci Code.” Built in the 17th century, it is one of the city’s largest churches, and featured the fictional Rose Line in the Dan Brown novel and movie. The actual line is a gnomon, or sundial, that calculates the winter and summer solstices, and is not, in fact, the Paris Meridian, as the movie will have you believe.
However, the church is beautiful and the gnomon is an architectural wonder, so swing by when in Saint-Germain-des-Près.
