The fine brass line that runs through St-Sulpice draws many Da Vinci Code fans.

St-Sulpice

From the obelisk of St-Sulpice runs a brass line across the church floor—a line built in the 1720s to determine the day Easter should be observed.

The church is located on Paris’s Left Bank near the Sorbonne. Also nearby, the two of you can stroll hand-in-hand in the Luxembourg Gardens, the perfect spot for an afternoon of people watching.
