Made famous by Dan Brown's bestselling novel The Da Vinci Code, the Church of St Sulpice in the 6th arrondissement, not far from the Luxembourg Garden, also has some remarkable architectural features. Founded in the 12th century then rebuilt in the 17th, this imposing and majestic church is a listed Historic Monument and one of the biggest churches in Paris!
So before you step over its threshold, take the time to admire its monumental façade designed by the Florentine Giovanni Niccolò Servandoni. Once inside, you can discover the beautiful Baroque Chapel of the Virgin, the great organ, the amazing gnomon, an astronomical measuring instrument in the transept, and the magnificent paintings by Eugène Delacroix in the Chapel of Holy Angels.
On the church's forecourt stands a superb 19th-century fountain by the architect Louis Visconti, adorned with four statues of great Catholic orators.
