Dan Brown got some details wrong in The Da Vinci Code, but this large church is still worth a visit — especially if you’re planning to hit the Luxembourg Gardens.

Église Saint-Sulpice
12 Place Saint-Sulpice
75005 Paris, France

• Saint-Sulpice is the second-largest church in Paris, behind Notre-Dame.

• It’s located in the 6th arrondissement, in the fashionable Saint-Germain-des-Près district.

• The Catholic church is dedicated to Saint Sulpicius the Pious, a 7th century bishop of Bourges, who spoke out against the Merovingian kings.

• Construction of the church ran from 1646 to 1745, dragging out for a century mostly due to inconsistent funding. It’s done in a muted Baroque style.

• Saint-Sulpice was where the S&M enthusiast the Marquis de Sade and the poet Charles Baudelaire were baptized, and it hosted the wedding of author Victor Hugo.

• It boasts iconic mismatched towers.

• The church is home to one of the most magnificent organs in the world.

• It’s known as the Cathedral of the Rive Gauche, or Left Bank.

• Saint-Sulpice became even more famous by being featured in a scene in Dan Brown’s The Da Vinci Code involving its gnomon, an astronomical instrument erroneously depicted as the site of the Rose Line.

• How do you pronounce Saint-Sulpice? Try saying “Seh Sool-Peez.”

We had spent the morning wandering the Luxembourg Gardens. Our friends Kent and Michael, who live in Paris, suggested we make the short walk to see l’Église Saint-Sulpice. We’re glad we did.

Fontaine Saint-Sulpice

A block from the gardens, we entered a small square with a fountain dominating the space. It’s quite an impressive work, with lions lying down but roaring grumpily, just like our cat Caribou. The Fontaine Saint-Sulpice was constructed between 1843 and 1848 by the architect Louis Visconti, who also designed Napoleon’s tomb.

At the top, in a rectangular structure built of arches, four assumably famous dudes sit majestically, starting out in each of the cardinal directions. Apparently, they were all created by different sculptors and represent religious figures who were known for having the gift of gab.

Église Saint-Sulpice

The Church of Saint-Sulpice now stands where a small Romanesque church once catered to the neighborhood, long before the Saint-Germain-des-Près district was home to the existentialists (Sartre and the gang) or the posh hot spot it is today.

Like many large churches, it took a long time to build — about a century — mainly due to touch-and-go funding, with various architects contributing different designs along the way. Construction began in 1646 but stalled from 1678 to 1719. It then resumed, mostly wrapping up by 1745.

Nicknamed the Cathedral of the Rive Gauche (Left Bank), Saint-Sulpice is one of the largest churches in Paris, second only to Notre-Dame. Its design is actually quite plain for the typically frilly and ornate Baroque style. You’ll also notice that it’s slightly asymmetrical, as the south tower was never finished. Construction was interrupted by the French Revolution and never completed. Stacks of open colonnades line the exterior, evoking the Roman Colosseum.

Saint-Sulpice Church is renowned for its massive organ, considered one of the finest (and largest) in the world. It dates back to 1781 and was the highlight of Aristide Cavaillé-Coll’s career. Because of this impressive instrument, concerts are frequently held in the church.

Nowhere near as popular as other churches, like Notre-Dame or Sacré-Cœur, this feels very much like a neighborhood place of worship, and chances are you’ll be able to wander it without many other tourists around. When we visited, there was a small wedding going on at the very front of the church, and we watched the bride and her father weave their way through the space, heading up the aisle.

One thing that particularly struck us is the lack of pews — instead, there are rows upon rows of small wooden chairs with woven seats.

The Da Vinci Code Connection

There it is.

Embedded in the gray granite floor, a thin polished strip of brass glistened in the stone … a golden line slanting across the church’s floor. The line bore graduated markings, like a ruler. It was a gnomon, Silas had been told, a pagan astronomical device like a sundial. Tourists, scientists, historians, and pagans from around the world came to Saint‑Sulpice to gaze upon this famous line.

The Rose Line.

…. It was an ancient sundial of sorts, a vestige of the pagan temple that had once stood on this very spot. The sun’s rays, shining through the oculus on the south wall, moved farther down the line every day, indicating the passage of time, from solstice to solstice.

–“The Da Vinci Code,” Chapter 22, Dan Brown

Saint-Sulpice has another claim to fame: It’s featured in Dan Brown’s fun puzzle romp The Da Vinci Code — both the book, quoted above, and the crappy movie version.

The narrow brass strip is used as a clue by Silas, the murderous monk, in his quest for the Holy Grail. One end is found near the middle of the nave on the right, by a stone statue with a Latin inscription. From there, it runs north, leading to an obelisk next to a statue of Saint Peter.

This is the famous gnomon — technically, the projecting piece on a sundial that shows the time by the position of its shadow. In this case, it’s a line that’s used as an astronomical instrument from the 1700s to determine the suspiciously pagan date of Easter each year (the first Sunday after the first full moon on or after the vernal equinox — it doesn’t get any more pagan than that!). The sun’s rays enter the church through a missing panel in the south transept’s stained glass window and fall upon the line at various points throughout the year. On the spring and autumn equinoxes the sun hits a bronze table, and on the winter solstice, it illuminates the obelisk.

Brown calls this line the Paris Meridian, or the Rose Line, but apparently that’s pure fiction: Zero longitude of the meridian line is actually in Parc Montsouris, according to Travel France Online.

Because of the influx of Da Vinci Code aficionados (visitations increased 25% after the publication of the novel, apparently), Saint-Sulpice posted the following note in English:

Well, The Da Vinci Code version makes a good story. But even the facts are not without interest, in providing an example of the cooperation of science and religion. It would not be unreasonable to expect the church was built on a pagan temple; this was a regular practice. However, it seems unlikely that the sundial, especially if known to be pagan, would have been preserved or reconstructed in the new church building.

Despite the fact that Brown manipulated the facts a bit to make a more compelling story, Saint-Sulpice is definitely worth a wander, especially when paired with the Luxembourg Gardens. –Wally
