When the Roof Is a Work of Art: The Stained-Glass Dome of Galeries Lafayette

Dome

On the same trip to Paris where I stood on a rooftop terrace admiring the copper dome of the Palais Garnier, I walked into one of the most breathtaking interiors I have ever seen. I looked up, and there it was: an enormous stained-glass dome glowing with colored light, floating above a grand hall like a sky made of art. This is the famous Coupole of Galeries Lafayette.

Now, I want to be honest with you. This is not a roof we would ever build. We work in natural slate, clay tile, and copper, not stained glass, and a department store's glass cupola is far outside our trade. But it crowns a building the way our roofs crown the homes and churches we work on, and it is such a stunning piece of architectural craftsmanship that I could not resist sharing it here alongside the roofs I have been writing about. Sometimes beauty is worth mentioning simply because it is beautiful.

A Glass Sky Above a Grand Hall

The Galeries Lafayette dome was unveiled on October 8, 1912, at the flagship store on Boulevard Haussmann. It rises roughly 43 meters above the central hall in a dazzling Art Nouveau and Neo-Byzantine style. The dome is composed of ten petal-like bays that together form a giant floral motif, spanning about 1,000 square meters of stained glass.

The effect from below is unforgettable. Golden and jewel-toned light filters down through the glass, washing across the balconies and the shoppers far below. Over a century after it was built, it remains one of the most photographed interior features in all of Paris, and it is a listed historic monument.

The Craftsmen Who Built It

What struck me most, as someone who spends her days around roofing craftsmen, is that this dome was not the work of one person. It was a collaboration of specialists, each a master of a single material. The architect Ferdinand Chanut designed the overall geometry and structure. The renowned glassmaker Jacques Grüber, of the celebrated École de Nancy, created the stained-glass panels. Louis Majorelle crafted the gilded ironwork of the balconies, and Édouard Schenck designed the floral detailing on the metal arches.

That is exactly how a great roof comes together, too. The finest work overhead, whether stained glass in Paris or a slate and copper roof here in North Carolina, is almost never a one-person job. It is the product of different trades, each doing what they do best, brought together with care.

The "Fifth Facade"

Architects sometimes call the roof a building's "fifth facade," the surface you do not walk past but look up to. The Galeries Lafayette dome is a glorious reminder of that idea. A building's crown, whether it is a glass cupola, a copper dome, or a slate roof, is what gives the structure its silhouette against the sky and its identity from within.

Whether the material is glass that colors the light or copper that ages to green or slate that has protected a home for a hundred years, the top of a building is where artistry and engineering meet. It is the part people remember.

Built to Last, and Lovingly Restored

Here is the part that speaks most directly to what we value. The Coupole is not just old and beautiful; it has been carefully preserved. Between 2020 and 2021, the dome underwent one of the largest restorations in the store's history. The stained-glass panels were dismantled and restored, the aging structure behind them was rebuilt, and much of the work was carried out at night so the store below could keep functioning.

That is the same philosophy we bring to historic roofs. When a slate or copper roof has stood for a century, the goal is to honor and preserve what is worth keeping, repairing and restoring rather than tearing away irreplaceable character. A great roof, like a great dome, deserves to be maintained for the next generation, not simply discarded.

Look Up

There is a saying about Galeries Lafayette: shop till you drop, but do not forget to look up. I would offer the same advice about buildings everywhere. So much of the beauty in our built world lives overhead, in the domes, cupolas, and roofs we hurry beneath without noticing. From the store's rooftop terrace you can look out over the roofs of Paris and the copper dome of the opera house next door, a whole skyline of craftsmanship most people never pause to see.

While we will always leave the stained glass to the masters of Nancy, we share their reverence for what crowns a building. At Carolina Slate, natural slate, Ludowici clay tile, and copper are our materials, and beauty that lasts is our goal. Ricardo brings more than three decades of hands-on experience to every project, with the same respect for craft and history that keeps a 1912 dome glowing over Paris to this day.

If you have a historic home, church, or landmark in North Carolina whose roof deserves that kind of care, we would love to talk. And wherever you are, do not forget to look up.
