Panthéon vs Les Invalides vs Sacré-Cœur
Three great domes, three different cities — Left Bank neoclassical, Right Bank imperial, Montmartre Byzantine
Three domes dominate the Parisian skyline beyond the Eiffel Tower: the Panthéon on the Left Bank, the Dôme des Invalides across the Seine, and the Sacré-Cœur on the Butte Montmartre. Each was built for a different purpose and represents a different architectural tradition. Visitors who try to see all three in a single day often leave confused about what they have seen; visitors who understand the differences in advance get more from each. This guide separates them.
The buildings — neoclassical, imperial baroque, Romano-Byzantine
The Panthéon was begun in 1758 by Jacques-Germain Soufflot as the church of Sainte-Geneviève and completed in 1790 by his pupil Jean-Baptiste Rondelet. Its design references the ancient Roman Pantheon and Saint Peter's in Rome — a Greek-cross plan, a colossal portico of Corinthian columns, and a triple-shelled dome rising 83 metres above the Place du Panthéon. Soufflot's structural ambition was so extreme — slender piers supporting an enormous dome — that the building had to be reinforced during construction and again in the nineteenth century. The result is one of the most architecturally daring buildings in pre-revolutionary France.
The Dôme des Invalides (1677–1706, by Jules Hardouin-Mansart for Louis XIV) and the Sacré-Cœur (1875–1914, by Paul Abadie) represent two later traditions entirely. The Dôme is the high baroque masterpiece of Mansart's career: a Greek-cross plan, a gilded dome inscribed with Old Testament prophets, an interior built around the imperial axis that would later receive Napoleon's tomb in 1840. The Sacré-Cœur is Romano-Byzantine — round arches, mosaics, white travertine that self-cleans in rain — and was built as a national vow of expiation after the disasters of 1870–71. Three buildings, three architectural worlds, no two reading as part of the same Paris.
What's inside — burials, tombs, mosaics
The Panthéon's crypt contains the remains of approximately eighty distinguished French citizens — Voltaire, Rousseau, Hugo, Zola, Dumas, the Curies, Malraux, Jean Moulin, Simone Veil, and the Manouchians among the most-visited. The nave above the crypt houses Foucault's pendulum (the 1851 demonstration of the Earth's rotation) and a series of nineteenth-century murals on the life of Sainte-Geneviève. The Dôme des Invalides centres on Napoleon's tomb — a six-layered sarcophagus in red porphyry placed in a circular opening in the floor — surrounded by the tombs of his son the Duke of Reichstadt, his brothers Joseph and Jérôme, and the military leaders Foch, Turenne, Vauban, and Lyautey.
The Sacré-Cœur has a different programme entirely. There is no burial cycle and no central tomb. The interior is dominated by an immense mosaic in the apse — Christ in Majesty surrounded by France in adoration, completed in 1922 — which at 480 square metres remains among the largest mosaics in the world. Below the basilica is a small crypt with the tomb of the basilica's architect Paul Abadie. Most visitors come for the apse mosaic and for the view from the basilica's exterior dome (an additional climb above the rooftop terrace) which offers the highest publicly accessible view in Paris after the Eiffel Tower.
The view — what you can see from each dome
The Panthéon's dome colonnade (open April to October) sits at the 35-metre level and looks across the Left Bank with the Eiffel Tower to the west, Les Invalides to the north-west, Notre-Dame and the Latin Quarter rooftops in the foreground, and the Sacré-Cœur on Montmartre to the north. The view is the most architecturally legible of the three because the foreground rooftops are at a readable scale. The Dôme des Invalides itself is not climbable — the dome is sealed above the tomb chamber — but the surrounding Cour d'honneur and the Esplanade des Invalides give a strong ground-level view of the gilded exterior.
The Sacré-Cœur's outer dome climb takes 300 steps and reaches 83 metres above the basilica floor — which is itself perched 130 metres above the Seine on the Butte Montmartre. Total elevation of the dome viewing platform is around 213 metres above the Seine, making it the second-highest publicly accessible view in Paris after the Eiffel Tower summit. The view is from a Right Bank vantage and shows the Sacré-Cœur's own surroundings in the foreground (the steep Montmartre streets), the Opéra district middle-ground, and the Eiffel Tower and Les Invalides distant. It is a different city from the Panthéon view, not better or worse.
Crowds, queues, and ticketing
The Sacré-Cœur is the most-visited of the three by a wide margin — roughly 10 million visitors annually to the basilica itself, free of charge with no reservation. The dome climb requires a separate paid ticket and has its own modest queue. The Panthéon receives roughly 800,000 paid visitors a year and operates timed-entry with reservation strongly recommended in summer. The Dôme des Invalides is part of the Musée de l'Armée complex (around 1.4 million visitors a year) and is included in the museum ticket; reservation is not required but improves the experience in peak hours.
Pricing is straightforward at all three. The Panthéon is a Centre des monuments nationaux site with a single combined ticket covering the nave, crypt, and (in season) the dome colonnade. Les Invalides is a Musée de l'Armée ticket covering the dome chapel, Napoleon's tomb, and the military museum housed in the surrounding buildings. The Sacré-Cœur basilica is free; the dome climb costs a small separate fee paid on the day. Visitors with a Paris Museum Pass can use it at the Panthéon and Les Invalides; the Sacré-Cœur is not included because it is operated by the Catholic Church rather than the French state.
Combining the three — and which to skip if you must
All three can be combined in a single day, but the day is long and the geographic spread is real. The Panthéon and Les Invalides are connected by a 25-minute walk across the Seine via the Pont Alexandre III or a 15-minute Métro ride (Line 13 from Solférino to Saint-François-Xavier with one change). From Les Invalides to the Sacré-Cœur is a 35-minute Métro journey (Line 13 then Line 12) or a longer walk through the Tuileries. A practical sequence: Panthéon morning (10:00–12:00), lunch on the Left Bank, Les Invalides afternoon (14:00–17:00), Sacré-Cœur evening (18:00–sunset).
If you can only visit one, the answer depends on what you want to take away. Architecture and intellectual history: the Panthéon. French military history and the Napoleonic story: Les Invalides. Highest view, mosaics, and the Montmartre experience: the Sacré-Cœur. The three are not interchangeable substitutes — they answer different questions about Paris. Visitors who treat them as a single 'domes of Paris' itinerary often arrive at the third one tired and disengaged. Better to choose one or two and visit them with attention than to tick all three and remember none.
常见问题
Which is the oldest of the three?
The Dôme des Invalides (1677–1706) is the oldest. The Panthéon followed (1758–1790). The Sacré-Cœur is the youngest (1875–1914).
Is Napoleon buried in the Panthéon?
No. Napoleon's tomb is in the Dôme des Invalides, not in the Panthéon. The Panthéon holds the remains of distinguished civilian figures — philosophers, writers, scientists, and resistance heroes — but not Napoleon or members of the imperial family.
Which has the best view?
The Sacré-Cœur dome — at roughly 213 metres above the Seine, it is the second-highest publicly accessible view in Paris after the Eiffel Tower summit. The Panthéon dome (35 metres above the Place du Panthéon, roughly 95 metres above sea level) gives a more architecturally readable view at film-camera height.
Is the Sacré-Cœur free?
Yes — the basilica is free with no reservation. The dome climb requires a small separate paid ticket. The Panthéon and Les Invalides both require paid tickets.
Can I climb the Dôme des Invalides?
No — the dome is sealed above the tomb chamber and not accessible to visitors. The ground-floor view of Napoleon's tomb from the gallery surrounding the central opening is the headline experience.
Can I visit all three in one day?
Yes, but the day is long. Plan Panthéon morning, Les Invalides afternoon, Sacré-Cœur evening. Total visiting time is around six hours plus transit.
Which is the most crowded?
The Sacré-Cœur — roughly 10 million visitors annually to the basilica. The Panthéon is the quietest of the three at around 800,000 paid visitors a year. Les Invalides sits in between.
Is the Paris Museum Pass accepted?
Yes for the Panthéon and Les Invalides. The Sacré-Cœur is not included because it is operated by the Catholic Church rather than the French state.
How many steps to the Sacré-Cœur dome?
Approximately 300 steps from the basilica floor to the dome viewing platform. There is no lift.
Which has the best mosaics?
The Sacré-Cœur — its apse mosaic of Christ in Majesty (completed 1922) is 480 square metres and is among the largest in the world. The Panthéon and Les Invalides have important nineteenth-century murals but no comparable mosaic programme.
