The Tomb of the Unknown Soldier and the 18:30 Eternal Flame Ceremony
What you can witness beneath the vault — the daily Ravivage de la Flamme since 1923, the slab interred in 1921, and the veterans' associations that have kept the flame burning through every Paris night for over a century.
Beneath the central vault of the Arc de Triomphe lies the Tomb of the Unknown Soldier — a marble slab that has held the remains of an unidentified French soldier of the First World War since 28 January 1921. The eternal flame above it was first lit on 11 November 1923 by André Maginot, then Minister of War, and has been rekindled every evening at 18:30 since that autumn, without a single interruption — including through the German occupation of 1940 to 1944. The ceremony is short, public, and almost entirely unguarded by velvet ropes: any visitor inside the Place Charles de Gaulle in late afternoon can step into the vault and witness it. This guide explains what actually happens at 18:30, who officiates, what the symbols on the slab mean, and how the etiquette differs from changing-of-the-guard rituals at other European monuments.
What the slab and the flame commemorate
The slab beneath the central vault marks the burial place of a single unidentified French soldier killed in the First World War. The coffin arrived at the Arc de Triomphe on 11 November 1920, the second anniversary of the Armistice, and lay in state in a chapel within the monument before final interment on 28 January 1921. The inscription on the slab reads, in French: 'Ici repose un soldat français mort pour la Patrie, 1914–1918' — 'Here rests a French soldier who died for the fatherland, 1914–1918.' The choice of an anonymous soldier was deliberate: the tomb stands for every French casualty of the war whose remains were never identified, and by extension for the unidentified dead of every later French conflict.
The eternal flame above the slab was added almost three years after the burial. It was lit for the first time on 11 November 1923 at 18:00 by André Maginot, then Minister of War, after a campaign by journalist Gabriel Boissy earlier that year. The bronze flame and its grille were designed by sculptor Henri Favier and architect Henri Edouard Nicod. Since the first relighting the following month, the flame has burned without ever being extinguished — the daily rekindling ceremony tops up the gas-fed burner rather than relighting a cold flame. It is, in continuous duration, the oldest such memorial flame in Western Europe.
The 18:30 ceremony — what actually happens
The Ravivage de la Flamme — the daily rekindling — runs every evening at 18:30, year-round, in roughly ten minutes. A small delegation, usually four to eight people drawn from a veterans' or commemorative association, enters the Place from the Champs-Élysées side at about 18:20, escorted by a uniformed marshal. They form a short procession to the slab, lay a wreath if the day has been allocated to a specific commemoration, and one delegate steps forward to revive the flame using a ceremonial sword that lifts the burner grille briefly. A bugler sounds Aux Morts (the French equivalent of Last Post), the delegation observes one minute of silence, and the Marseillaise plays. The delegation then signs the Livre d'Or, the gold-leaf register of officiants, kept in the monument's offices.
Visitors can stand at the edge of the cordoned area inside the vault throughout. There is no separate ticket, no advance booking, and no fee — the ceremony is held in a public memorial space, not behind the paid monument entry. Photography without flash is permitted; flash, loud conversation, and any approach inside the cordon are not. Weekday attendance is usually 20 to 60 onlookers; weekends and national-significance dates (8 May, 11 November, anniversaries of liberations) draw several hundred plus official delegations. If you have climbed the terrace earlier in the afternoon, plan to descend by 18:15 to find standing room near the cordon.
The Comité de la Flamme and the daily rotation
The ceremony is organised by an umbrella body founded in 1925, originally called La Flamme sous l'Arc de Triomphe and today widely known as the Comité de la Flamme. The Comité coordinates a rotation of roughly 700 affiliated French veterans' associations, regimental old-comrades societies, civil and youth movements, and foreign delegations — each of which is allocated specific evenings on which to provide the officiating delegation. The schedule is set a year in advance and published internally; a given association may officiate once or twice a year, depending on its size. As of 2022, the Comité was chaired by Lieutenant General Christophe de Saint-Chamas.
The rotation explains why the visual character of the ceremony shifts evening to evening. One night the delegation may be a handful of First-World-War-descendant associations in dark suits; the next may be a foreign embassy delegation with its own military attaché; the next a school group from a regional French commune attending in uniform. The ritual itself — the procession, the sword, the bugler, the silence, the anthem — is fixed and identical every night. Only the participants and the wreath vary. This is why the ceremony repays return visits: the choreography is constant, but the human content is renewed every twenty-four hours.
How this is different from changing-of-the-guard at other monuments
At the British Tomb of the Unknown Warrior in Westminster Abbey, or the American Tomb of the Unknown Soldier at Arlington, the visible daily ritual is a guard change: sentries perform precise drill movements while remaining mute, and the ceremony is essentially silent except for footwork and rifle drill. At the Arc de Triomphe there is no permanent sentry and no guard change. The Tomb is not under continuous armed watch — it is watched continuously by the flame itself, and renewed by the brief evening visit of a civilian or veterans' delegation rather than by a military rotation.
Practically this means three differences for visitors. First, the Arc ceremony is acoustic rather than visual — a bugle call, silence, and a national anthem carry the weight, where a guard change relies on drill movement. Second, the participants are civilian commemorators with military escort, not the on-duty military themselves: the symbolism is one of remembrance by the nation, not vigil by the army. Third, audience proximity is unusually close. There is no glass, no inner enclosure, and the cordon stands only a few metres from the slab. The vault concentrates the sound, so a quiet visitor near the back hears every note as clearly as a delegation at the front.
Etiquette, photography, and dates worth planning for
Etiquette is informal but firm. Stand still during Aux Morts and the Marseillaise. Remove hats. Do not cross the cordon under any circumstance, even after the ceremony ends — the cordon stays in place until the delegation has left the Place. Speak in a low voice or not at all from 18:25 onwards; the bugler begins almost the moment the delegation reaches the slab. Children are welcome and locals often bring them, but a fussy infant is more comfortably watched from the outer edge of the vault, where you can step back onto the pavement without disturbing the cordon. Service dogs are permitted; other dogs are not.
Three dates concentrate the ceremony's significance and bring substantial crowds. 8 May (V-E Day) opens with a presidential wreath-laying in the morning and a particularly large evening Ravivage. 11 November (Armistice Day) is the single most-attended evening of the year — the flame was first lit on this date in 1923, and the morning hosts the principal national commemoration. 14 July (Bastille Day) brings the military parade down the Champs-Élysées in the morning; the evening ceremony continues as usual but is preceded by extensive cleanup of the avenue. On all three dates the monument's paid climb is typically closed for the morning and reopens in the afternoon.
Frequently asked
What time is the eternal flame ceremony at the Arc de Triomphe?
Every evening at 18:30, year-round, without exception since 11 November 1923. The ceremony runs about ten minutes. Arrive by 18:15 to find a standing spot inside the vault.
Do I need a ticket to watch the 18:30 ceremony?
No. The Tomb of the Unknown Soldier sits beneath the central vault of the Arc, in a public memorial space. Watching the Ravivage de la Flamme is free and requires no booking — only the climb to the terrace requires a ticket.
Who relights the flame each evening?
A small delegation drawn from one of roughly 700 affiliated veterans' associations, regimental societies, and civic groups. The rotation is coordinated by the Comité de la Flamme. A different association officiates almost every night of the year.
When was the Tomb of the Unknown Soldier interred?
The coffin of the unidentified French soldier arrived at the Arc de Triomphe on 11 November 1920 and lay in state inside the monument. Final interment in the central vault took place on 28 January 1921.
Has the eternal flame ever gone out?
Not since the daily rekindling began in autumn 1923. The flame burned continuously through the German occupation of Paris (1940–1944), and the Ravivage was performed every evening of the occupation by French veterans' associations, in some cases under German surveillance.
Can I take photos during the ceremony?
Yes, without flash. The vault is dim and a wide-aperture lens or a steady hand is helpful. Flash photography is not permitted, nor is video lighting. Tripods inside the Place require a separate permit from the Centre des monuments nationaux.
How is this different from a changing-of-the-guard ceremony?
There is no permanent sentry at the Arc de Triomphe and no guard change. The ritual is acoustic — a bugler sounds Aux Morts, a minute of silence follows, and the Marseillaise plays — rather than the silent drill movements of British or American guard changes.
What does the inscription on the slab say?
Ici repose un soldat français mort pour la Patrie, 1914–1918 — 'Here rests a French soldier who died for the fatherland, 1914–1918.' The slab marks one unidentified casualty of the First World War, standing symbolically for every unnamed French dead.
Which evenings are busiest?
8 May (V-E Day), 14 July (Bastille Day) and especially 11 November (Armistice Day) draw the largest crowds, often several hundred attendees plus official delegations. Weekday evenings outside national commemoration dates usually draw 20 to 60 onlookers.
Where should I stand during the ceremony?
Inside the vault, outside the cordon, on either side of the slab. The cordon is set a few metres back from the tomb itself. The vault's acoustics carry the bugle and anthem clearly from any position; sightlines are best from the Champs-Élysées side of the slab.
