When a pope dies or steps down, the Catholic Church enters sede vacante—Latin for “the seat being vacant.” During this rare and sacred period, the world turns its attention to the Conclave: the centuries-old, secretive ritual held in the Sistine Chapel to elect a new pope. Steeped in symbolism and global significance, the Conclave remains one of the Vatican’s most solemn traditions.

What is the Conclave?

The word conclave comes from the Latin cum clave—“with a key”—referencing the practice of locking the cardinals in a secure space until a new pope is chosen. Today, that space is the Sistine Chapel.

Only cardinals under the age of 80 are eligible to vote. They gather in strict isolation, cut off from the outside world—no phones, no internet, no media. Even the staff attending to them are sworn to secrecy.

🕯 The ritual & the rules

Secrecy is absolute: No communication is allowed with anyone outside the Chapel. The cardinals even take an oath of secrecy before the first ballot.
Votes are cast by paper ballot: Each cardinal writes the name of his choice and places it on a specially designed altar.
Four rounds of voting occur each day: Two in the morning and two in the afternoon.
A two-thirds majority is required to elect the new pope.

After each voting session, the ballots are burned:

Black smoke (fumata nera) indicates no decision has been reached.
White smoke (fumata bianca) signals the election of a new pope.

The moment the smoke turns white, the world watches as history unfolds. The process can last from a day to several weeks.

Typically, the conclave lasts 2–4 days, but it can take longer depending on how quickly a consensus is reached. The Sistine Chapel may remain closed for a total of 4 to 6 weeks, including setup and post-election protocols.

Why it matters?

Though inaccessible during this time, the Sistine Chapel is at the heart of a moment that defines the future of the Catholic Church. The conclave connects modern governance with ancient ritual, and its outcome is watched by millions around the world.

If you're in Rome during the conclave, you won't get into the chapel—but you can witness history unfold in real time in St. Peter’s Square.

How to see the Conclave from outside the Chapel?

While the Sistine Chapel is closed to visitors during the Conclave, you can still be part of this historic moment—from the square outside. Here’s where to go, what to expect, and how to make the most of it.

📍 St. Peter’s Square – Waiting for white smoke

Why it matters: This is where the world learns a new pope has been chosen. When the cardinals reach a decision, white smoke rises from the Sistine Chapel chimney and bells ring throughout the Vatican.

When to arrive: If the Conclave is in progress, try to be in the square each day just before sunset—that’s when voting rounds typically conclude. Also, the Basilica may still host services or have limited access during this period. If it's open, aim for visits after 3pm.

What to bring: The exact time of the white smoke can vary, and the announcement may come hours later. Be prepared for a wait:

Water & snacks (there’s no seating)
Layers or an umbrella, depending on the weather
A portable charger for your phone or camera
A candle or small token of reflection, if you’d like

Tip: Follow Vatican News and Rome-based reporters on Twitter or Telegram. White smoke can happen at any time, and these channels often announce signs of movement.

How to behave

Respecting the solemnity of the Conclave and the sacred spaces of the Vatican is paramount.

Dress code

General guidelines: Both men and women should ensure their shoulders and knees are covered. Avoid sleeveless tops, shorts, miniskirts, and low-cut clothing.
Footwear: Comfortable walking shoes are recommended. Open-toed sandals and flip-flops are discouraged.
Headwear: Men should remove hats upon entering sacred areas. Women may wear hats, especially during outdoor events.

Behavioral etiquette

During ceremonies and announcements, keep conversations to a minimum and speak in hushed tones.
Refrain from using flash photography. In some areas or during specific events, photography may be prohibited altogether.
Set phones to silent mode. Avoid taking calls or using devices during ceremonies.
Follow instructions from security personnel and respect cordoned-off areas.

Best spots to watch the white smoke and the new Pope’s first appearance

St. Peter’s Square — Near the Central Obelisk

Why: This is the heart of the square and offers a direct, unobstructed view of both the Sistine Chapel chimney (where the smoke appears) and the central balcony of St. Peter’s Basilica (where the new pope is announced).
Tip: Arrive several hours early to secure a good position, as this spot fills quickly.

The steps and raised platforms around the Square

Why: Elevated positions along the steps and platforms provide better sightlines over the crowd and clearer views of the papal balcony.
Tip: If you can find a spot on the wide staircase leading to the basilica or near the colonnades, you’ll have a great vantage point.

Via della Conciliazione

Main avenue leading to the Vatican

Why: This broad avenue offers views of the square from a distance, allowing more space to move and easier exit routes.
Tip: Best for those who want to avoid the densest crowds but still witness the historic moment.

Rooftop terraces & nearby cafés

Private access or booked in advance

Why: Some hotels, restaurants, or private venues offer terraces overlooking St. Peter’s Square. These spots provide a comfortable, less crowded experience to see the announcement and smoke.
Tip: These options require advance booking and can be costly but offer a premium viewing experience.
