Guinness World Records lists Wadi al-Salam in Najaf, Iraq, as the world’s largest cemetery. It covers about 3.54 square miles (9.17 square kilometers) and contains the remains of millions of people. The exact burial total is unknown, but the cemetery has been used continuously for more than 1,400 years and remains active today.
How to use this article: Looking for one detail? Check the measured area, why burial totals vary, why Shia Muslims seek burial here, or what its UNESCO status means.
Size and Burial Count
Guinness World Records identifies Wadi al-Salam as the largest burial ground in the world and gives its area as 3.54 square miles (9.17 square kilometers). Iraq’s submission to the UNESCO World Heritage Centre gives the equivalent measurement of 917 hectares. This is the basis for calling it the world’s largest cemetery, or largest graveyard.
How much land does the cemetery cover?
Those figures equal about 2,266 acres (917 hectares). A smaller measurement of 1,485.5 acres appears in many summaries, but it conflicts with both Guinness and Iraq’s heritage submission. The 3.54-square-mile (9.17-square-kilometer) figure is therefore the more reliable measurement for the full cemetery.
How many people are buried there?
The often-repeated figure of more than six million burials is an estimate, not a counted total. A UNESCO publication gives a figure of at least five million, while Guinness says the cemetery contains “millions of sets of human remains.” Neither source presents a complete burial register.
Many underground rooms and family crypts contain more than one person, sometimes from several generations. The number of visible grave markers therefore cannot be converted directly into the number of people buried at Wadi al-Salam.

Historical Backdrop
Wadi al-Salam has been used continuously since at least the seventh century. The cemetery grew with Najaf through successive dynasties, the formation of modern Iraq, wars, and periods of political upheaval.
More than 1,400 years of burials
Guinness dates the cemetery’s continuous use to the seventh century. Wadi al-Salam was not planned and filled in one period; it expanded over generations while people continued to bury their dead there.
That gradual growth left tombs from different periods side by side. Older mausoleums stand near later family vaults, and new funerals still take place within a cemetery already shaped by more than fourteen centuries of burial.
Claims of earlier burial traditions
Iraq’s UNESCO Tentative List submission connects burial in the area with periods before the Islamic Middle Ages and mentions rulers associated with the Sassanian era. UNESCO’s study of Najaf also places the cemetery within a longer Mesopotamian tradition of burial grounds accumulating beside settlements.
These references point to an older burial tradition around Najaf, but they do not prove that the whole present-day cemetery was used continuously before Islam. Its continuous use as a major Islamic cemetery is documented from the seventh century.
Religious Significance
The cemetery’s location beside the Imam Ali Shrine is the main reason it grew so large. The shrine is traditionally believed to contain the tomb of Ali ibn Abi Talib, the fourth caliph and the first imam in Shia Islam. Najaf consequently became a major center of Shia pilgrimage, learning, and burial.
Why Shia Muslims seek burial here
Shia traditions associate burial near Imam Ali with intercession, spiritual protection, and closeness to a sacred figure. The Imam Ali Holy Shrine also records beliefs connecting Wadi al-Salam with the souls of believers and the religious merit of burial in Najaf. These are religious beliefs rather than historical claims, but they explain why families have sought burial here for generations.
Burials are not limited to residents of Najaf. Families from elsewhere in Iraq, Iran, and other countries have brought their dead to Wadi al-Salam, making it a burial place of international importance within Shia Islam.
The connection to the Imam Ali Shrine
The shrine and cemetery are closely connected, but they are not the same site. Guinness notes that funeral prayers are conducted at the Imam Ali Mosque before burial in Wadi al-Salam. The link between the funeral rites and the shrine has sustained demand for nearby burial space for centuries.
Layout & Architecture
Wadi al-Salam does not resemble a cemetery organized into uniform lawns and straight rows. Its dense burial landscape includes simple grave markers, raised tombs, domed mausoleums, underground vaults, and structures reserved for individual families.
Tombs, vaults, and family rooms
Iraq’s heritage submission describes low graves, taller tomb structures, family burial rooms, and underground vaults reached by ladders. It also notes the use of baked brick and plaster. Guinness reports that some crypts, mausoleums, and catacombs can contain as many as 50 sets of human remains.
This is why the number of monuments above ground is much lower than the estimated number of burials. One family room or underground vault may contain several generations.
Why the cemetery can look like a city
Closely packed structures rise at different heights, with narrow paths passing between them instead of broad lawns or uniform rows. From a distance, the domes and walls can resemble a low-built city. The irregular layout developed as the cemetery expanded and new burials were added among older structures.
Conflict and Modern History
Despite its peaceful name, Wadi al-Salam became part of the battlefield during periods of conflict in Najaf. Its dense tombs, walls, and underground spaces provided cover and made movement through the cemetery difficult.
The 2004 Battle of Najaf
During fighting in 2004, members of Muqtada al-Sadr’s Mahdi Army used the cemetery’s tombs and catacombs for cover while confronting U.S. and Iraqi forces. A U.S. Marine Corps history of the battle describes the closely spaced burial structures as difficult terrain for combat, and Guinness records that tombs were damaged by gunfire, mortars, and rockets.
The fighting damaged a sacred site that normally functions as an active burial ground and destination for pilgrims. Wadi al-Salam continued to be used for burials and pilgrimage after the battle.
War also changed the pace of burial
Guinness reports that, at the height of the Iraq War, as many as 250 bodies were interred in one day. This was an exceptional wartime rate, not a normal measure of daily burials.
UNESCO Tentative List Status
Iraq added Wadi al-Salam to its UNESCO Tentative List on January 24, 2011, under proposed cultural criteria (iii), (v), and (vi). This placed the cemetery in Iraq’s inventory of sites it may seek to nominate, but it did not make Wadi al-Salam a World Heritage Site.
What Tentative List status means
A Tentative List is a national inventory of places a country may consider nominating in the future. It is a preliminary step, not inscription on the World Heritage List. The UNESCO World Heritage Centre’s Iraq page still places Wadi al-Salam among Iraq’s tentative properties rather than its inscribed World Heritage Sites.
Why Iraq proposed the cemetery
Iraq’s submission points to the cemetery’s scale, continuous use, burial architecture, and connection with living religious beliefs. These are the qualities on which a possible future nomination would be based.
The wording on the Tentative List page comes from the submitting country, which remains responsible for it. UNESCO’s publication of the entry confirms Iraq’s interest in a future nomination, not a final UNESCO judgment on the cemetery.
Frequently Asked Questions
Is Wadi al-Salam really the largest cemetery in the world?
Yes. Guinness World Records recognizes Wadi al-Salam as the largest burial ground, with an area of about 3.54 square miles (9.17 square kilometers).
Are more than six million people buried there?
More than six million is a widely repeated estimate, not a verified census total. Authoritative references use figures ranging from at least five million to the broader description “millions,” so the exact number should not be treated as settled.
Is Wadi al-Salam still used for burials?
Yes. It remains an active cemetery after more than 1,400 years of continuous use, with new interments taking place alongside older tombs and family vaults.
Is Wadi al-Salam a UNESCO World Heritage Site?
No. It has been on Iraq’s UNESCO Tentative List since 2011, but it has not been inscribed on the World Heritage List.
Can tourists visit Wadi al-Salam?
The cemetery receives visitors and pilgrims, but it is an active sacred burial ground rather than a conventional attraction. Access arrangements, photography rules, and local conditions should be confirmed before any visit. The U.S. Department of State currently advises U.S. citizens not to travel to Iraq because of serious security risks.
What Did We Learn Today?
Guinness World Records lists Wadi al-Salam as the world’s largest cemetery, covering about 3.54 square miles (9.17 square kilometers). Its millions of burials accumulated through more than 1,400 years of continuous use, sustained by Najaf’s importance in Shia Islam and the desire to be buried near Imam Ali. The cemetery is on Iraq’s UNESCO Tentative List, but it is not a World Heritage Site.
Sources & Data Notes
Area and record status were checked against Guinness World Records; history, burial forms, and heritage status against UNESCO’s Najaf publications and the World Heritage Centre’s Tentative List record submitted by Iraq; religious context against the Imam Ali Holy Shrine; conflict history against a U.S. Marine Corps account; and current U.S. travel advice against the U.S. Department of State. Burial totals are estimates rather than a verified census, so the article uses “millions” as its main figure. This article was prepared and editorially reviewed Z.K.
