Tomb of Askia

West Africa (Sahel), Mali · Cultural site · UNESCO World Heritage property #1139

High ConcernConfidence: Developingas of October 14, 2026

Significance

UNESCO describes the 17-metre pyramidal Tomb of Askia, built in 1495 by Askia Mohamed, Emperor of the Songhai Empire, in Gao. The complex also includes two flat-roofed mosques, a mosque cemetery and an open-air assembly ground, and reflects the wealth of an empire that controlled trans-Saharan trade in salt and gold. UNESCO calls it the most important and best-preserved remnant of the Songhai Empire and an example of Sudano-Sahelian earthen architecture, with plaster renewed regularly after the rainy seasons. It is inscribed under criteria (ii), (iii) and (iv).

Current Status Rationale

Historical damage is documented in the site's record, but the current classification is based on present conditions and the most recent credible evidence. Present conditions: the Committee retained the tomb on the Danger List in 2023, 2024, 2025 and again in 2026 (decision 48 COM 7A.39). The 2012 occupation, the closure of the Gao Cultural Mission and earlier structural collapses belong in events[] and do not by themselves drive the current status. What keeps the status at High is (i) formal Danger List status, with the Reinforced Monitoring Mechanism continuing (2023-2024 decisions); (ii) a security situation that the Committee called the main threat in 2024 and that, in 2026, includes reported fighting in Gao city (25 April and 4 July) within a wider offensive across northern Mali; and (iii) structural fragility and resourcing gaps that the 2026 decision still records (funding for the new plan and urgent works not secured; two of the 10 corrective measures not yet reported implemented). Against this, the evidence shows real progress: an ALIPH-funded rehabilitation (CRAterre reports all roofs redone, 6,500 bricks used and 120 wooden beams replaced for the 2020-2025 project), a buffer-zone resettlement solution, an updated 2026-2030 management plan, and a Committee that in 2026 recorded significant progress and adopted the Desired State of Conservation for Removal. No source read reports damage to the tomb from the 2026 fighting. Confidence is Developing rather than Supported: the Committee decisions are primary and consistent, but the State Party's 2026 state of conservation report and the Secretariat's assessment could not be read, accounts of who controlled Gao in April 2026 conflict, no Gao-specific security reporting after 18 July 2026 was found, and the tomb's current physical condition after April 2026 is not independently documented. The High/Critical boundary is a judgment call. Confidence does not alter the status.

Serious, currently active threats are documented, or major historical damage remains substantially unrepaired. The situation is actively changing and evidence is still emerging.

Threat Categories

Armed Conflict

UNESCO's 2012 state of conservation summary states that fighting in northern Mali left Gao under rebel and Islamist control from early April 2012 and that the Gao Cultural Mission, which manages the property, was closed; the Committee placed the property on the List of World Heritage in Danger on 28 June 2012 at Mali's request (the 2015 summary gives the occupation as March 2012 to January 2013). UNESCO's 2015 summary states the tomb was not physically damaged during the occupation but was not maintained or replastered, so cracks and holes appeared, and a 2014 UNESCO news item reports that young people in Gao defended the site. Insecurity is flagged in the 2016, 2024 and 2026 Committee decisions reviewed: in 2016 the Committee expressed concern about the unstable security situation at Gao, which prevented Mali from inviting a monitoring mission, and in 2024 it stated that 'insecurity continues to be the main threat to the property'. In 2026 the Committee's decision still asks Mali to invite a joint UNESCO/ICOMOS/ICCROM reactive monitoring mission only 'if security conditions permit'. AFP reported in September 2024 that rebels had been driven from the towns but the region still suffers violence and that foreign experts no longer visit. In 2026 fighting reached Gao: AP reported on 25 April 2026, citing a resident, gunfire and explosions in Gao as a coordinated offensive began, and a separatist spokesperson claimed control of some areas of Gao (which AP could not verify); the Long War Journal (26 April) described Gao as 'only partially under the control' of the JNIM-FLA force with Malian and Russian troops in former UN positions in the city, while the Critical Threats Project (28 April) said JNIM and the FLA had seized Gao. These accounts differ and the sources reviewed do not settle who held the city in late April. Al Jazeera reported that on 4 July 2026 a military camp in Gao was attacked and that the army said six 'terrorists' were killed in Gao, and on 18 July 2026 an army convoy was ambushed near Tabankort in the Gao region. None of the sources reviewed reports damage to the tomb from this fighting, or places the fighting at the property.

First identified: Not established — Gao came under rebel and Islamist control from early April 2012 according to UNESCO's 2012 state of conservation summary; the exact day is not given in the sources reviewed.

Conservation / Structural

The earthen structure has a documented history of structural weakness. UNESCO's 2012 summary records the collapse of pillars at the Women's Tomb in 2011; the 2015 summary records pillar collapses in 2006, 2011 and 2013 and says wooden pillars and roof had weakened with age and with the weight of mud layers from annual plastering. A CRAterre conservation manual (read via an Internet Archive copy) lists roof collapses in 2006, 2011, 2017 and 2024. AFP reported that in mid-August 2024 part of the men's mosque ceiling collapsed during heavy rain while a pillar was being repaired. The Danger List inscription rests on the occupation of Gao by armed groups, inability to ensure daily management, and risk of collapse (UNESCO 2023 and 2024 summaries). The Committee has since tracked an ALIPH-funded rehabilitation project (structural consolidation, staff training, fencing, a conservation manual) and 10 corrective measures adopted in 2016. Its 2026 decision records significant progress in the conservation of the property, records that eight of the 10 corrective measures have been implemented, records an updated Management and Conservation Plan for 2026-2030, and notes that funding sources for the new plan and budget allocations for urgent conservation work are still lacking. Illegal housing in parts of the buffer zone was also a concern (2024 summary); the 2026 decision records a resettlement solution for buffer-zone occupants with two residential plots made available. Lack of funding for the Gao Cultural Mission was raised in 2025. The tomb's own earlier condition at inscription was rated good by ICOMOS in 2004, with development eroding the traditional urban setting identified as the greatest threat.

First identified: Not established — Chronic structural weakness with dated collapses (2006, 2011, 2013, 2017, 2024 per the sources above) and management concerns over successive reporting cycles; no single start date.

Environmental / Climate

Rain and weather are documented as ongoing pressures on the earthen fabric. UNESCO's 2024 summary reports water erosion in the prayer area (being countered with fine sand) among maintenance concerns that the World Heritage Centre considers non-major, and the 2016 corrective measures include control of silting, drainage and rainwater erosion at the necropolis. The CRAterre manual lists degradation factors including rain and wind, climate change, termites and bats. UNESCO's 2014 news item said the tomb needed urgent safeguarding before the June rainy season. AFP reported in September 2024 that the August 2024 ceiling collapse happened during heavy rains and quoted the regional agency Agrhymet as saying Sahel rainfall in recent weeks was 120% to 600% above the 1991-2020 average (a regional figure, not specific to Gao); it also cited a 2022 study that an event once expected about one year in ten now occurs about one year in five. These are chronic, managed pressures; the sources reviewed do not document a distinct climate-related emergency at the property.

First identified: Not established — Chronic pressure from rainfall and weathering on an earthen monument that requires regular replastering; no single start date established.

    Gao comes under rebel and Islamist control

    UNESCO's 2012 state of conservation summary states that fighting in northern Mali left Gao under rebel and Islamist control from early April 2012 and that the Gao Cultural Mission, which manages the property, was closed, so daily protection and conservation could not be carried out. UNESCO's 2015 summary gives the occupation as March 2012 to January 2013.

    Committee places the Tomb of Askia on the List of World Heritage in Danger

    UNESCO reported that the World Heritage Committee accepted Mali's request to place the Tomb of Askia, along with Timbuktu, on the Danger List to increase cooperation and support for sites threatened by armed conflict. The 2012 state of conservation summary (decision 36 COM 7B.106) records that the Committee found the conditions for preservation no longer existed and that the property faced a specific, proven, imminent danger. The property has remained on the List since.

    First UNESCO assessment mission to Gao since the occupation

    A UNESCO news item dated 13 February 2014 reported that UNESCO, Malian and international experts completed the first damage assessment of Gao's cultural heritage. It reported that the Tomb of Askia needed urgent safeguarding before the June rainy season, that residents had already repaired parts of the earthen monument, and that young people in Gao defended the site during the occupation, sparing it the kind of damage inflicted on World Heritage sites in Timbuktu.

  8. 2016
    Committee adopts 10 corrective measures (decision 40 COM 7A.7)

    The Committee adopted 10 corrective measures in two groups (physical components, and protection and management), asked Mali to complete a proposed Desired State of Conservation for removal, and expressed concern about the unstable security situation at Gao, which prevented the State Party from inviting a monitoring mission. A joint UNESCO/ICOMOS/ICCROM reactive monitoring mission was requested once the situation in northern Mali is stabilised.

  9. 2020
    ALIPH-funded rehabilitation project begins

    The Committee's 2024 decision refers to the project as having begun in January 2020, while UNESCO's 2023 summary of the State Party report gives 10 March 2020; sources differ on the exact date. CRAterre lists the project as 2020-2025, first planned for 2020-2022 and extended because of constraints including Covid and security. ALIPH's page describes a full rehabilitation project to stop further deterioration and collapse.

    Part of the men's mosque ceiling collapses during heavy rain

    AFP reported that in mid-August 2024, during heavy rains, part of the men's mosque ceiling collapsed while a pillar was being repaired; an architect working on the restoration said the structure is weakened and the wood very old, and that work would likely resume around late September. The CRAterre manual also lists a roof collapse in 2024.

    Coordinated offensive reaches Gao

    AP reported gunfire and explosions in Gao from early that Saturday, citing a resident who said the gunfire came from the army camp and the airport, and a separatist spokesperson's claim of control of some areas of Gao, which AP could not verify. The Long War Journal (26 April) described Gao as only partially under the control of the JNIM-FLA force with Malian and Russian troops in former UN positions, while the Critical Threats Project (28 April) said JNIM and the FLA had seized Gao. These accounts differ. None of them reports damage to the Tomb of Askia.

Digital Preservation Index

Overall coverage: Moderate — Documented in several categories, with some notable gaps.

Two of five categories have publicly findable evidence, which gives the moderate tier by the rubric. Photographic coverage is a UNESCO-hosted gallery (at least 12 images on its first page; the total was not established) credited mainly to the OUR PLACE collection, CRAterre and a UN mission, plus a CRAterre project photo gallery. Archival records are official documentary records rather than a digitised archive: the 2003 nomination file and the 2004 ICOMOS evaluation (both public PDFs on UNESCO's site) and a roughly 52-page CRAterre conservation manual with survey drawings (read via an Internet Archive copy). UNESCO state of conservation reports are deliberately not counted. No 3D model, laser scan or photogrammetry was found. A Google Arts & Culture page exists but is a text story, not a virtual tour or Street View. No peer-reviewed study was found in this pass (an ACLS 2025 grant page describes a forthcoming monograph, which is not published scholarship), so academic_scholarly is marked false; a reviewer who knows of published studies may change this, which would not alter the moderate tier unless it brought the count to four. Reflects what is publicly findable, not necessarily what exists in unpublished archives.
