Old Walled City of Shibam

Significance

UNESCO describes Shibam as a 16th-century walled city and one of the oldest and best examples of urban planning based on vertical construction, with sun-dried mud-brick tower houses of up to seven storeys rising from the edge of Wadi Hadramaut, earning the nickname 'the Manhattan of the desert'. It stood at a caravan halt on the spice and incense route and replaced an earlier settlement partly destroyed by a flood in 1532-3. It is inscribed under cultural criteria (iii), (iv) and (v).

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. The 2008 flood and the reported 2020 flood damage are recorded in the timeline. The present picture, per the Committee's 2026 decision, is a property still on the Danger List and still described as vulnerable to the conflict, climate change and development pressures, with an outdated Conservation Plan, open questions on a Governmental Complex and a proposed asphalt road, and a request for a heritage impact assessment before works. Against that, the evidence shows real, funded repair work (EU-funded project phases commended in 2024, 2025 and 2026; ALIPH's USD 1,568,977 project for 2025-2027 covering up to 63 houses and three public buildings; 18 buildings restored under an earlier ALIPH partnership; the national authority's own report of 35 mud buildings restored in 2020-2021), a Committee that commends progress, and no documented fighting at the city. The Committee has also asked for work toward a Desired state of conservation for removal from the Danger List, which signals a process but not an imminent outcome. The main uncertainty is that the State of Conservation reports for 2023-2026 could not be read (UNESCO's pages returned a bot-check), no international monitoring mission has been possible, and the numbers of damaged and repaired buildings are unclear, so the present condition rests on Committee decisions, project descriptions and the State Party authority's own report. Confidence is Supported rather than Confirmed because the Danger List status and the Committee's concerns are corroborated by primary UNESCO decisions, but the scale of current physical damage is not independently verified. Confidence does not alter the status.

Serious, currently active threats are documented, or major historical damage remains substantially unrepaired. Credible sources support this status, with some limits on corroboration.

   Disastrous flood affects the city

   Property placed on the List of World Heritage in Danger

   At its 39th session the Committee decided (39 COM 7B.60) to inscribe the property on the Danger List, noting great concern at significant threats from natural elements, physical changes and a lack of organisational support and resources for conservation. UNESCO's announcement said the Committee considered the site under potential threat from armed conflict and that listing could help reinforce international mobilisation.

   UNESCO statement on loss of life and property after extreme weather

   UNESCO said it profoundly regretted loss of life and property in historic centres in Yemen, including Zabid, Shibam and Sana'a, after exceptional extreme weather, and said it was mobilising funds and expertise, including an EU-funded cash-for-work project covering Aden, Sana'a, Shibam and Zabid. The statement does not give Shibam-specific damage figures.

   Floods reportedly destroy towers and damage others

   The New Arab, drawing on AFP and agency reporting, quoted a local official as saying at least four towers were completely destroyed and 15 others damaged in recent floods, and the head of the national historic-cities authority as saying roofs and exteriors suffered most and residents could not restore them because of the war. The report says restoration of about 40 buildings costing $194,000 was under way with UNESCO. Figures are one official's account.

   Emergency restoration of 18 damaged historic buildings reviewed on site

   The Regional Centre for the Protection of World Heritage in the Arab Region reported a visit assessing completion of a first partnership project with ALIPH and GOPHCY-Shibam, which funded emergency restoration of 18 damaged historic buildings by local associations using traditional techniques, including replastering and filling cracks to keep water out. A second ALIPH partnership, on rehabilitating the Old Market, was starting.

Digital Preservation Index

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

Two of five categories have publicly findable evidence, which meets the moderate tier. The photographic evidence is a UNESCO gallery (two pages, with images credited to UNESCO, Editions Gelbart and an individual photographer), so it is institutional rather than a systematic survey. The archival evidence is UNESCO's documents page (Committee decisions from 1982 and State of Conservation reports and index pages from 1991 (State Party reports from 2015), plus the 1982 ICOMOS evaluation and mission reports of 1997 and 2009) and the GOPHCY Shibam branch's 2021 report (a separate UNESCO-hosted document); UNESCO's property page also states that GOPHCY documented 98% of the traditional housing, but that documentation itself was not found online. 3D documentation is marked false: GOPHCY's 2021 report says a 3D documentation project of at-risk monuments in Wadi Hadhramaut, funded by ALIPH and supervised by Iconem, ran from October 2020 to August 2021, but no publicly viewable Shibam model was found, and the CEFAS/Iconem project page read did not name Shibam. No virtual tour was found. No peer-reviewed study of Shibam was read; a 2014 short article by Rita Cofield (California Preservation Foundation) was found but is a professional-association piece and is not counted. A reviewer may wish to note that the existence of unseen records (the housing documentation and the Iconem work) could mean the public record understates what exists.

• Photographic

  UNESCO World Heritage Centre hosts a public photo gallery for the property (two pages), credited to UNESCO, Editions Gelbart and a named photographer.

• Archival Records

  UNESCO's documents page for the property lists Committee decisions (1982 to 2026) and State of Conservation reports (State Party reports 2015 to 2026; index pages 1991 to 2026), the 1982 ICOMOS evaluation and mission reports (1997, 2009). The Shibam branch of GOPHCY's 2020-2021 state report is hosted on UNESCO's site as a separate document (whc.unesco.org/document/191652) but was not listed on the documents page read.

• Three D Documentation

  NOT COUNTED toward the tier: GOPHCY's 2021 report says an ALIPH-funded, Iconem-supervised 3D documentation project of at-risk monuments in Wadi Hadhramaut ran from October 2020 to August 2021, but no publicly viewable Shibam model was found.
