Moderate ConcernConfidence: Supportedas of October 15, 2026

Significance

Inscribed in 1991 under criteria (i), (ii) and (iv), the property covers the historic stretch of the Seine in Paris between the Pont de Sully and the Pont d'Iena, with the Ile de la Cite and Ile Saint-Louis. UNESCO describes the riverbanks as a view of the city's evolution and history, from the Louvre to the Eiffel Tower and from the Place de la Concorde to the Grand and Petit Palais, names Notre-Dame and the Sainte-Chapelle as architectural masterpieces, and credits Haussmann's wide squares and boulevards with influencing city planning worldwide.

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 fire of April 2019 belongs in the timeline; the present picture is of a reopened cathedral (December 2024) whose fire protection UNESCO's Advisory Bodies assessed positively in 2024 and 2025, a Committee that in 2025 commended the reopening and in 2026 welcomed completion of the second restoration phase and a Master Plan, an annual State of Conservation cycle with a next report due 1 February 2027, and no placement on the Danger List. Against that, real issues remain open: a multi-year restoration programme still to be completed and mostly unfunded according to press reports; a contested replacement of six historic windows that the Committee has asked France to suspend, which press reports say is going ahead after a Paris court judge declined to suspend the permit (the merits are pending); a Committee record of asking for impact assessments before irreversible decisions on several projects and regretting in 2025 that documentation for the cathedral-surroundings redevelopment came after authorisation; and an integrated management plan still being developed. Flooding is documented as exposure and past disruption (2016, February 2026) without reported damage to monuments. Together these are chronic, monitored threats rather than an acute emergency, which is what Moderate Concern describes. Confidence is Supported rather than Confirmed: the facts come from UNESCO decisions and state-of-conservation pages and are corroborated by independent reporting, but the 2026 state-of-conservation report itself (document 224588) could not be retrieved, the 2026 decision was read through a summarised rendering rather than verbatim, the outcome of the windows dispute is open, and the Moderate/High boundary is a judgment call. Confidence does not alter the status.

Conservation or other pressures are documented, but without imminent risk to the site. Credible sources support this status, with some limits on corroboration.

Threat Categories

Conservation / Structural

The 15 April 2019 fire at Notre-Dame is listed by UNESCO as a factor affecting the property, and 'fire' is the 'other threat' listed in the 2024 and 2025 state-of-conservation entries (the 2025 entry also lists 'impacts of visitor tourism and leisure activities'). The cathedral reopened in December 2024. The Committee's 2025 decision (47 COM 7B.105) commends the reopening, and its 2026 decision (48 COM 7B.35) welcomes the completion in 2025 of the second phase of restoration and the development of a Master Plan. Work is not finished: the restoration body's Master Plan page describes 11 operations between 2026 and 2031, while journalists report twelve phases running 2026-2033 and a programme costed at about 150 million euros, with about 20 million reported as secured (EWTN, July 2026) and about 130 million still to be raised (Finestre sull'Arte, July 2026). UNESCO's Advisory Bodies assessed the cathedral's fire-protection arrangements positively in both the 2024 and 2025 cycles (as summarised on the SOC pages). The main open conservation question in the Committee's record is the project to replace six 19th-century stained-glass windows in the south side of the cathedral with contemporary windows: in 2024 the Committee said the project should undergo a Heritage Impact Assessment, in 2025 it noted the project had advanced despite an unfavourable opinion from France's National Commission for Heritage and Architecture and asked for a 'thorough and independent' assessment, and in 2026 (48 COM 7B.35, as summarised from the decision text) it expressed concern that the assessment may rely on an interpretation of Outstanding Universal Value that does not fully recognise the cathedral as a key attribute and asked the State Party to suspend the project and reconsider replacing the historic windows. A Paris administrative court judge refused on 19 May 2026 to suspend the authorisation (urgency condition not met; the merits are reported as still pending), and press reports in July 2026 expect the new windows to be completed by the end of 2026. Beyond the cathedral, the Committee has repeatedly asked for impact assessments and early notification for projects across the property (Place de la Concorde, the cathedral surroundings on the Ile de la Cite, the Louvre 'Nouvelle Renaissance' project, a proposed National Assembly visitor centre) and regretted in 2025 that detailed documentation for the Ile de la Cite and cathedral-grounds redevelopment was not submitted before administrative authorisation. The 2022 joint mission noted the property had no overall management plan; in 2025 and 2026 the Committee welcomed/asked for work on an integrated management plan including a risk prevention plan. This is a monitored set of conservation and governance issues in an actively managed property, not an unresolved acute damage event.

First identified: April 15, 2019 — Date is that of the Notre-Dame fire, the earliest dated event in the sources reviewed for this category; development-review and management-plan concerns are ongoing and have no single start date.

Natural Disaster

The property lies along the Seine and is exposed to river flooding. In June 2016 Reuters reported the Seine reached about 6 metres in central Paris, its highest level in 30 years, with the Louvre and Musee d'Orsay closed and artworks moved to safety (the Reuters report notes the 1910 record of 8.6 metres was not approached); PBS NewsHour reported the river crested near 20 feet. In February 2026 Le Bonbon reported the Seine overflowing for several days, peaking at about 3.70 metres on 17 February (compared in the same article with about 6.10 m in 2016), with a list of quays, ports and tunnels closed to traffic and a deputy mayor calling it a controlled situation. None of the sources reviewed document structural damage to the property's monuments from the 2026 rise, and none of the UNESCO decisions or state-of-conservation entries read lists flooding as a factor affecting the property. This category therefore records documented exposure and past events, not a currently documented unrepaired disaster.

First identified: June 3, 2016 — Date is that of the June 2016 flood reported by Reuters; flood exposure itself is long-standing (the 1910 flood is referenced in the sources but is not separately documented here).

    Fire at Notre-Dame de Paris

    UNESCO's state-of-conservation entries and advisory-mission announcement record the fire at Notre-Dame on 15 April 2019 as a factor affecting the property. UNESCO's 2024 SOC entry describes the subsequent reconstruction work, including completion of the spire framework and installation of the cross and rooster in 2023, with reconstruction of the nave and choir roof structure under way.

    Joint World Heritage Centre / ICOMOS / ICCROM advisory mission to Notre-Dame

    A joint advisory mission visited on 28-29 March 2022, at France's invitation, to review the restoration and redevelopment programme. According to the mission report, the experts judged that rebuilding the roof framing and spire to their 1855-1864 state could restore the Outstanding Universal Value damaged by the fire, noted that fire-prevention studies were still in progress and that the property had no overall management plan, and recommended a restoration timeline, facade technical information and a risk prevention plan.

    Seine overflows in Paris, quays and ports closed

    Le Bonbon reported the Seine had been overflowing in Paris for several days and peaked at about 3.70 metres on 17 February 2026, with a list of quays, ports and tunnels closed to traffic; a deputy mayor was quoted calling it a controlled situation typical of winter, and the article attributes the rise to Storm Pedro and 35 consecutive rainy days reported by Meteo-France. Single-source; the article reports no damage to monuments.

    Notre-Dame Restoration Master Plan reportedly formalised

    Finestre sull'Arte reported that the conservation master plan was formalised in March 2026, with twelve phases running from 2026 to 2033. The restoration body's own Master Plan page describes 11 operations between 2026 and 2031. EWTN News (July 2026) reported a final phase running 2027-2033 and an investment of 150 million euros, of which about 20 million was reported as secured. Sources differ on the span and phase count; the March 2026 date rests on one source.

    Paris court declines to suspend replacement of Notre-Dame stained-glass windows

    Actu-Juridique reported that on 19 May 2026 the Paris administrative court's urgent-matters judge rejected a request by the associations Sites et Monuments and SOS Paris to suspend the prefectural authorisation to remove the Viollet-le-Duc windows and install windows by Claire Tabouret, finding the urgency condition not met (the article also reports the judge accepted the argument that the work is reversible). The article reports that a challenge on the merits and an appeal on the related contract remain pending, and that removal was scheduled to begin on 22 June with installation due in mid-October; Euronews (24 July 2026) reported the windows are expected to be installed by the end of 2026 and shown to the public in December. Whether removal has actually taken place was not confirmed.

    World Heritage Committee decision 48 COM 7B.35 on Paris, Banks of the Seine

    The Committee welcomed the completion in 2025 of the second phase of restoring Notre-Dame and the development of a Master Plan; and, as summarised from the decision text, expressed concern that the Heritage Impact Assessment for the stained-glass project may rely on an interpretation of Outstanding Universal Value that does not fully recognise the cathedral as a key attribute and asked the State Party to suspend the project and reconsider replacing the historic windows. It also noted the initiative to establish a Remarkable Heritage Site covering the property and its setting, asked for an integrated management plan including a risk prevention plan, asked for regular updates on the Place de la Concorde redevelopment, and for detailed information including impact assessments on the Louvre 'Nouvelle Renaissance' and proposed National Assembly visitor-centre projects, and requested an updated report by 1 February 2027. The decision text does not mention the Danger List; the property is not on UNESCO's Danger List page (src_01). The decision page read shows no month; July 2026 is inferred from the 48th session's timing as recorded in the HeritageWatch Venice dossier and should be confirmed.

Digital Preservation Index

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

Three of five categories are marked on evidence opened in this pass, which gives the moderate tier by the rubric (2-3 categories). Coverage is uneven and building-level: the 3D evidence concerns Notre-Dame only. Andrew Tallon's 2010 laser scan (reported at roughly one billion points) is the pre-fire record reported to have guided the restoration (GPS World, January 2025), but what is publicly viewable is limited: Geo Week News (May 2019) reported a public viewer with 41 scan positions that Leica's Michael Harvey described as only a subset, and said the full dataset was not described as publicly viewable. The viewer link itself could not be loaded in the research pass or the independent verification pass (access blocked both times), so its current availability rests on the Hexagon announcement (2019) and GPS World (2025); a reviewer should click it before accepting the 3D category. No whole-property 3D model was found. Not counted: a virtual tour of Notre-Dame (a fundraising charity's page describes a panorama tour hosted by Columbia University from the Mapping Gothic project; the tour itself was not opened), and academic scholarship (no peer-reviewed article could be opened in this pass; the Tallon-related and Mapping Gothic literature exists but was not verified). The tier therefore reflects what was verified, and may understate real coverage for a property this heavily studied.
