Historic Sanctuary of Machu Picchu

South America, Peru · Mixed (Cultural & Natural) site · UNESCO World Heritage property #274

Moderate ConcernConfidence: Supportedas of October 15, 2026

Significance

UNESCO describes Machu Picchu as an Inca city that stands at 2,430 m above sea level in tropical mountain forest on the eastern slopes of the Andes, known for its terraces, walls and ramps, within a biodiverse transition zone between the high Andes and the Amazon Basin. It is inscribed as a mixed property under cultural criteria (i) and (iii) and natural criteria (vii) and (ix).

Current Status Rationale

Historical damage and past disruptions (the 2004 debris flow, the January 2010 rains, the 2024 and 2025 rail blockades) are documented in the site's record, but the current classification is based on present conditions and the most recent credible evidence. The present picture, as of 15 October 2026 (the Committee and UNESCO wording below is paraphrased): the property is not on the Danger List; the Committee's most recent decision read (48 COM 7B.65, 2026) remains concerned that daily visitor numbers still exceed the 2015 carrying capacity study levels, says the conditions for increasing visitation are still not met, asks that the new carrying capacity study be submitted for review before final decisions, and asks for urgent mitigation planning for the Chinchero airport; it also welcomes progress on the 2026-2030 Master Plan and notes progress toward the Machu Picchu-Choquequirao Biosphere Reserve. Peru reports a Master Plan validated by the Machupicchu Management Unit, caps of 4,500 and 5,600 daily visitors and a rural-land-use committee. UNESCO's 2025 page lists landslide and flood risk among the issues for that cycle, and the Committee's 2023 decision refers to monitoring erosion and geological stability. Against this, the sources read show an actively functioning management and monitoring system, a Committee that has repeatedly asked for information rather than recommending danger listing, no documented unrepaired acute damage, and an access dispute (September 2025) that was reported as disruptive to visitors rather than damaging to the fabric. These are chronic, monitored threats rather than an acute emergency, which is what Moderate Concern describes. Confidence is Supported rather than Confirmed: the Committee decisions were read through a summarising tool, the 2026 Secretariat/Advisory Body assessment (WHC/26/48.COM/7B.Add) and UNESCO's 2026 state-of-conservation page were not read, Peru's own reports are not independent, the Chinchero airport timeline is unknown, 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 World Heritage Committee has repeated, across several sessions, concerns about pressures on the property other than natural hazards. Visitor numbers: in 2025 (47 COM 7B.57) the Committee was concerned that daily visitor numbers exceed the limits set by the 2015 carrying capacity study; in 2026 (48 COM 7B.65) it remained concerned, said the conditions for increasing visitation are still not met, and asked that the new carrying capacity study be submitted for review before final decisions on visitation. UNESCO's 2025 state-of-conservation page states that the daily cap is now 4,500 (5,600 in peak season), more than double the 2020 limit of 2,244, and reports the advisers' view that the absence of an independent technical review raises questions. Peru's Ministry of Culture set 2026 caps of 4,500 per day, rising to 5,600 on listed date ranges (including 19 June to 2 November) (El Peruano, 2 November 2025), and Peru's own January 2026 report describes the same 4,500/5,600 figures. Land use and development: in 2023 (45 COM 7B.100) the Committee noted reported increases in site invasion, looting and illegal land-use changes, especially along entrance routes; in 2025 it noted a new technical committee on rural land use (which UNESCO's 2025 page says was created by SERNANP and the district municipality) to address them; Peru's 2026 report says a Technical Committee led by the District Municipality is consolidating rural construction parameters to prevent unplanned growth. Infrastructure: in 2026 the Committee noted that the Heritage Impact Assessment for Chinchero International Airport (Cusco) identified significant impacts and requested an Action Plan with mitigation measures, to be submitted urgently and implemented before airport operations begin; the Visitor Centre Heritage Impact Assessment is reported by Peru as still pending. Governance: in 2025 the Committee was concerned about reported governance problems in the Machu Picchu Management Unit and the loss of site-level financial retention. Positive measures are also recorded: the Committee welcomed progress on the 2026-2030 Master Plan update (2026) and Law No. 31770 requiring Heritage Impact Assessments (2025). Access to the site has also been disrupted by disputes over transport arrangements (see events for September 2025); the sources read do not report damage to the heritage fabric from these disruptions. The Committee has not, in any decision read, recommended inscription on the Danger List.

First identified: Not established — Chronic, multi-year management concerns raised by the Committee across successive cycles (decisions read go back to 2021 in this dossier); no single start date established from the sources reviewed.

Natural Disaster

The property sits on steep, wet Andean slopes with documented landslide and flood exposure. UNESCO's 2025 state-of-conservation page lists avalanche/landslide and floods among the issues for the 2025 cycle (the Llaqta is the Inca citadel); it also states that earlier reports flagged the absence of a natural-disaster risk management plan, which is not among the threats it lists for 2025 (the plan's current status was not established in this pass). In 2023 (45 COM 7B.100) the Committee stated that admission limits should match the resources available for, among other things, monitoring erosion and geological stability on the Llaqta and its access routes. A 2005 conference abstract (Casagli and colleagues) assesses debris-flow and shallow-landslide hazard in the Machu Picchu area and refers to debris flows that damaged the access road in 1995-1996 and a channelized debris flow the day after Easter 2004 that, in the abstract's words, produced eleven casualties in nearby Aguas Calientes. In January 2010 heavy rains and landslides blocked the railway and stranded tourists; UNESCO reported on 28 January that the Citadel had not been impacted by the rainfall, and on 12 February described a planned emergency mission to address geological and geomorphological impacts on built heritage (see events). These hazards are chronic and monitored; the sources read do not document unrepaired damage from a recent event. The State Party's January 2026 report excerpt read does not address natural hazards.

First identified: Not established — Chronic natural exposure; no single start date applies. Earliest dated event in this dossier is the 1995-1996 road-damaging debris flows and the 2004 debris flow reported in a 2005 abstract (the abstract gives no precise dates beyond these).

    Landslides block railway; tourists stranded near Machu Picchu

    UNESCO reported on 28 January 2010 that on 25 January about 2,000 tourists were stranded after landslides blocked the railway between Aguas Calientes and Ollantaytambo, and that the Citadel had not been impacted by the heavy rainfall (while noting it is a small part of the protected area). NASA Earth Observatory reported about 4,000 tourists trapped for two days and that rail track and bridges were damaged, and also that the citadel was not damaged; the figures differ between the two sources.

    UNESCO plans emergency mission after the rains

    UNESCO reported on 12 February 2010 that its staff held a technical visit with Peruvian officials in Lima from 6 to 10 February and that an emergency mission with the Advisory Bodies and international experts was planned to address geological and geomorphological impacts on built heritage. It said it was concerned that the flooding had affected the water-carrying capacity of soils, which could cause future landslides and fatalities in the core zone.

Digital Preservation Index

Overall coverage: Extensive — Well documented across most or all digital preservation categories.

All five categories have publicly findable evidence, which reaches the extensive tier by the rubric (at least four, including a visual and a scholarly category). Evidence opened directly: UNESCO's photo gallery (12 images on the first page, about 42 in total by the 'See All' link, mixing site photographs and wildlife images), UNESCO's documents page, the University of Arkansas CAST page offering downloadable 3D laser-scan data, the 2005 conference abstract, and the Yale news story on the 2021 Antiquity study (the article itself was not opened). The virtual-tour category rests on news reports only: Peru's Ministry of Culture announcing a Google Street View agreement in 2015 (AFP via El Universo) and Andina in 2020 describing a Google Arts & Culture presentation; the Google pages themselves could not be opened, so the tours' current availability was not checked. The tier would still be extensive (four of five categories, including visual and scholarly) if the virtual-tour category were dropped. The CAST data licence is non-commercial, and its coverage of the whole sanctuary was not established.
