Conservation issues presented to the World Heritage Committee in 2018

On 31 January 2018, the State Party submitted a report on the state of conservation, which is available at http://whc.unesco.org/en/list/356/documents/, and outlines progress made in relation to the requests of the Committee, and in particular to various projects, as follows:

On 30 April 2018, the State Party submitted additional information including a finalized draft of the revised Management Plan, details of a proposed cultural HIA process, the revised structure of the Site Management Directorate as well as further details on the conservation strategies for protected examples of Ottoman structures. These documents outline following progress:

Further details of the strategy for the conservation of Ottoman timber and stone buildings will be shared with the World Heritage Centre and the Advisory Bodies.

Analysis and Conclusions of the World Heritage Centre, ICOMOS and ICCROM

The State Party has made visible efforts to streamline various reports on numerous projects in one coherent reporting approach and to respond to the Committee decisions in a proactive manner including through a close and regular dialogue with the World Heritage Centre and the Advisory Bodies.

However, the Committee noted in 2017 that the Yenikapi Tent was being constructed and that no HIA had been submitted. The structure has now been completed while the HIA remains to be finalized. Although the Committee requested full details to be provided for review of the already-approved Planetarium and Istanbul City museum projects, only visualizations and limited drawings have been submitted and no HIA. It is merely stated that no effect from the projects on the silhouette of the Land Walls was observed.

Details have been provided of planned infrastructure projects for new and extended metro lines and for a project, which has already started, to move a short section of a tramline underground.

The further revised draft of the Management Plan will be reviewed. It is still recommended that the Committee reiterate its request to determine the attributes that convey the OUV of the property as a matter of priority as these should form the basis for the Management Plan.

The planned workshop on Cultural HIAs is a positive step forward. The detailed information on the geo-radar measurements of the Chora Museum and the restoration of the Zeyrek mosque are welcomed.

The initiation of a project to document Ottoman timber and stone houses is welcomed as is the stabilisation work that is planned as part of this project. Such survey was first requested by the Committee in 1997 and in the meantime a significant proportion of these houses have deteriorated or been lost. No details of the timescale of the various phases of the project have been provided and what has been set out is not quite the emergency plan and long-term strategy for the Ottoman timber buildings that the Committee requested should be put in place by the end of January 2018. The amount of resources being directed at conservation projects remains impressive. Plans have been submitted for the reconstruction of the Hagia Sophia medrese for which an HIA had been prepared. Photographs and descriptive details of the analysis and work undertaken have been provided for the Land Walls, and also for the Bucoleon Palace, the Chora museum and the Molla Zeyrek mosque, although these do not encompass the methodology or justify the approach used.

Further to the 2016 Reactive Monitoring Mission Report, it is recommended that the Committee encourage the State Party to invite an advisory mission to review specifically the restoration and conservation projects, such as the Chora Museum, the Zeyrek Mosque and the Land Walls.

The overall report offers few new insights into conservation, renewal or new developments projects, apart from some infrastructure projects. A large number of renewal projects are still on-going for which no details have been provided that might provide assurances that these projects will not lead to loss of historic fabric.

It is recommended that the Committee reiterate its long-lasting concern that the situation remains highly delicate and strongly request the details of conservation and renewal projects or large-scale projects to be submitted in advance of decisions being taken and on the basis of appropriate HIAs.

It is finally recommended that the Committee urge the State Party to prepare a road-map including short and long-term strategies covering all types of projects (development/renovation/renewal), which may have an impact on the OUV of the property and determines all required details and steps in close cooperation with the World Heritage Centre and the Advisory Bodies before any irreversible decisions are taken.

Also notes the large number of proposed infrastructure and other projects, and recommends that the State Party develop a progress report on these, together with a road-map including short- and long-term strategies covering all types of projects (development/renovation/renewal) which may have an impact on the OUV of the property, and determine all required details and steps in close cooperation with the World Heritage Centre and the Advisory Bodies before any irreversible decisions are taken; and submit this road map to the World Heritage Centre by 1 February 2019;
  10. Encourages the State Party to invite an ICCROM/ICOMOS Advisory mission to review the restoration and conservation projects such as the Chora Museum and the Zeyrek Mosque in line with the recommendations of the 2016 Reactive Monitoring Mission report;
