Vienna Memorandum
The following document presents the Memorandum adopted by the International
Conference on “World Heritage and Contemporary Architecture – Managing theHistoric Urban Landscape” as it was presented to the 29th session of the World
Heritage Committee (Durban, 2005) (see Document WHC-05/29.COM/5):
VIENNA MEMORANDUM
on“World Heritage and Contemporary Architecture –Managing the Historic Urban Landscape”

A.

PREAMBLE
1. Recalling that the Vienna Memorandum is the result of an international
conference on the subject of “World Heritage and Contemporary Architecture”,
which was requested by the World Heritage Committee at its 27th session(UNESCO, 2003) (Decision 27 COM 7B.108) and held from 12 to 14 May 2005
in Vienna, Austria, under the patronage of UNESCO and attended by more than
600 experts and professionals from 55 countries;
2. Bearing in mind the scope of UNESCO’s Convention concerning the Protectionof the World Cultural and Natural Heritage (World Heritage Convention, 1972),
and recalling its Articles 4 and 5, striving for global collaboration and the need for
global discussions on the subject of the strong economic dynamic and recent
structural changes in cities inscribed on UNESCO’s World Heritage List;
3. Further recalling that sites are inscribed on the World Heritage List on the basis of
the Statement of Outstanding Universal Value and that the preservation of thisvalue should be at the centre of any conservation policy and management
strategy;
4. Considering in particular the 1964 “International Charter for the Conservation andRestoration of Monuments and Sites” (Venice Charter), the 1968 “UNESCO
Recommendation concerning the Preservation of Cultural Property endangered by
Public or Private works”, the 1976 “UNESCO Recommendation concerning theSafeguarding and Contemporary Role of Historic Areas”, the 1982 ICOMOSIFLA “International Charter for Historic Gardens” (Florence Charter), the 1987
ICOMOS “Charter for the Conservation of Historic Towns and Urban Areas”(Washington Charter), the 1994 Nara Document on Authenticity, as well as theVienna Memorandum and Decision 29 COM 5D

WHC-05/15.GA/INF.7, p. 1

HABITAT II Conference and Agenda 21, which was ratified by Member States in
Istanbul (Turkey) in June 1996;
5. Desiring that the Vienna Memorandum be seen, within the continuum of these
afore-mentioned documents and the current debate on the sustainable
conservation of monuments and sites, as a key statement for an integrated
approach linking contemporary architecture, sustainable urban development andlandscape integrity based on existing historic patterns, building stock and context.
B.

DEFINITIONS
6. The present Memorandum refers to historic cities already inscribed or proposed
for inscription on the UNESCO World Heritage List, as well as to larger cities
that have World Heritage monuments and sites within their urban territories.
7. The historic urban landscape, building on the 1976 “UNESCO Recommendation
concerning the Safeguarding and Contemporary Role of Historic Areas”, refers toensembles of any group of buildings, structures and open spaces, in their naturaland ecological context, including archaeological and palaeontological sites,
constituting human settlements in an urban environment over a relevant period oftime, the cohesion and value of which are recognized from the archaeological,architectural, prehistoric, historic, scientific, aesthetic, socio-cultural or ecologicalpoint of view. This landscape has shaped modern society and has great value forour understanding of how we live today.
8. The historic urban landscape is embedded with current and past social expressions
and developments that are place-based. It is composed of character-defining
elements that include land uses and patterns, spatial organization, visualrelationships, topography and soils, vegetation, and all elements of the technicalinfrastructure, including small scale objects and details of construction (curbs,paving, drain gutters, lights, etc.).
9. Contemporary architecture in the given context is understood to refer to all
significant planned and designed interventions in the built historic environment,
including open spaces, new constructions, additions to or extensions of historicbuildings and sites, and conversions.
10. The expanding notion of cultural heritage in particular over the last decade, which
includes a broader interpretation leading to recognition of human coexistence withthe land and human beings in society, requires new approaches to andmethodologies for urban conservation and development in a territorial context.
The international charters and recommendations have not yet fully integrated thisevolution.
11. The Vienna Memorandum focuses on the impact of contemporary development on
the overall urban landscape of heritage significance, whereby the notion ofVienna Memorandum and Decision 29 COM 5D

WHC-05/15.GA/INF.7, p. 2

historic urban landscape goes beyond traditional terms of “historic centres”,“ensembles” or “surroundings”, often used in charters and protection laws, toinclude the broader territorial and landscape context.
12. The historic urban landscape acquires its exceptional and universal significancefrom a gradual evolutionary, as well as planned territorial development over a
relevant period of time through processes of urbanization, incorporating
environmental and topographic conditions and expressing economic and sociocultural values pertaining to societies. As such, protection and conservation of thehistoric urban landscape comprises the individual monuments to be found inprotection registers, as well as ensembles and their significant connections,physical, functional and visual, material and associative, with the historictypologies and morphologies.
C.

PRINCIPLES and AIMS
13. Continuous changes in functional use, social structure, political context andeconomic development that manifest themselves in the form of structuralinterventions in the inherited historic urban landscape may be acknowledged aspart of the city's tradition, and require a vision on the city as a whole withforward-looking action on the part of decision-makers, and a dialogue with theother actors and stakeholders involved.
14. The central challenge of contemporary architecture in the historic urban landscapeis to respond to development dynamics in order to facilitate socio-economicchanges and growth on the one hand, while simultaneously respecting theinherited townscape and its landscape setting on the other. Living historic cities,
especially World Heritage cities, require a policy of city planning andmanagement that takes conservation as one key point for conservation. In thisprocess, the historic city’s authenticity and integrity, which are determined byvarious factors, must not be compromised.
15. The future of our historic urban landscape calls for mutual understanding between
policy makers, urban planners, city developers, architects, conservationists,property owners, investors and concerned citizens, working together to preserve
the urban heritage while considering the modernization and development ofsociety in a culturally and historic sensitive manner, strengthening identity andsocial cohesion.
16. Taking into account the emotional connection between human beings and theirenvironment, their sense of place, it is fundamental to guarantee an urban
environmental quality of living to contribute to the economic success of a city andto its social and cultural vitality.
17. A central concern of physical and functional interventions is to enhance quality oflife and production efficiency by improving living, working and recreational

conditions and adapting uses without compromising existing values derived fromthe character and significance of the historic urban fabric and form. This means
not only improving technical standards, but also a rehabilitation and contemporary
development of the historic environment based upon a proper inventory andassessment of its values, as well as adding high-quality cultural expressions.

D.

GUIDELINES for CONSERVATION MANAGEMENT
18. Decision-making for interventions and contemporary architecture in a historicurban landscape demand careful consideration, a culturally and historic sensitive
approach, stakeholder consultations and expert know-how. Such a process allows
for adequate and proper action for individual cases, examining the spatial context
between old and new, while respecting the authenticity and integrity of historicfabric and building stock.
19. A deep understanding of the history, culture and architecture of place, as opposed
to object buildings only, is crucial to the development of a conservation
framework and single architectural commissions should be informed by urbanism
and its tools for analyses of typologies and morphologies.
20. An essential factor in the planning process is a timely recognition and formulationof opportunities and risks, in order to guarantee a well-balanced development anddesign process. The basis for all structural interventions is a comprehensive
survey and analysis of the historic urban landscape as a way of expressing values
and significance. Investigating the long-term effects and sustainability of theplanned interventions is an integral part of the planning process and aims at
protecting the historic fabric, building stock and context.
21. Taking into account the basic definition (according to Article 7 of thisMemorandum), urban planning, contemporary architecture and preservation of thehistoric urban landscape should avoid all forms of pseudo-historical design, as
they constitute a denial of both the historical and the contemporary alike. One
historical view should not supplant others, as history must remain readable, while
continuity of culture through quality interventions is the ultimate goal.

E.

GUIDELINES FOR URBAN DEVELOPMENT
22. Ethic standards and a demand for high-quality design and execution, sensitive tothe cultural-historic context, are prerequisites for the planning process.
Architecture of quality in historic areas should give proper consideration to thegiven scales, particularly with reference to building volumes and heights. It is
important for new development to minimize direct impacts on important historicelements, such as significant structures or archaeological deposits.

Vienna Memorandum and Decision 29 COM 5D

WHC-05/15.GA/INF.7, p. 4

23. Spatial structures in and around historic cities are to be enhanced through urban
design and art as they are key elements of the renaissance of historic cities: urban
design and art express their specific historical, social and economic components
and transmit them to forthcoming generations.
24. Preservation of World Heritage sites also involves the design of public space:particular attention is to be paid to functionality, scale, materials, lighting, street
furniture, advertising, and vegetation, to name a few. Urban planninginfrastructure in heritage zones must include all measures to respect the historicfabric, building stock and context, and to mitigate the negative effects of traffic
circulation and parking.
25. Townscapes, roofscapes, main visual axes, building plots and types are integral
parts of the identity of the historic urban landscape. With regard to renewal, thehistoric roofscape and the original building plots serve as the basis for planningand design.
26. As a general principle, proportion and design must fit into the particular type ofhistoric pattern and architecture, while removing the core of building stock
worthy of protection (“façadism”) does not constitute an appropriate mean ofstructural intervention. Special care should be taken to ensure that thedevelopment of contemporary architecture in World Heritage cities iscomplementary to values of the historic urban landscape and remains within limits
in order not to compromise the historic nature of the city.

F.

WAYS AND MEANS
27. Management of the dynamic changes and developments in World Heritage
historic urban landscapes encompasses precise knowledge of the territory and its
elements of heritage significance identified through scientific methods ofinventory, the relevant laws, regulations, tools and procedures, which areformalized in a Management Plan, according to the Operational Guidelines for
the Implementation of the World Heritage Convention.
28. The development and implementation of a Management Plan for historic urban
landscapes requires the participation of an interdisciplinary team of experts andprofessionals, as well as timely initiation of comprehensive public consultation.
29. Quality management of the historic urban landscape aims at permanent
preservation and improvement of spatial, functional and design-related values. In
this respect, special emphasis is to be placed on the contextualization ofcontemporary architecture in the historic urban landscape and Cultural or Visual
Impact Assessment studies should accompany proposals for contemporaryinterventions.

30. Economic aspects of urban development should be bound to the goals of longterm heritage preservation.
31. Historic buildings, open spaces and contemporary architecture contributesignificantly to the value of the city by branding the city’s character.
Contemporary architecture can be a strong competitive tool for cities as it attracts
residents, tourists, and capital. Historic and contemporary architecture constitutean asset to local communities, which should serve educational purposes, leisure,tourism, and secure market value of properties.

G.

RECOMMENDATIONS
32. The following considerations are directed to the World Heritage Committee andUNESCO:a) With regard to historic urban areas already inscribed on the World Heritage
List, the concept of the historic urban landscape and the recommendations
expressed in this Memorandum need to be taken into account when reviewing
any potential or ascertained impact on the integrity of a World Heritage
property. These principles should be enhanced by plans which delineate thespecific measures to be taken for the protection of the historic urban
landscape.
b) When considering the inscription of new properties and sites of historic urban
areas on the World Heritage List, it is recommended that the concept of thehistoric urban landscape be included in the nomination and evaluation process.
c)

UNESCO is invited to study the possibility for formulating a newrecommendation to complement and update the existing ones on the subject ofhistoric urban landscapes, with special reference to the contextualization ofcontemporary architecture which should be submitted, at a future date, to theGeneral Conference of UNESCO.
