Aims: Dynamic cultural World Heritage Sites, as irreplaceable resources with tangible and intangible dimensions, have been shaped by a result of the processes of sociocultural production and experiences in the temporal and spatial context and are going through a series of changes over time. The main purpose of this research is assessing the state of conservation of dynamic cultural World Heritage Sites, which is one of the most fundamental issues in the World Heritage monitoring process.
Instrument & Methods: This study elaborates on applied-developed research methods, using an analytical descriptive method in two sections. The theoretical section is based on the logical reasoning method and technique of content analysis and logical inference; and the practical section is based on the survey method and analytic hierarchy process technique.
Findings: Achieving the effective assessment for the state of conservation of dynamic cultural World Heritage Site is based on two substantial criteria: 1) “securing and conveying cultural significance of the heritage site” with the sub-criteria of “integrity” and “authenticity”; 2) “heritage site experience” with the sub-criteria of “perception of cultural significance” and “experience of authenticity”.
Conclusion: The results show that the “sense of place attachment” indicator is the most important factor in assessing the state of conservation. And periodic use of this proposed model in the monitoring process provides a coherent platform for measuring the efficiency of the study heritage site management system. The developed framework might be used by Tehran Beautification Organization and Tehran Municipality in culturally-rich sites of Tehran.

Aims: In the protection of places with cultural significance, the identification and assessment procedure is the basic phase and generally the first step. Considering the specific characteristics of Modern and contemporary heritage, a framework for this procedure is necessary. The purpose of this research is to propose a framework based on the activities, documents and research done in this field in the global context.

Methods: This research is based on the descriptive-analytical method with library-study and logical reasoning in the three areas of registration, identification and assessment of modern works.

Findings: In this study, while reviewing the activities and researches, the criteria of the world heritage guidelines effective on the registration of modern heritage, the historical thematic identification frameworks of this heritage and a method for assessment the buildings of the era have been introduced. At the end, based on these cases, a model and framework of the assessment process of modern architectural heritage is proposed. Also, it’s usage has been investigated in a domain of Iranian heritage works.

Conclusion: A framework for the assessment process of the modern architectural heritage provides the possibility of clarifying and facilitating the registration, identification and assessment of these works. Such a framework, taking into account the nature of Modern and contemporary heritage and its commonalities in the global context, has the possibility of being formulated as a general framework. To use in a national or regional context, it is necessary to adapt it considering the historical, cultural and social characteristics of the context.

Man's past condition is related to his present life and history means surveying the quality of the past activities whose traces remain in the present time. The main field of historical research is man's past life, the stages which have been put behind in the process of evolution and changes as well as progresses made in these stages. History is a means to provide human beings with a complete insight into the events under study. Also another subject matter of history is discovering the common relations between the events, but the reconstruction of common relations is an essential part of this subject. History revives the forgotten events and by studying the cultural legacies we come to know about human past. History cannot properly play its cultural role in the form of event recording and mentioning wars and successes and only through philosophical perspective and understanding of causal relations it is possible to achieve historical goals. History is a science that studies human in the course of its evolution. And with developing connection and understanding of the causal relations of events it works with whys and states of events and by reconstructing the past cultural legacy, shows what had gone upon past inhabitants. Culture and civilization and its course in the human history is the best presentation of human development and progress and is the truest part of human history in whose course of development all members of the society take part. In the light of the above, the present article is an attempt to cast a quick look at the contribution of history to the understanding of cultures and civilizations.

 Given the importance of the historical context in the Iranian city of Mashhad and acts of sabotage, identifying, preserving, recording, and maintaining its historic facades is important. This study aims to investigate the ornamentations of Paein Khiaban’s historic facades of the Qajar period (1304-1174) (which have been inscribed as Iran’s cultural heritage). The methodology of this study is based on descriptive-analytical, exploratory, library studies, and field research. The results show that all buildings are two-story and ornamentations often seen on the upper part of the facade. In terms of ornamentation, in most of the façades, the moarragh mosaic tile or combination of tiles and bricks were used. Furthermore, some opening inscriptions are decorated with moarragh mosaic tile, too. All of these facades are made of brick and the dominant colours of the facade’ ornamentations are brown, yellow, Ultramarine and turquoise blue, lateritious and sometimes pink and white.
