Battlements of the fortification wall - Crustation Cl - anions reach maximum concentrations at the position 5 (next to the sea) and the positions of the moat (12 and 17b) oriented such that north-west winds hit the highest levels of the masonries SO 4 2- anions reach their maximum concentration at the same positions due to the heavy car traffic at these areas. In particular, the sea-facing sides are impacted by the air pollution of the nearby port and its related traffic. Positions 12 and 17b are heavily effected by the pollutants carried from the centre of the city by the northwest winds Prof. Antonia Moropoulou – Topic 6 .4 : Innovative concepts & technologies Moropoulou, A., Theoulakis, P., Chrysophakis, T., “Correlation between stone weathering and environmental factors in marine atmosphere”, Atmospheric Environment, 29, No 8 (1995) pp. 895-903 5 17 12

Educational Linkage Approach In Cultural Heritage Application of non-destructive techniques for decay mapping Digital Image Processing provides with the characteristic distribution of the decay types , based on the microstructural properties of the decayed stone (porosity, pore size distribution, texture) that aid in the understanding of the assigned pseudocolors Fibre Optics Microscopy provides information for the texture of the materials’ surface and is supplamental to the digital image processing technique, allowing the differentiation of decay types such as alveolation and hard carbonate crust Ultrasonics provide information on the depth of the decay and the decay type Infrared Thermography provides information on the distribution of humidity on the stone masonry surface The correlation of information obtained by non-destructive techniques allows for an integrated decay mapping Prof. Antonia Moropoulou – Topic 6 .4 : Innovative concepts & technologies

  • 26. Educational Linkage Approach In Cultural Heritage Venetian Fortification of Heraklion – Strategic planning of conservation interventions In order to restore integrity, durability and the mechanical properties of the historic building materials , the following interventions are required:
    • Consolidation interventions using materials compatible with the physicomechanical properties and the microstructural characteristics of the stones, to address the alveolar decay
    • Application of new restoration mortars compatible with the historic building materials of the masonry
    • Cleaning interventions based on selection criteria for the cleaning methods and materials to remove the encrustations
    Prof. Antonia Moropoulou – Topic 6 .4 : Innovative concepts & technologies
  • 27. Educational Linkage Approach In Cultural Heritage Venetian Fortification of Heraklion – Urban & Environmental Management for Cultural Heritage preservation
    • Data for the analysis of the current city plan
    • Natural relief : The morphology of the ground, the vicinity to the sea, shaping and alterations (e.g. backfilling and slope removal for the construction of the peripheral highway) in combination with the underground synthesis are factors that affect the structures in terms of foundation and the original construction materials.
    • Land Use : The incompatible use of land in the vicinity of the monument (e.g. commercial port, bus stations) has a significant impact on pollution. Their planning in new locations is urgent. Use of the land for recreation and tourism should be encouraged instead.
    • Ownership status : It is necessary to clarify the ownership status of building inside the historic city.
    • Green areas : Important biological factor, which can increase humidity levels and enhance the development of biological crusts. Mapping of vegetation is needed as part of public space planning.
    • Traffic : Increased traffic is related to pollutants emitted by cars. Any intervention on the monument should take into account traffic rearrangement, new areas for parking, pedestrianization etc.
    • Infrastructure networks: Complete mapping and documentation of historic and modern infrastructure networks are required in order to comply with modern requirements and needs
    • Population composition : A socio-economic study should describe the current status and the prevailing trends, since any interventions of the city matrix can induce significant impact on the composition of the population
    Prof. Antonia Moropoulou – Topic 6 .4 : Innovative concepts & technologies
  • 28. Educational Linkage Approach In Cultural Heritage Venetian Fortification of Heraklion – Proposal
    • Proposed interventions relate to:
    • Improvement and redistribution of traffic

    • Creation of a network of pedestrian roads
    • Restoration of the buildings facades
    • Integrated and unified approach regarding:

Educational Linkage Approach In Cultural Heritage 6.3 Strategic planning for the preservation of Cultural Heritage Conclusions The strategic planning methodology for the assessment and decision-making regarding the preservation and management of the historic cities and/or historic centers, according to their needs & future perspectives, can be accomplished by:
    • Strategic planning of the conservation interventions on historic buildings, using data management in integrated information systems for their rehabilitation and protection
      • The historic physiognomy of the historic centre is revealed and people's accessibility to cultural heritage is promoted (Athens historic centre paradigm, on the threshold of the Olympic Games 2004)
    • Strategic planning of integrated environmental management , as a tool for the sustainable development of historic cities using GIS for assessing their decay state and plan of interventions as part of the urban and land use planning of the city
      • The paradigms of medieval city of Rhodes –World Cultural Heritage Monument- and historic centre of Heraklion within the Venetian Fortifications
