Historic garden management seeks to direct the evolution of complex cultural and natural heritage sites towards best meeting the needs of their owners, visitors and community. This entails balancing the conservation of these delicate socio-ecological systems with  accessibility to the many environmental, economic and socio-cultural benefits that they provide. Thus, historic garden management must be operational, continual and sustainable; it involves multiple stakeholders, and most of all, must be adaptive. That is why it is especially useful to conceive of historic garden management as a cyclical process that loops through a strategic phase, an operational phase and an assessment phase. In order to understand the many facets and challenges of historic garden management, a systematic review was carried out on international academic literature addressing this topic, with special attention regarding the social, economic and environmental aspects of sustainability. Academic studies on this subject come from many different disciplines, making it both stimulating and fragmented. This review seeks to consolidate these interdisciplinary efforts into a clear vision, including a framework of key themes and research methods. An analysis of the reviewed literature shows that research has focused on describing the gardens themselves, with few studies interested in the people sustaining them. Future research should follow recent policy documents’ lead and pay more attention to community value and involvement.

This entry concerns the challenges and perspectives of on-site non-invasive measurements applied to valuable wall mosaics. The choice of the appropriate technique or combination of different techniques depends on a variety of factors: the depth of investigation, the resolution, the possibility to have direct contact with the surfaces or, on the contrary, limited accessibility of the wall mosaics due to their location (e.g., vaults), as well as deterioration problems, (e.g., voids, detachments, or humidity effects). This entry illustrates briefly the current state of the art in the field of non-invasive diagnostic methodsavailable for the study of wall mosaics (IRT, GPR, DHSPI, DHSPI-SIRT, SLDV, HSR), considering their potentials, limitations and future development frontiers.

The Master of Lourinhã masterpieces are the best that Renaissance painting produced in Portugal during the governance of King D. Manuel I, in the Luso-Flemish period. The paintings were commissioned c. 1515 by Queen D. Maria, second wife of King D. Manuel I. Its underdrawing, the fineness of the landscapes and the transparency of chromatic material, reveal the talent of a great artist following Bruges and Antuerpian models.

       Significant architectural and historical monuments become an important point of reference for the local population, increasing their sense of security, and act as a factor shaping social identity. An effort to preserve relevant objects in a city is therefore important both for retaining its unique features and for strengthening the local community. A significant role plays here the adaptive reuse of architectural heritage, which allows for the preservation of architectural objects that are important to the local community, promoting the integrity and historical continuity of the city while restoring the objects’ functional and economic value.         The introduction of a new function in architectural heritage is not only an important impulse for the tangible regeneration of urban tissue, but can also help to reconstruct the image and identity of a city. The local cultural and architectural heritage plays a significant role in the process leading to the creation of positive references and elimination of negative connotations related to an economic or social crisis. These remain an important part of the history of a city and, at the same time, its significance may be reimagined and shown in a new context, that relates to the present day. As a result, artefacts of the past gain new meanings, which are subject to a different, contemporary interpretation through the prism of current needs and ideas. Objects or even groups of objects from the past are being consciously taken into consideration in the activities currently undertaken. The contemporary scale of the phenomenon and complexity of the issues concerning the adaptive reuse of architectural heritage are a consequence of the multi-faceted transformations that have taken place in recent decades in the social, cultural and economic spheres, and, consequently, the contemporary understanding of the role and significance of the architectural heritage.
