Abstract:

Introduction:
Among the challenges faced at the university, during the lockdown from mid-March 2020, is the need to give continuity to the learning of subjects that involve a direct approach to cultural property. In "Architectural History, Theory and Composition 3 - Rehabilitation", undergraduated students of the Degree studies of Fundamentals in Architecture and teachers have practiced new ways of distance learning.
Traditionally, reading and consulting materials are provided in digital formats (catalogues and urban plans, publications on buildings, urban history, cartography) and a visit of immersion in the heritage reality. Buildings, spaces and urban perceptions are identified, so that students develop ways of seeing and recognize their complexity. The social, cultural, artistic, archaeological, landscape dimension prepares preservation or rehabilitation practices. This includes a visit to a qualified sector of the historic centre of Seville.

Justification and objectives:
The experiences of urgently developing resources for teaching in the lockdown situation have generated a new scenario. Among the objectives of this paper is to explain the immediate response and the search for alternatives to the face-to-face visit, without having the technical tools to formulate an alternative virtual visit. All this maintaining the planning of the subject and achieving the necessary learning results in three months. The objective was to motivate a social involvement of students on the problems of the heritage of Triana and to know in greater depth the field of study of their practical work.

Results:
With a simple technology, depending on the patrimonial characteristics, a virtual visit has been made, without additional economic costs, nor digitalizations with specialized equipment. Using digital elements combined, a shared four-hour online visit was made by teachers and students. Use was made of documentary and graphic resources and the work of teachers: historical cartography, with the river as the backbone, approaches to its urban spaces and associated intangible heritage (historical and recent photographs, local videos and foreign production, case of France 3, and its television program "Des racines et des ailes" dedicated to "Séville, fille du Guadalquivir"). The experience in developing teaching innovation materials with virtual and augmented reality, including monuments, vernacular architecture, spaces and urban routes, facilitated the task.
The result was an active interaction of the students during the virtual tour. The work of cataloguing singular buildings and urban spaces, with proposals for their rehabilitation and improvement of their value, including data of social association of the inhabitants of Triana (traditional crafts, customs and celebrations) and the impact of tourism was satisfactory. The experience is considered especially positive, due to the level of understanding and involvement of the proposals made, being relevant to help redefine new learning resources on urban heritage with digital technology.
