Nowadays, virtual reality technologies and immersive virtual reality (VR) apps allow people to view, explore, engage with and learn about historic monuments and buildings, historic sites, and even historic scenes. To preserve our cultural heritage for future generations. it is essential that damaged and dilapidated historic artefacts are accurately documented, and that steps are taken to improve user experiences in the areas of virtual visits, science and education. This paper describes an approach to reconstruct and restore historic buildings and mural paintings. The work process uses digital models that are then inserted into an interactive and immersive VR environment. Windows-Mixed Reality is used to visualize the said VR environment. The work method was applied at a United Nations Educational, Scientific and Cultural Organisation (UNESCO) World Heritage Site in Tenerife (Canary Islands, Spain), thereby creating a virtual three dimensional (3D) rendering of the architectural structures of the St Augustine Church in La Laguna and its murals. A combination of topography and terrestrial photogrammetry was used to reconstruct its architectural features, and the digital imaging tool DStretch^® to recover its murals. The resulting 3D model was then inserted into an immersive and interactive VR environment created using the cross-platform game engine Unity. One of the greatest challenges of this project revolved around recovering the dilapidated and virtually nonexistent mural paintings using DStretch^®. However, the final result is an immersive and interactive VR environment containing architectural and artistic information created within the video game engine Unity, which thereby allows the user to explore, observe and interact with a cultural heritage site in real time.

This paper offers a broad vision of the potential benefits which virtual worlds may provide for improving learning, collaboration, motivation and therefore, the improvement in academic performance of students. The paper underlines how virtual worlds may offer new experimental platforms through new interactions perceiving the changeable nature of technology. The article is based on the results of the experience developed in the mainframe of the educational innovation project performed at La Laguna University during the 2012-2013 academic courses. The technological infrastructure has been created already and the 3D graphic modelling was designed using open source software aiming for creation of the ‘La Laguna Virtual University’ virtual world. Teachers have given ubiquitous classes in this virtual environment interacting with students. All feedback from teachers and students has already been gathered in this experience
