The teaching astronomical observatory of the University of Lisbon (19th century): A virtual experience

The last teaching observatory of historical interest in Portugal, from the late 19th century, is one of the most charismatic buildings of the Museums of the University of Lisbon. After 100 years of intense use, the Observatory needs structural restoration before it can be fully returned to public fruition. Recently, a group of students from this University was engaged in the construction of virtual 3D models to recreate the Observatory building and collections. This paper describes the models constructed as a tool to be used for information dissemination among broader audiences.
