The international architecture student project has been started in 1995 by Claude Gaillard (ENSA Clermont-Ferrand) and Rafael Baltar (Universidad da Coruña). At its third edition in 1997, Nick Dobler (OTH Regensburg) joined the team. Each year, one of the participating institutions in turn selects the topic around the preservation and evolution of the architectural patrimony, prepares the program and hosts the workshop, which is the starting point of the project in March. After one week of conferences, site visit and joint work in mixed international teams, the students return to their university in order to work on their personal design projects. In June each year, selected students meet again at the institution which in turn hosts the following session in order to meet the jury who decides about the Grand Prix Rafael Baltar for the best project of all institutions. In 2017, the NUACA Yerevan with Emma Harutyunyan joined the team. At the 24th edition of Iacobus, there are 22 French, eight Spanish, six Armenian and seven German students participating, together with their twelve teachers, a large group, who met in the main auditory of the Faculty of Architecture at the UDC on Monday, March 11, 2019 in order to start the project of converting the site of Sta.
