Visualização do projeto de restauro, Victor Hugo Mori/IPHAN The latest restoration project developed for the Santo Amaro da Barra Grande Fortress was proposed and carried out by Lúcio Costa at the end of the 20th century (covering from 1994 to 2000). The restoration consisted of a delicate modern metallic structure that only supported the extremities of the ruins of the central pavilion, spanning a 40 meter open area. Architect Victor Hugo Mori, of IPHAN, Instituto do Patrimônio Histórico e Artístico Nacional (the National Institute of Artistic and Historic Legacy), describes it as: "A Spanish design made of CAC steel that obeys the requirements of the Venice Charter (1964), which establishes: "any complementary work recognized as indispensable due to technical or aesthetical reasons must stand out from the architectonic structure and should display the mark of our era."
