Shared Heritage Risk in the Blue Amazon. Gamboa de Baixo Project Retrofit

This article refers to the study of the Historic Centre (CHS) of Salvador da Bahia, in Brazil, recognized as a World Heritage Site (criteria IV and V) by UNESCO, with special emphasis on the unprecedented discovery of the establishment of the LPM of 1831, for the demarcation of marine land in gamboa areas and the distinction between public and private use in Brazil.In the surrounding area, there are ruins of military fortifications with exceptional universal value in historic buildings donated to the Benedictine Order by the Portuguese settler Gabriel Soares de Sousa, which have become an area of real estate speculation, violent eviction for regional development projects aimed at high-end nautical tourism and gentrification.The Camboa fishing grounds were given by sesmaria to one of the first Portuguese to settle in Bahia, Diogo lvares Correa, popularly known as Caramuru, who married the daughter of the Taparica Indian, named Catarina Paraguau, who would have been not only the first indigenous woman, but the first woman in Brazilian history to learn to read and write.This work was started when the 200th anniversary of Brazil's Independence was approaching and the importance of Gamboa de Baixo project in the CHS, which in the prism of this research was and as the theme is not exhausted in itself, it must also always be analyzed in a historical, legal and technical context, with the aim of rescuing memories, confronting studies and assumptions that influence decision-making in the safeguarding of UNESCO World Heritage.The methodology consisted of field research, bibliographical reviews (sui generis), secondary sources, legislation, magazines, topographies, state reports, manuscript referen-1.I would like to thank the two anonymous reviewers, the first for their guidance in highlighting the historical, technical and bad practice context and avoiding subjectivity in the presentation, and the second for finding a certain political and speculative character in the text, which is only natural given the topic of contested heritage now emerging in the academic sphere.The work is based on my own research and has as its guiding thread cultural heritage institutions and policies and their "Complex Pasts: Diverse Futures", which was the theme I worked on for the International Day of Monuments and Sites in 2021, now annually promoted by ICOMOS International.The text is also supported by the lessons of the UNESCO Chair in Intercultural Dialogue in Heritage of Portuguese Influence at the University of Coimbra, the Contested Heritage course in which I participate.ces, Tombo Books and more recent materials to search for historical contexts, theoretical, technical and strategic reasons, case law and sharing models.As a result, the aim is to fill in gaps and offer contributions to the scientific community by proposing a "retrofit" that transforms threats that reduce the degree of protection of what was determined in the decision with UNESCO.
