Located in the Little Africa region, in the center of Rio de Janeiro, the Valongo Wharf was revealed during the Porto Maravilha works, carried out by the Rio de Janeiro City Hall in 2011, and was recognized as a World Heritage Site by UNESCO in 2017 for being the main landing wharf for enslaved Africans in all of the Americas and the only one that has been materially preserved. In the same year, negotiations began for the revitalization project of the archaeological site.

The entire revitalization work consisted of two stages: the first of which, initiated in 2019, was carried out by IDG in partnership with the United States Embassy. The work consisted of research to identify traces of archaeological importance at the site, in addition to monitoring the start of the works and the execution of conservation procedures, such as soil cleaning, erosion control, structural reinforcement of the wall, among other interventions.

The second phase was carried out in partnership with State Grid Brazil Holding, through financing from the Social Investment for Companies (ISE) line of BNDES. idg developed and implemented the installation of the guardrail to protect the archaeological site and the public, carried out the construction of a new wall, the signage, the installation of the exhibition module and the entire urban planning project for the site. The lighting project for the historical site, which was developed by idg and implemented by the City of Rio through RIOLUZ/SMARTLUZ, was designed to highlight architectural features of the archaeological site and create a visual experience, without compromising the archaeological integrity of the site. In scenic lighting, colored lights on monuments can be used on commemorative dates in support of social causes.

The signage project, which was based on technical guidelines from Iphan and UNESCO, integrates the Valongo Wharf into the African heritage circuit in the region, connecting, through visual references and signs, other points of interest such as Pedra do Sal, the Valongo Hanging Garden, and the Museum of Afro-Brazilian History and Culture - MUHCAB. Finally, with the aim of providing information to the public that frequents the site, an open-air exhibition was implemented on the current historical importance of Little Africa, its spaces, and territorial agents.

The idg also worked on the implementation of educational projects about the Valongo Wharf. It developed and implemented Valongo, Wharf of Ideas, which trained educators to value the memories and stories of the place. The (A)gents of Valongo project was aimed at the local population of the Port Zone and aimed to encourage the exchange of ideas and knowledge about the Archaeological Site and the actions of the various agents of Little Africa. Ten virtual meetings were held with 20 institutions from the region and the participation of more than 200 people who registered, whose profile was university students and tourism professionals from Rio.

All projects developed by idg were presented and debated within the scope of the Valongo Wharf Management Committee, a governance body for the World Heritage Cultural asset, reinstated by Iphan Ordinance No. 88 of March 2023. Aimed at the shared and participatory management of the site, the group was composed of 15 institutions representing civil society and 16 governmental institutions at the federal, state and municipal levels. Among the member institutions were the Ministry of Culture (Minc), the Palmares Foundation and the Brazilian Institute of Museums (Ibram). Iphan coordinates the committee's work.
