[9] Over the years, the IAHGP has contributed to Recife's public spaces through initiatives such as installing bronze plaques that highlight the significance of monuments and locations.

In 2015, the IAHGP launched a project to install informational panels in the neighborhoods of Graças, Espinheiro, Boa Vista, and Santo Antônio.

[11] The 150th anniversary of the founding of the IAHGP was marked by a Magna session at the Santa Isabel Theater, a solemn mass at the Basilica of Our Lady of Mount Carmel, and a concert by the Pernambuco Conservatory of Music Orchestra at the Madre de Deus Cathedral.

Running from March 12 until the end of the year, the exhibition was organized into five thematic sections, or “axes,” aiming to depict life in Pernambuco during 1817 and to highlight the ideas that inspired the revolution.
