The aqueduct near Vila do Abraão is an invitation to understand how water played a role in the history of Ilha Grande. Its arches and structural remains can be observed in dialogue with the vegetation and the historical Lazareto complex, testimonies that the municipal portal includes among the marks of the island's past. Rather than seeing the structure just as a backdrop for photos, try to recognize the elevated path and its function of carrying water: a reading that brings together engineering, environment, and daily life. The history of the Lazareto, studied in research published in 'História, Ciências, Saúde – Manguinhos', involves quarantine, sanitary control, and prison uses; a visit to the surrounding area helps to realize that these activities required infrastructure. Tour suggestion: organize the walk starting from Abraão according to the signs and current conditions, setting aside time to observe the remains without rushing. Do not walk on the arches, do not remove materials, and do not create shortcuts in the forest. After rain, roots and stones can be slippery. Confirm open trails and consider local guidance; do not assume lighting or safe access at night. Sources: Visite Angra and research on the Lazareto. Editorial revision: 09/30/2026.
