The aqueduct near Vila do Abraão is an invitation to understand how water has 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 complex of the Lazareto, testaments that the municipal portal includes among the marks of the island's past. Instead of seeing the structure only as a backdrop for photos, try to recognize the elevated path and its function of conveying 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 use; a visit to the surroundings helps one realize that these activities required infrastructure. Tour suggestion: organize the walk from Abraão according to the signage 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 woods. 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 review: 09/30/2026.
