Dzaoudzi — Enigma of the Lost Lagoon

Your investigation begins at Dzaoudzi Jetty, the main starting point for this scavenger hunt. This location was Mayotte's historic maritime gateway, a key pier for connections to Mamoudzou and neighboring islands. As you walk through Dzaoudzi's colonial district, the former capital of Mayotte until 2000, you grasp Petite-Terre's strategic importance. Your first puzzle leads you to Fort de Dzaoudzi, built in 1889 by French colonial authorities to defend the UNESCO lagoon, a marine reserve, against external incursions. This coral stone building, classified as a Historic Monument, overlooks the jetty, a key vestige of the island's military past, occupied until the mid-20th century.

Continuing your thematic tour through Dzaoudzi's history, you arrive at Place du 29 Mai, formerly known as Place du Gouvernement. The historic administrative heart of Dzaoudzi, it housed the colonial governor's residence and was named in reference to the 1976 events related to Mayotte's accession to France. Surrounded by traditional houses and administrative buildings dating from the late 19th century, this square offers a glimpse into colonial life and the political challenges of the era. It is here that Émile Dupont's archives might have been kept, possibly revealing clues about his last expedition in the Mayotte lagoon.

The path then leads you to Dzaoudzi Cemetery, a confidential 19th-century site. This eternal resting place holds the tombs of settlers, soldiers, and early naturalists who came to explore local biodiversity. The imported marble steles, remnants of the era when Dzaoudzi was the capital (1841-2000), bear historical inscriptions about the French presence. Each stone tells a story, and it is among these silent narratives that you hope to find a trace of the disappeared naturalist. This monument of Mayotte, France's 101st department, is a poignant witness to the intertwined destinies of the island and its inhabitants.

Your stroll continues towards Dzaoudzi Lighthouse, an essential maritime element to the enigma of the lost lagoon. Built around 1900 and operational, this approximately 15-meter-high lighthouse has guided countless ships into the Mayotte lagoon. Located at Pointe Mahabou, about 1 km from the jetty, it marks a high point in your exploration. From here, the panoramic view of the lagoon and the coral reef is striking, reinforcing the link with the theme of historical marine observation. The lighthouse, a symbol of direction and vigilance, seems to hold a secret about Émile Dupont's last observations before his disappearance in 1898.

The exploration concludes at Pointe Mahabou, the southern cape of Petite-Terre, offering a panoramic view of the lagoon and its coral reef. This protected natural site, the probable end of your journey ~1.8km from the jetty, was a favored marine observation area. As an archivist, you have followed in Émile Dupont's footsteps through this thematic circuit, from fortifications to monuments, unraveling the threads of Dzaoudzi's history. This GPS scavenger hunt has allowed you to discover the French colonial heritage and the history of Dzaoudzi with your family, revealing that the mysteries of the past remain alive in the Mayotte lagoon.
