The Sultanate's Last Secret — Decode the Shirazi Cipher

🎭Your Mission

You are a French colonial archivist, dispatched in 1880 by Louis Brunet to Mamoudzou, Mayotte, tasked with unearthing a vital document that will seal

Delve into the intrigues of the Mayotte sultanate and decode the last Shirazi secret slumbering in the heart of Mamoudzou, the island's vibrant capital.

The story that haunts this land

Your quest for the Shirazi Cipher begins in Place de la République, the main public square of Mamoudzou, the administrative and commercial center of Mayotte's prefecture. Located by the sea, it is the convergence point for main streets like Rue du Commerce. The central market regularly takes place here on Wednesdays and Fridays, attracting over 10,000 weekly visitors. You can feel the echo of merchants and diplomats who, from the 19th century, made Mamoudzou a crucial crossroads between the Comoros islands and the French colonial power. Your first enigma awaits you here, hidden in the bustling alleys.

A short walk away, Mamoudzou's Covered Market, built in 1995, stands as a key location in your investigation. With its 2,500 m² housing 300 stalls, it is open Monday to Saturday and remains the primary place for selling local products such as ylang-ylang, vanilla, and spices. This symbol of the local economy connects Swahili traditions with Comorian influences. It is located just 200 m from Place de la République, accessible in less than 3 minutes on foot. In this labyrinth of flavors and colors, clues from the past intertwine with today's scents, guiding you to the next stage of your Mamoudzou journey.

Your itinerary then leads you to the Préfecture de Mayotte, a main administrative building inaugurated in 2011 after Mayotte's departmentalization (law of March 31, 2011). Occupying 8,000 m², this site is the seat of the prefect representing the French State since 1843, the year of the protectorate. Its modern facade, with elements inspired by traditional Mahoran Islamic architecture, reflects the island's cultural duality. Located 300 m from Place de la République via Rue du Commerce, the Préfecture embodies the French presence and the decisions that shaped the history of Mayotte Capitale. It is here that the crucial archives for your mission might have been hidden.

The Monument aux Morts de Mamoudzou, erected in 1922 to honor Mahoran soldiers who died during World War I, offers a contemplative pause. Its 2.5 m high bronze statue of a poilu, typical of French colonial monuments, is listed as communal heritage and was restored in 2018 following cyclones. Located opposite Place de la République, it represents a tangible link with the military history of France and Mayotte. The names engraved on this monument might hold a fragment of the code you seek, a silent tribute to intertwined destinies.

Your exploration of the candidate UNESCO Lagoon concludes on the Front de Mer de Mamoudzou, a 1.2 km coastal promenade along the Bouloua lagoon. Developed in 2015 with 4 hectares of green spaces, it hosts the Petit Port de pêche with its 150 boats and preserves the remains of the colonial quay from the 1930s. This breathtaking viewpoint over Petite-Terre and neighboring islands offers a unique perspective on Mayotte's maritime history. By following this thematic circuit through Mamoudzou, you will have not only deciphered the sultanate's secret but also explored the beating heart of Mayotte, an island with a rich heritage and complex history, rooted between tradition and modernity. Each step will have brought you closer to a deep understanding of this French Department 101.

Frequently asked questions

Q01Is The Sultanate's Last Secret — Decode the Shirazi Cipher similar to a treasure hunt?

Same spirit: search, deduce, find. But here the "treasure" is a full story to piece together in eight stops. Each stop gives you a fragment of the final code. Eight fragments later, you've cracked it.

Q02How far do you walk in Mamoudzou, Mayotte?

Usually 2 to 4 km of total walking, within 1.5 km as the crow flies from the start point. The route is designed to be walkable at a relaxed pace, no public transport needed.

Q03Is The Sultanate's Last Secret — Decode the Shirazi Cipher suitable for a challenge-seeking teen?

Absolutely. The puzzles aren't obvious — a curious teen will sweat just enough to be proud of cracking them. Progressive hints prevent frustration: if stuck, unlock hint level 1, then 2, then 3.

Q04What if we get stuck on a puzzle?

Three hint levels per puzzle, with a small increasing time penalty. If truly stuck after level 3, you can skip the step (45-min penalty). The point: nobody stays blocked and goes home frustrated.
