📱 1 to 10 phones · 1 team per phone · Independent codes
In 1458, Prince Henry the Navigator gazed from the windswept cliffs of Sagres Promontory, the cradle of Portugal's Age of Discoveries
You are Gomes Eanes de Zurara, official chronicler of Henry the Navigator's court, tasked in 15th-century Sagres with deciphering the maritime secrets of the Sagres
Explore Sagres, a Portuguese town where the legend of the Discoveries blends with the remains of medieval fortresses and centennial lighthouses watching over the Atlantic.
Your journey begins at Ponta da Atalaia, a strategic observation point from where you can embrace the immensity of the ocean. It is here, facing the waves of the Algarve, that the Fortaleza de Sagres stands, built in the 15th century under the order of Henry the Navigator. Designed to protect the western coast against pirate attacks, this fortress, restored in 1960 after damage from the 1755 Lisbon earthquake, covers 40,000 m² with walls 2 to 3 meters thick, forming a defensive triangle. Your GPS treasure hunt invites you to explore its nooks and crannies, searching for the first clues of the prophecy.
Inside the Fortaleza de Sagres, your investigation leads you to the chapel of Nossa Senhora da Graça, dating from the 17th century, where frescoes and an azulejo altar tell centuries of devotion. It was also on this site that the ancient navigation school founded by Henry the Navigator around 1418 was located, a key place on the Portuguese Route of Discoveries. You decode symbols hidden in the azulejos, revealing information about the navigation techniques of the time, essential for progressing in your mission in Sagres.
The route then takes you to Cabo de São Vicente, the southwesternmost point of continental Europe, located 6 km from the center of Sagres. The lighthouse, built in 1846 and 30 meters high, casts its light 48 km, guiding sailors. This cape was named after Saint Vincent of Saragossa, whose relics are said to have washed ashore here in 1173. The remains of a 16th-century fortress, with its visible walls, bear witness to numerous historical shipwrecks, including that of HMS Victory in 1797. Your interactive visit to Sagres allows you to visualize lost ships in augmented reality.
Continuing your exploration of Algarve's heritage, you arrive at the Farol do Cabo de São Vicente. This lighthouse, erected in 1846 by order of Maria II of Portugal, is a cylindrical granite tower 30 m high with 69 internal steps. Initially lit by an oil lamp until 1897, it was later electrified and equipped with automatic rotation. During World War II, it was used for secret naval communications. Its visible range of 30 nautical miles in clear weather makes it an iconic monument of the region. Your outdoor escape game in Sagres invites you to use it to decipher encrypted messages.
Finally, your thematic circuit in Algarve brings you to the Fortaleza do Beliche, a small 17th-century fort (around 1630) located above Praia do Beliche. Built to defend against Barbary corsairs after the raids of 1618, it features a square shape with bastions and an internal cistern of 200 m³. Restored in 2001, it now houses a maritime interpretation center. It is from this fort that you access Praia do Beliche, a small 200 m beach with clear waters, popular for snorkeling and protected by 50 m cliffs, where archaeological excavations have revealed Roman ceramics from the 1st century. This site, accessible on foot from the São Vicente parking lot in 15 minutes, concludes your journey and offers you the key to the promontory's prophecy.
