In the sun-baked shores of Marsa Alam, where the Red Sea meets desert sands, a sinister Ptolemaic secret slumbers
Marsa Alam — Serpent Vein Secret
You are Dr.
Anya Sharma, an intrepid archaeo-cartographer, arriving in Marsa Alam in the present day, tasked with verifying a recently unearthed fragment of an ancient Red Sea chart.
Dive into the heart of Marsa Alam, following the footsteps of an ancient secret buried beneath the Red Sea sands.
The story that haunts this land
Your adventure begins at Port Ghalib Marina, the main departure point for snorkeling boat trips to Marsa Mubarak. This complex, officially inaugurated in 2007, was developed by the Qatari group Al Ghanim Industries to accommodate yachts up to 85 meters long. As you explore its 750 berths, you discover how this location became a major tourism hub on the Red Sea from the 2000s, symbolizing Marsa Alam's modern rise. Your first riddle awaits you here, linked to the commercial secrets that shaped this coast.
Next, walk along the Port Ghalib Corniche, a paved pedestrian promenade stretching 2 km, developed since 2007. It connects the marina to the main resort and offers views of the Gulf of Suez, particularly well-lit at night. This path reveals the tourism development efforts in Marsa Alam, initiated in the early 2000s. It is here, facing the vastness of the Red Sea, that you decipher a coded message, hidden in the pavement patterns, guiding you towards the commercial heart of the city.
The Souk of Port Ghalib, a traditional covered market adjacent to the marina, welcomes you with its stalls. Built around 2007-2010 in a modern Egyptian architectural style imitating historic souks, it houses about thirty shops selling local crafts, spices, and Red Sea products. Open daily, it is a living testament to Marsa Alam's mercantile culture. Among the scents and colors, a merchant entrusts you with a crucial clue, linked to the ancient trade routes that crossed this region.
Your quest then leads you to Port Ghalib's public beach, a 1 km stretch of white sand, accessible from the marina. This area is popular for snorkeling with coral reefs 100m from the shore and has been mentioned in local excursions since 2010 as a protected area for sea turtles. It is here, with your feet in the sand, that you activate an augmented reality device to reveal an underwater map, indicating the path to the next point of your investigation, beyond the crystal-clear waters of Marsa Alam.
Finally, the Port Ghalib Mosque, built around 2010, stands with its 25-meter-high minaret. Neo-Ottoman in style with a central dome, it can accommodate 300 worshippers and serves both the local community and tourists. This monument, although modern, embodies tradition and spirituality within Marsa Alam's tourist complex. By observing its patterns, you assemble the final pieces of the puzzle, understanding the importance of places of worship in the history of this region and revealing the secret of the Serpent's Vein, a treasure not material, but made of knowledge and local legends of the Red Sea.
