Gelibolu — Piri Reis Maps Enigma

Your journey begins at Gelibolu Kalesi, the Gelibolu Castle. This 14th-century Byzantine fortification, covering 2 hectares, was reinforced by Mehmed I in 1417, then rebuilt by Mehmed II after the Ottoman conquest of 1453. It is here, on these ramparts that housed Ottoman defensive cannons during the Battle of Gallipoli in 1915, that Piri Reis's first enigmas await you. The walls of Gelibolu whisper past strategies, from Byzantine emperors to Ottoman sultans, marking the starting point of your exploration of Gelibolu's heritage.

Continue to Gelibolu İskelesi, the historic port of Gelibolu, active since the Hellenistic antiquity (4th century BC). Developed in 1421 by Mehmed I for his imperial fleet, this 300-meter quay was the main Ottoman landing point in the 16th century. From here, naval expeditions departed, including those of Piri Reis in the Mediterranean. As a cartographer, Gelibolu's port activity is essential to you: observe virtual ships appearing on the water, and the trade routes of the Dardanelles Strait taking shape, helping you decipher clues related to the maritime routes of Marmara.

Your investigation then leads you to Hamza Bey Camii, erected in 1433 by Vizier Hamza Bey under the reign of Murad II. This place of prayer, in early Ottoman style, with its 12-meter diameter dome, was a spiritual anchor for Ottoman sailors, including those of the fleet where Piri Reis was active around 1513. Restored in 1912 after seismic damage and endowed with a 20-meter minaret in the 19th century, the Gelibolu mosque is an architectural testimony where your clues might be engraved, revealing information about the admiral's travels and discoveries.

The itinerary continues to Gelibolu Feneri, the Gelibolu Lighthouse, built in 1828-1829 under Mahmud II. With its height of 19 meters and its range of 18 nautical miles, this Ottoman lighthouse was vital for navigation in the Dardanelles Strait, an area meticulously mapped by Piri Reis in 1513. Electrified in 1927 and restored in 2002 by the Turkish Directorate of Lighthouses, it symbolizes the continuity of maritime surveillance. Here, the lighthouse's lights illuminate fragments of ancient maps, guiding you to the next stage of your mission in Gelibolu.

Finally, your quest leads you to Gelibolu Tarihi Yarımada Milli Parkı, the Gallipoli Peninsula Historical National Park. Declared a national park in 1973 and listed on the Turkish National Heritage List in 1990, this 33,000-hectare site covers the peninsula. It houses Byzantine and Ottoman remains from the 14th-15th centuries, as well as memorials for the 250,000 soldiers of the 1915 battles. It is in this historical setting that you will assemble the last pieces of the puzzle, understanding the strategic importance of Gelibolu and the legacy of Piri Reis, a true keystone of Marmara's heritage.
