The Marmaray Tunnel is a symbol of Istanbul’s seamless blend of modern engineering and ancient history.

Stretching approximately 13.5 kilometers underwater, it holds the distinction of being the world’s deepest immersed tube railway tunnel (Marmaray Tunnel in Istanbul: History, Visiting Information, and Travel Tips).

Beyond its function as a transit solution, the Marmaray Tunnel is a window into Istanbul’s past. Its construction led to remarkable archaeological discoveries—Neolithic settlements, Byzantine harbors, churches, and Ottoman-era structures—illuminating 8,500 years of uninterrupted human habitation (Exploring Istanbul’s Marmaray Tunnel Archaeological Discoveries). For travelers, the Marmaray offers more than efficient mobility: it provides direct access to the Fatih district’s world-renowned landmarks, including the Sultanahmet Mosque, Hagia Sophia, Topkapı Palace, and museums that showcase the artifacts unearthed during the tunnel’s construction (Marmaray Tunnel Visiting Hours, Tickets, and Travel Guide for Istanbul Historical Sites).

Archaeological Discoveries at the Marmaray Tunnel

Neolithic and Prehistoric Findings

Excavations at the Yenikapı site, part of the Marmaray project, revealed Istanbul’s earliest inhabitants. Archaeologists unearthed 8,500-year-old skeletons, footprints, and tools, offering evidence of sophisticated Neolithic societies. These artifacts are displayed at the Istanbul Archaeological Museum, providing visitors with a rare glimpse into prehistoric Istanbul (Fatih Municipality).

Ancient Harbors and Maritime Heritage

Harbor of Eleutherios (Theodosius)

One of the landmark discoveries is the Harbor of Eleutherios, Constantinople’s main port from the 4th to the 11th centuries CE. The excavation exposed 25 piers and the world’s largest collection of medieval shipwrecks (Daily Sabah).

Prosphorion Harbor and Sirkeci Finds

In Sirkeci, remains of the ancient Prosphorion Harbor, dating back to the 7th century BCE, were uncovered. These sites highlight Istanbul’s long-standing maritime tradition, with layers of artifacts from different eras on display.

Byzantine and Ottoman Period Discoveries

Marmaray tunnel works revealed foundations of Byzantine churches, cemeteries, and urban infrastructure from the 12th and 13th centuries CE. Near Mihrimah Sultan Mosque, visitors can observe the remains of an apsidal church and related burial sites. Ottoman-era finds include cisterns, wells, and residential buildings, tracing the evolution of urban life after the conquest (Fatih Municipality).
