Istanbul is giving new life to one of its most historic waterfront corridors through the T6 Sirkeci–Kazlıçeşme Heritage Coastal Line, a rail route that blends sustainable urban transport with centuries of cultural heritage. Running alongside the Sea of Marmara, the scenic line follows a former railway corridor that has been transformed into a pedestrian-friendly public space while maintaining rail connectivity between some of Istanbul’s most significant historical districts.

Stretching from Sirkeci Station to Kazlıçeşme, the T6 line offers visitors an alternative way to discover Istanbul beyond its busiest tourist routes. Linking landmarks such as the legendary Sirkeci Orient Express Terminal, Gülhane Park, the vibrant seafood neighbourhood of Kumkapı, and the imposing Yedikule Fortress, the railway provides a unique combination of history, architecture, coastal scenery and local culture.

As Türkiye continues investing in sustainable tourism and heritage conservation, the T6 corridor demonstrates how historic transport infrastructure can be reimagined to enhance visitor experiences while preserving the city’s rich past.

A Historic Railway Corridor Reimagined

The T6 Heritage Coastal Line follows one of Istanbul’s oldest railway alignments, once an important gateway connecting the city with Europe.

Instead of allowing the historic corridor to fade into history, authorities have transformed it into a modern urban transport route complemented by landscaped walking paths, cycling areas and public spaces overlooking the Sea of Marmara.

The result is an experience where visitors can combine sightseeing with leisurely walks, rail travel and waterfront relaxation in one continuous journey.

The project also reflects Istanbul’s broader commitment to integrating heritage preservation with contemporary urban mobility.

From Sirkeci to Kazlıçeşme: A Journey Through History

The T6 line begins at Sirkeci Station, one of Europe’s most iconic railway terminals.

Internationally famous as the eastern terminus of the legendary Orient Express, Sirkeci remains an important symbol of Istanbul’s historic role as the meeting point between Europe and Asia.

From there, the route continues through:

• Cankurtaran, close to many of Istanbul’s most famous monuments.
• Kumkapı, renowned for its traditional seafood restaurants and lively atmosphere.
• Yenikapı, a major transport interchange with archaeological significance.
• Yedikule, home to one of the city’s best-preserved Byzantine fortresses.
• Kazlıçeşme, where visitors can continue exploring Istanbul’s revitalised coastal parks.

Each stop introduces travellers to a different chapter of Istanbul’s long and fascinating history.

Sirkeci Opens the Door to Istanbul’s Historic Peninsula

For many visitors, Sirkeci serves as the perfect starting point.

Within walking distance are some of Türkiye’s most celebrated attractions, including Gülhane Park, a peaceful green space that once formed part of the gardens of Topkapı Palace.

Nearby streets also lead towards the Historic Peninsula, allowing visitors to explore centuries of Ottoman and Byzantine heritage before continuing along the coastal railway.

The preserved architecture surrounding Sirkeci creates an atmosphere that reflects Istanbul’s unique position between continents and civilisations.

Kumkapı Showcases Istanbul’s Culinary Heritage

One of the highlights of the journey is Kumkapı, a district famous throughout Türkiye for its seafood restaurants.

Visitors can enjoy freshly prepared fish, traditional meze dishes and lively street-side dining while overlooking the Marmara coastline.

The neighbourhood’s multicultural history, narrow streets and waterfront setting make it a favourite destination for both local residents and international travellers seeking authentic Istanbul experiences beyond the city’s major landmarks.

Yedikule Fortress Preserves Byzantine History

Further along the route lies Yedikule Fortress, often referred to as the Yedikule Dungeons.

Originally constructed as part of the Theodosian Walls, the fortress later became one of the Ottoman Empire’s most important defensive structures and state prisons.

Today, visitors can explore its towers, courtyards and historic walls while enjoying panoramic views over the Sea of Marmara.

The fortress provides valuable insight into Istanbul’s Byzantine and Ottoman past, making it one of the city’s most significant historical attractions.

Walking Along the Ancient Theodosian Walls

One of the greatest advantages of the T6 line is its easy access to the Theodosian Walls, among the world’s best-preserved ancient city fortifications.

Travellers can disembark and enjoy leisurely walks beside these monumental walls, discovering centuries of history while taking in sea breezes from nearby Kennedy Avenue.

The combination of pedestrian-friendly pathways and rail connectivity encourages slower, more immersive exploration of Istanbul’s historic waterfront.

Sustainable Tourism Along the Marmara Coast

The T6 Heritage Coastal Line supports Türkiye’s broader tourism strategy by encouraging visitors to use public transport while exploring lesser-known cultural districts.

By combining heritage conservation, green public spaces and modern mobility, the project helps distribute visitor activity beyond Istanbul’s busiest tourism hotspots.

This approach supports local businesses, promotes environmentally responsible travel and enhances the overall visitor experience through accessible, scenic and culturally rich urban journeys.
