Why you should experience Tünel in Istanbul, Türkiye.
Tünel is Istanbul's living time capsule, a marvel of engineering that still hums with 19th-century charm.
Tucked quietly at the southern end of İstiklal Street near Karaköy, this unassuming station is home to the world's second-oldest underground railway, a Victorian-era wonder that's been carrying Istanbulites up and down the hill since 1875. As you step inside, the polished wood, brass fittings, and vintage signs recall an age when travel itself was a form of ceremony. The funicular's gentle rumble vibrates through the tiled walls, its rhythm connecting modern commuters with generations past. In a city built on layers of history, Tünel is a rare point where the old and new touch, a living reminder that progress doesn't always erase its past. Riding it is less about speed and more about continuity: a small, beautiful journey through time.
What you didn’t know about Tünel.
The Tünel, inaugurated in January 1875, predates even the London Underground's deep-level lines, making it one of the oldest subterranean rail systems in the world.
Its creator, French engineer Eugène-Henri Gavand, designed it to solve a uniquely Istanbul problem, the steep slope connecting the port of Galata with the Pera district above. Originally powered by steam engines, the system carried horse-drawn carriages, merchants, and dockworkers who would otherwise climb the grueling incline daily. The line runs just 573 meters but ascends nearly 60 meters, a feat that impressed engineers across Europe. Electrified in 1910 and restored in the 1970s, it now carries over 15,000 passengers a day while retaining its 19th-century aesthetic. The original wooden cars, preserved in the Istanbul Railway Museum, show the craftsmanship of an era when function and beauty were inseparable. Few know that Tünel's twin stations, Karaköy below and Beyoğlu above, were designed to resemble elegant salons, complete with arched ceilings and cast-iron detail. Today, Tünel remains not just a transit route but a cultural relic, seamlessly woven into the fabric of İstiklal Street.
How to fold Tünel into your trip.
End your walk along İstiklal Street with a ride down to Karaköy aboard this historic funicular, it's the perfect finale to the avenue's sensory journey.
The entrance is easy to miss: look for the arched doorway marked Tünel at the Beyoğlu end of the street, just before the tram line ends. Step inside, buy a single ticket or use your Istanbulkart, and take a moment to absorb the atmosphere before the short descent begins. The ride lasts less than two minutes, but its slow, mechanical glide feels meditative, a rare pause amid the city's perpetual motion. When you emerge in Karaköy, linger to watch the funicular depart again; its red-and-cream cars vanishing into the tunnel like a heartbeat beneath the city. From there, stroll to the Galata Bridge or grab coffee at one of Karaköy's waterfront cafés. Tünel isn't just the end of İstiklal, it's the quiet moment where history exhales, and Istanbul reminds you that even progress can be poetic.
