Tünel Funicular – Historic Underground Railway of Istanbul

The Tünel Funicular, often simply called Tünel, is one of Istanbul’s most unique historical transportation systems. Located at the end of Istiklal Street, the funicular connects the districts of Beyoğlu and Karaköy.

Despite its short distance, the Tünel is an important part of Istanbul’s transportation history and remains a beloved landmark for both locals and visitors.

History of the Tünel

Construction of the Tünel began in 1871 during the late Ottoman period and the system officially opened on January 18, 1875.

It was designed by French engineer Eugène-Henri Gavand, who proposed the underground railway to make travel easier between the busy commercial district of Galata and the residential and entertainment center of Pera (today’s Beyoğlu).

At the time of its opening, the Tünel became one of the earliest underground railways in the world, following only the London Underground.

Engineering and Operation

The Tünel is a funicular railway, meaning two cars operate on a steep incline using a cable system.

Key features include:

• length of approximately 573 meters

• two stations: Karaköy and Beyoğlu (Tünel Square)

• steep underground track connecting the lower and upper districts

Originally the system operated using steam power, but it was later converted to electric power as technology improved.

A Historic Journey Through Istanbul

Today the Tünel continues to function as part of Istanbul’s public transportation network.

The short ride provides a quick connection between the Galata Bridge area and the upper end of Istiklal Street.

For many visitors, riding the Tünel is not only practical but also an opportunity to experience one of the city’s oldest working transportation systems.
