Aqueduct

Kavala's location is ideal, looking out to the island of Thassos and close to Thessaloniki, Drama and Serres. For more adventurous travelers, Istanbul is just a four-hour drive away. If you look for the city on a map, you'll see it's in the heart of northern Greece, in an ideal spot for excursions around the region.

My shoes were covered in mud. Water from the roof dripped down onto my jacket. I was walking along a 9-meter-high tunnel. My head - thankfully, I wore a helmet - bumped against the rocks several times. But I didn't mind: Visiting the Eupalinian Aqueduct is a unique experience.

The Tunnel of Eupalinos, one of the most extraordinary monuments of craftmanship and construction (1,036 metres carved inside the mountain that towers over the town of Pythagorio on Samos) will be very soon accessible.

A photograph made available on Tuesday shows the inside of the tunnel of the Eupalinian Aqueduct in Pythagorio on the island of Samos, after its restoration. The work on the 1,036-meter tunnel was completed on Monday, reopening to the public the 6th century BC monument, which is regarded as one of the most important technical works of ancient times.

The aqueducts in the ancient city of Aspendos, located in the southern province of Antalya's Serik district, have witnessed centuries of history. 

The one-kilometer-long and 15-meter-high aqueducts, which bring water to Aspendos from the mountains, reveal the talent of the engineers who built them. These rare and ancient artifacts are called the lifelines of the city. 

Clever feats of engineering that required precise calculations of slope and hill elevation, Istanbul’s aqueducts crisscrossed the city, bringing water to the imperial city Today in Istanbul we cross under the Aqueduct of Valens, but give this ruined, fourth-century structure little thought as we try to navigate traffic.

The filming of a documentary on Istanbul’s masterpiece the Mağlova aqueduct has begun.
