Historic Site · Landmark
The Tunnel of Eupalinos or Eupalinian aqueduct (Greek: Ευπαλίνιον όρυγμα, romanized: Efpalinion orygma) is a tunnel of 1,036 m (3,399 ft) length running through Mount Kastro in Samos, Greece, built in the 6th century BC to serve as an aqueduct. The tunnel is the second known tunnel in history which was excavated from both ends (Ancient Greek: ἀμφίστομον, romanized: amphistomon, "having two openings"), and the first with a geometry-based approach in doing so. Today it is a popular tourist attraction.

  • You have to see and feel what it must have been like to start digging this more then 1000 meter tunnel 2500 years ago. Only by hand and with only "simple" ways to navigate through the bedrock...  more »
  • If you are even partially claustrophobic, forget about this tour. If you aren't, you are in for a treat. It is an amazing feat of skill and labor that they constructed this aqueduct over time. You cannot appreciate what it took unless you go down into it and see how they built it. Amazing!
  • Amazing place. Considering it is almost 2500 years old and built with no modern technology starting on opposite sides of the mountain, makes its existence even more incredible. Well worth a visit. Not for those with mobility problems.
