The ancient tunnel of Eupalinos in Samos, Greece (educational activity Ellinogermaniki Agogi)

 This scenario involves different Applied Geometry concepts (angles and orientation, congruent triangles) and Topographic Maps representations (elevation and contour lines) in order to “manipulate” the alignment of the Eupalinos Tunnel which is considered as one of the most important engineering achievements of antiquity. Eupalinos worked as a modern engineer 2500 year ago without using any digital devices, GPS etc., hence, a question arises: “Is it simple to succeed such a task with the use of modern technologies and digital tools?”
