Tomb of Kar, beginning of ancient Scironian Odos, Municipality of Megara

West of the city of Megara and next to the National Road, on a hill at the beginning of the ancient Skironian Odos, the foundations of a large circular building are preserved, which is probably related to a tower - observatory that controlled the passage of Skironidos road and ensured the safety of passers-by in times of war. This monument has also been identified as the tomb of Kar, after the legendary king of Megara, or as the tomb of the flutist Telefanes. Both of these monuments are mentioned by Pausanias as being on the ancient road that connects Megara and Corinth.
