Poros
Poros and the author
In order to check if it's possible to see the waypoints from any point on the mountain, I clambered up to Poros.
Cape Lougi is to the far left.
High upon the mountain, Poros is perfectly hidden for ships passing and entering any of the bays, it would've been a safe spot to live in those days. I believe Ithaca-city is hidden in much the same way.
Directly behind the village, 250 meters steep down, lies Rouda Bay.
