Karfi (also Karphi, Greek: Καρφί) is an archaeological site high up in the Dikti Mountains in eastern Crete, Greece. The ancient name of the site is unknown; "Karfi" ("the nail") is a local toponym for the prominent knob of limestone that marks the peak of the site, especially when viewed from the north. Located approximately 1100 meters above sea level, and overlooking the northern entrance to the Lasithi Plateau, the dramatic situation of Karfi is somewhat akin to that of the famous Inca site of Machu Picchu in Peru. While there is some evidence that the site was used during the Middle Minoan period as a peak sanctuary, Karfi is best known as a large and extensively excavated town of the Late Minoan IIIC period (around 1200–1000 BCE) at the beginning of the Greek "Dark Ages."
The peak of Karfi was originally a peak sanctuary, occupying a typical site on a high shoulder (some 1.1 km above sea level) with a wide "viewshed" (Soetens, Driessen et al.) that connected it with sightlines to other sites, typical of the network developed in the "first Palace period" (Middle Minoan IB–II, 1900–1800 BCE) onwards, but probably abandoned, perhaps under increased religious centralization, in Middle Minoan IIIA (ca 1650 BCE) (Soetens, Driesen et al.). The rocky site is dominated by a bifurcated stone outcropping that is unmistakably like the carved and shaped crescent horn stone altars known in Crete and Cyprus.
