The plain and bay of Palaikastro are bounded on the south by an abrupt ridge of hills, which run out seaward into a prominent cape. Landwards, this ridge is cut off from the mass which culminates in Mt. Simódhi by a northward and a southward valley, which carry an almost impassable track from the Palaikastro plain to the cove of Karoúmes. The highest peak of this ridge, which bears the name of Petsofà, stands directly south of Roussolakkos, and rises steeply above it to a height of 270 metres. Southwards beyond the summit the slope is at first more gentle, but becomes abrupt about a quarter of a mile further on, and drops rapidly to sea-level on the south side of the promontory. The actual summit is formed by a ragged crest of limestone, precipitous on the north side, and descending less rapidly southwards into the general slope already mentioned.
Some 10–15 m. down this face, however, the natural slope of the ground is interrupted by a zig-zag terrace-wall, ABCDE, which still stands some 2·5 m. high at its external angle C, and holds up an artificial platform of made-earth within it. The little enclosure which lies against its outer face between C and D is wholly modern, though built almost wholly of ancient stones from the walls above: the older workmen described it as a ‘look-out,’ but it seemed also to have served as a sheep-pen.
