The Gateway of the castle is named by the natives as "door of the captain", that means the door of the governor (it derives from the Italian word "capitano"). The monoliths of which it consists are remarkable as well as the iron door that remains in an excellent condition.
Cave of Olympoi
Approximately 10 km From Mesta Village, the Cave of Olympoi is a phenomenal natural wonder that was discovered as recently as 1985. Guided tours began in 2002 and though the cave is relatively small, it is filled with beautyful structures formed by mineral deposits. With magnificent stalacties cascade from the ceiling- like folds of material while stalagmites emerge from the ground mimicking bubbling water frozen in mid-sprut. The tour goes to the depth of 30 m, though the cave extents to more than 50 m.
There is a small cafeand gift shop above ground, open during the high season.
