It presents little outstanding slopes, the top culminates with a small platform with both Islamic materials, dateable at the end of the 13th century, and the Bronze (Site studied in the work done by the research grant of the Juan Gil Albert Studies Institute 1989, with the title of Prehistoric Poverty of the Alto Vinalopó).

A few meters from the site of “La Fantasmeta”, a cyclopean structure, known as “La Caseta dels Corps”, it has two large slabs of limestone arranged vertically, parallel to a step of the natural rock of the hill of 1 ’10 m tall. On both of them, a slab of large dimensions is arranged as a roof.

This structure presents an open face to the N / NE, to which a block line of limestone is attached, arranged in a semicircle whose axes are born in the walls of the structure, forming a possible chamber or anteroom.

In the enclosure, located in the mount San Bartolomé, two types of construction are observed, the tapial of the linen cloth of the wall, of Muslim origin, and the basal sillarejo of the tower more typically Christian. The works carried out pursue two fundamental objectives: on the one hand the design of the spatial distribution, based on the uncovering of wall structures that would allow, together with the findings, the knowledge of the different functions of each sector and, in this way , it would help us to rebuild your plant. On the other hand, knowing the chronology of the place and its occupational evolution, this is achieved through the study of materials, especially ceramics, and the study of the strata.

The materials found show a settlement corresponding to the Bronze Age, handmade ovoid vessels, loom weights and hand mills, a settlement that is interrupted during the Iberian period and again a reoccupation showing the medieval materials. These are for the most part ceramic, although fragments of small bottles, jars and small glasses of glass, small objects of bone, and also of bronze and iron are also important. It is the common ceramics the most abundant, ataifores, phials, jars, jars, lamps, basins, lids, casseroles, stoves …

The decorations of the rest of the ceramic group correspond to incisions, laces decorated with fingerings and ungulations, painting, dry rope, printed green purple and scribed. All this material is very fragmented is under study a ceramic material of this last campaign, which could delay the end of the occupation of the castle to more modern dates. The stratigraphy shows in some places vestiges of fire, which must be paralyzed with the types of findings.

In medieval times there is the substitution of the Muslim conception of the castle as the unifier of the surrounding farmsteads, for the Christian one that used fortification to control the territory.

Hardly remains a tower of square base, disguised with a roof, to which the hermitage of San Bartolomé was added to him, in the hill of the same name. This tower dates from the 14th century, and for its construction, ashlars, basal ashlar and masonry, typically Christian materials were used. In its walls there are only two open windows and five windows blinded, four of them in the upper part, one on each side. From its interior this upper part resembles a pigeon house. The beams that support the roof are made of wood.

This stone is located between two enclaves of considerable importance in the history of the past of this area, the two hills or hillocks located on its right and left and in which physical remains of certain relevance belonging to the Bronze have been found. These engravings belong to the Bronze Age, although not the whole, some are of greater antiquity. In some of these stones is the sign of the labyrinth; This is not very common to find in many places, the place where it is most representative is Galicia.

Some of the signs within “Les Graelletes”, we could also affirm that they are, of those determined as fusiform, and there are parallelisms with other studied zones although not very close geographically.

Situations of overposition or approximation of some of the motifs, or of repetition, seem to be that they respond in almost all the petroglyphs of many places, even outside the Peninsula, to which they begin to engrave or carve primitive cultures that span very long periods in time, and each one with its peculiarities, and finding in all historical moments the deepest magical-religious feeling and in all cases something supernatural.
