The castle of Gresti or Pietratagliata is located near the village of Aidone. Its current condition is that of ruin even if well legible in the forms that are composed mainly of a mighty tower full and a series of rooms ingrottate. The first historical news documented dating back to the 14th century. The castle stands on a high rocky ridge of sandstone. The central part, the spur higher, has been used by man for its strategic position as a control station and defense. In fact the castle constitutes an outpost or a fortress of sighting for the control of a vast territory, connoted by important streets of communications which from the eastern coast is addentravano toward the center of Sicily dominated by settlements which Morgantina, Enna, Agira.
The structure extends over four levels: on the first level, which is also the oldest to be found in the rural houses and a large cave which opens with a loggia south and with a window and loggia and north. At the second level from which also begins the tower full and part the scale dug in the rock, there are two local: an input and a room with window delimited by benches in masonry. At the third level, the second floor where you find the environments 'noble' representation, there are four rooms dug in the rock and other in masonry. The fourth level is present an environment with entrance portal which would suggest a chapel and a cistern to collect rainwater. A mention deserves the high tower full, firmly anchored to the rock, visible at large distances. Has walls from compact surfaces, underlined by sharp built in blocks of stone perfectly squared; access to the terrace of the tower was allowed by a beautiful spiral staircase, with steps of basalt, placed in the corner of the south-east.
For the structure and for some particular aspects, the castle may not have had the function of an aristocratic residence, but was certainly a fortress of sighting within the valley of Gornalunga that, from the earliest times, has made a connection between the Ionic coast and the interior. The presence of numerous castles like (some today recognizable only by the toponymy) suggests plausible to assume that the castle had inserted inside a network of optical signals, defined anciently fani or fires, which allowed to rapidly transmit a signal even at a great distance.References:
From 1239, Raynaud, the Bishop of Quimper, decided on the building of a new chancel destined to replace that of the Romanesque era. He therefore started, in the far west, the construction of a great Gothic cathedral which would inspire cathedral reconstructions in the Ile de France and would in turn become a place of experimentation from where would later appear ideas adopted by the whole of lower Brittany. The date of 1239 marks the Bishop’s decision and does not imply an immediate start to construction. Observation of the pillar profiles, their bases, the canopies, the fitting of the ribbed vaults of the ambulatory or the alignment of the bays leads us to believe, however, that the construction was spread out over time.
The four circular pillars mark the start of the building site, but the four following adopt a lozenge-shaped layout which could indicate a change of project manager. The clumsiness of the vaulted archways of the north ambulatory, the start of the ribbed vaults at the height of the south ambulatory or the choice of the vaults descending in spoke-form from the semi-circle which allows the connection of the axis chapel to the choir – despite the manifest problems of alignment – conveys the hesitancy and diverse influences in the first phase of works which spread out until the start of the 14th century.
At the same time as this facade was built (to which were added the north and south gates) the building of the nave started in the east and would finish by 1460. The nave is made up of six bays with one at the level of the facade towers and flanked by double aisles – one wide and one narrow (split into side chapels) – in an extension of the choir arrangements.
The choir presents four right-hand bays with ambulatory and side chapels. It is extended towards the east of 3-sided chevet which opens onto a semi-circle composed of five chapels and an apsidal chapel of two bays and a flat chevet consecrated to Our Lady.
The three-level elevation with arches, triforium and galleries seems more uniform and expresses anglo-Norman influence in the thickness of the walls (Norman passageway at the gallery level) or the decorative style (heavy mouldings, decorative frieze under the triforium). This building site would have to have been overseen in one shot. Undoubtedly interrupted by the war of Succession (1341-1364) it draws to a close with the building of the lierne vaults (1410) and the fitting of stained-glass windows. Bishop Bertrand de Rosmadec and Duke Jean V, whose coat of arms would decorate these vaults, finished the chancel before starting on the building of the facade and the nave.
Isolated from its environment in the 19th century, the cathedral was – on the contrary – originally very linked to its surroundings. Its site and the orientation of the facade determined traffic flow in the town. Its positioning close to the south walls resulted in particuliarities such as the transfer of the side gates on to the north and south facades of the towers: the southern portal of Saint Catherine served the bishop’s gate and the hospital located on the left bank (the current Préfecture) and the north gate was the baptismal porch – a true parish porch with its benches and alcoves for the Apostles’ statues turned towards the town, completed by an ossuary (1514).
The west porch finds its natural place between the two towers. The entire aesthetic of these three gates springs from the Flamboyant era: trefoil, curly kale, finials, large gables which cut into the mouldings and balustrades. Pinnacles and recesses embellish the buttresses whilst an entire bestiary appears: monsters, dogs, mysterious figures, gargoyles, and with them a whole imaginary world promoting a religious and political programme. Even though most of the saints statues have disappeared an armorial survives which makes the doors of the cathedral one of the most beautiful heraldic pages imaginable: ducal ermine, the Montfort lion, Duchess Jeanne of France’s coat of arms side by side with the arms of the Cornouaille barons with their helmets and crests. One can imagine the impact of this sculpted decor with the colour and gilding which originally completed it.
At the start of the 16th century the construction of the spires was being prepared when building was interrupted, undoubtedly for financial reasons. Small conical roofs were therefore placed on top of the towers. The following centuries were essentially devoted to putting furnishings in place (funeral monuments, altars, statues, organs, pulpit). Note the fire which destroyed the spire of the transept cross in 1620 as well as the ransacking of the cathedral in 1793 when nearly all the furnishings disappeared in a « bonfire of the saints ».
The 19th century would therefore inherit an almost finished but mutilated building and would devote itself to its renovation according to the tastes and theories of the day.
