When heritage policies and benefits have gradually enabled the process of renovation of the most attractive historical centres, the densest and poorest of them, not being able to count on the rescue provided by tourism, are doomed to suffer from their loss of ‘utilitas’. The double historic centre of the Sicilian city of Ragusa could be a perfect case offering an opportunity to experiment with the innovative potential of this condition. Ragusa is currently a city with the highest ratio of the real estate surface per capita in Italy. If today Ragusa Ibla regained its vitality as a tourist and nightlife destination, Ragusa Superiore needs a new and extensive regeneration process to be launched, which requires comprehensive planning strategies to be adopted and strong economic subsidies to be secured – as the first step, by organising an architectural and urban planning workshop devoted entirely to the historic centre of Ragusa Superiore, a part of a cycle of International Designing Workshops "Territories in Evolution” and drew on its years of experience. In any case and in each and every urban centre, basing on a general, common programme drawn up in advance, the objective of any designing workshop is to concentrate proactive skills of an international working group ‘in situ’. The Re-use Ragusa workshop very quickly unleashed a number of ideas, the effects of which can be considered specific and realistic methods of reviving the historic Ragusa. Thanks to the work during the workshop “Re-use Ragusa: Sustainable Strategies to Revive the City Centre”, the students and lectures who were lucky enough to experience the town on a daily basis: live and work here, recollecting their experience of only two weeks in the historic centre of Ragusa Superiore, demonstrated to themselves and to the town residents that positive thinking about an urban and architectural design may offer new perspectives which can creatively benefit from and enhance the already existing resources. The effects of this workshop are the fruit of successful, if unusual, cooperation between municipal authorities and administrators on the one hand and the university on the other, organising this wider highly professional international support.

The Sicily island is rich in high quality rock raw materials and has a long historical culture in natural stone production. The resources of limestone, marble, sandstone and basalt in Sicily are huge and exploited for many centuries. Its biggest city centers and historical monuments are adorned with locally quarried marble, limestone and lava stone from the Etna volcano. Exploring the raw materials potential was closely related to the development of first Sicily inhabitants who initially used available natural stones adapting them for their basic needs. The art of using stones - in the field of building structure improvement, and the use of impressive rock varieties in sculpture and art decoration were developed by ancient Greeks, Romans, and later Arabs and Normans who invaded this island. In many Sicilian cities it is possible to trace new objects growing on the older buildings, which are characterized by the invader cultures or new trends in construction. Material culture of stone applied in Sicilian construction and architecture was developed with the emerging styles. For the construction of these historical buildings, a local stone on the island has been used.

Neptunian sills at Rocca Busambra, a fragment of the Trapanese/Saccense Domain in western Sicily, host the most abundant ammonite and gastropod fauna which has ever been recorded from the Jurassic of the western Tethys. The fauna is dominated by parautochthonous organisms which were swept into the sills by gentle transport. Ammonites are characterized by perfect preservation and small size, a feature which is due to the predominance of microconchs but also of stunting. The most complete sill is 0.7 m thick and could be separated into 17 levels which range in age from the early Toarcian into the late Kimmeridgian, thus representing the most extreme case of palaeontologically and depositionally documented stratigraphic condensation in Earth history. The unique feature of the Rocca Busambra sills is due to the interaction of three processes: extreme stratigraphic condensation on the sea floor, weak tectonic fracturing of the host rock and repeated reopening on top of already existing sills. Contrasting percentages of gastropods in individual levels reflect sea-level oscillations which correspond to long known low- and highstands during the Jurassic of the western Tethys. Comparisons with other ammonite-bearing sill faunas reveal several similarities, but represent only short-timed phases of tectonic pulses and deposition.

The current knowledge of freshwater entomostracans from Sicily and some neighbouring central-Mediterranean countries is briefly reviewed. Data concerning different countries and different taxonomical groups are markedly inhomogeneous and often far from being representative of the real biota of the corresponding countries. This gap prevents a sound, biogeographical analysis of the freshwater microcrustacean fauna of the area. The major gaps that have to be filled are highlighted and the need for more surveys and monitoring is emphasised.
