Conference Excursion - Proposed

Accompanying persons

There is a minimum package for accompanying persons which includes: social dinner, welcome cocktail and excursion. There will also be the possibility to join the lunches and to make additional excursions on the days of the conference. On request it will also be possible to take advantage of a babysitting service, in spaces close to those of the conference.
For the half-conference excursion, it was decided to propose to the participants 4 different alternatives, usable in comfort even by small groups. The 4 proposals are:


45 km from Alghero there is a small village of ancient origins, one of the most picturesque in Italy. Crossed by the river Temo (the only navigable river in Sardinia) it is characterized by the typical colored houses in pastel tones, the wrought iron balconies, the narrow alleys of the historical center and it is dominated by a medieval castle.

Neptune’s grotto

The Neptune’s Grotto are among the largest marine cavities in Italy, one of the most fascinating jewels of nature in the Mediterranean. Their formation dates back to about two million years ago: inside they can be admired rooms with amazing karstic conformations, a white sandy beach and a huge underground lake. The caves have a horizontal development of about four kilometers at the same level as the surface of the sea (the tourist itinerary extends for about 1 km). Distant 24 kilometers from Alghero, they are the pride of the marine protected area of Capo Caccia-Piana island, within the Porto Conte park. It can be reached by boat, leaving from the port of Alghero, enjoying the spectacle offered by the cliffs overlooking the sea.

Porto Conte Park - Punta Giglio

A few km. from Alghero, inside the Porto Conte Park, it is possible to take an excursion along the Punta Giglio path. The light, mainly naturalistic trekking route winds along a dirt path, under the shade of the pines, where the sea appears between rocks and coves. Here the maquis and the pine forest coexist well with numerous animals that have found a home there: the white snake, the turtle, the fox, the boar and several species of birds. Before reaching the promontory of Punta Giglio, the pine leaves room for agave, Phoenician juniper, helichrysum, limonium, rosemary, dwarf palm and mastic. Hidden by vegetation is the swallow-hole of Dasterru, a vertical well where the remains of the Neolithic man were found. Arrived at the top, where the natural silence is broken by the voices of the seagulls, among clear evidence of military archeology, the cliff, overlooking the sea, appears in all its beauty.

Palmavera nuragic area

The fourth excursion proposed concerns a symbol of the ancient history of Sardinia: the nuraghi, a UNESCO World Heritage Site since 1997.
The Nuragic complex of Palmavera is located in north- west Sardinia, between the gulf of Alghero and the gulf of Porto Conte. It consists of a nuraghe, a big barbican (built of multilobed calcareous blocks) which connects four tower-huts, and a village all around. The nuraghe consists of a main tower, partially enclosed in a bastion, a courtyard, a secondary tower and a short corridor with niches. One of the tower-huts in the barbican is different from the others: it is the so- called “meeting hut”, typical of Nuragic villages. Perhaps reserved to a council of elders, it is a big round hut (8,87m diameter) with a bench along the foundation wall and a circular base in the middle in order to support a sacred sculpture. The richest families probably lived inside the barbican, while the other families outside. The village of Palmavera counts about fifty among huts (circular in plan and built of calcareous blocks) and delimited areas. The complex was built in three stages, from the 15th to the 8th century BC.
