In the capital Iglesias there are numerous monuments and churches to visit, such as the Cathedral of Santa Chiara, which dates back to the end of the thirteenth century and includes numerous statues and furnishings of great value such as the late Gothic cross of the sixteenth century and the eighteenth-century painting “the Virgin of the Assumption and Saints”. Carbonia, on the other hand, is an area that was once a swamp but was reclaimed during the construction of the new city in the 1930s to house coal miners. At the entrance of the city is one of the largest mining tunnels in Sardinia, now abandoned – the Great Serbariu Mine. The old mine is now the seat of the Museo del Carbone and is a living testimony of what was the Carbonia of the past. Whilst visiting the Campidano, it is possible to admire beautiful beaches, mines, boundless wild plains and the plateaus of the Giara. Located in the heart of Sardinia, it offers numerous archaeological and nuragic sites, some of which are present in the Giara Park. The small villages of Collina and Sanluri are full of houses in local stone and bricks with classic Sardinian tiles, as well as numerous religious buildings in Baroque and Renaissance styles. Ogliastra includes two capitals: Ogliastra and Lanusei. Both boast numerous places of interest, such as the eighteenth-nineteenth-century palaces of Tortoli, the Bishop’s Palace and the Cathedral of Sant’Andrea, the main place of Catholic worship in the historic center. Among the archaeological sites of greatest interest we find the Nuraghe, very ancient constructions, many of which can be visited such as the well preserved Serbissi complex.
