“King Carlo Emanuele (…) successfully transformed, (…) the inhospitable island into a region of fishing and trade so that it would bring wealth and well-being to the kingdom and abroad”. The inscription stands out on the southern door of the Savoy fortress: it was the first masonry building (1738) of the then-emerging Carloforte, a village built on a natural acropolis. The small fort was built as a guardhouse and meeting site and later became a place of imprisonment. Following its renovation, it currently accommodates the civic museum, known as the Museum of the Sea. Inside it, you will find the story of a Ligurian community that moved from Tabarka (in Tunisia) to the Sulcis island of San Pietro, which can now be reached in 40 minutes by ferry from Calasetta and Portoscuso.
