Founded in the 8th century BC, Crotone quickly grew to become a rich and powerful city. In its early days it became the centre of one of the greatest schools of philosophy of 'Magna Graecia' ('Great Greece'), the Pythagorean school. The city's ancient origins can still be seen from the sea. Take a visit to the National Archaeological Museum of Crotone. On display, you will see treasures from the region, which not only include relics from ancient Kroton, but also artefacts that date back to prehistoric times. The main pieces in the collection are precious objects found during excavations of Hera Lacinia, an ancient Greek village on the peninsula now called Capo Colonna. The Castle of Charles V, a witness to a later period of Crotone's history, also deserves a visit. The fortress was named after the monarch who restored it in 1541, although its origins date back to the year 840, when it was built for protection against Saracen invaders.
