Sybaris was an important city of Magna Graecia. The city was founded in 720 BC by Achaean and Troezenian settlers. Sybaris amassed great wealth thanks to its fertile land and busy port. Its inhabitants became famous among the Greeks for their hedonism, feasts, and excesses, to the extent that 'sybarite' and 'sybaritic' have become bywords for opulence, luxury and outrageous pleasure-seeking.
In 510/09 BC the city was subjugated by its neighbor Kroton and its population driven out. Sybaris became a dependent ally of Kroton, but Kroton again besieged the city in 476/5 BC, probably resulting in another victory for Kroton. Two attempts to reoccupy the city failed around 452/1 BC and 446/5 BC when the remaining Sybarites were again expelled by the Krotoniates. After a call for help the Sybarites reoccupied their city later in 446/5 BC with the assistance of new settlers from Athens and other cities in the Peloponnese. This coexistence did not last long: the Sybarites got into a conflict with the new colonists and were ousted for the last time in the summer of 445 BC. In sum, the city saw a total of five periods of occupation separated by expulsion. The new settlers then proceeded to found the city of Thurii in 444/3 BC, a new colony which was built partially on top of the site of Sybaris. The surviving Sybarites founded Sybaris on the Traeis.
The ruins of Sybaris and Thurii became forgotten as they were buried by sediment from the Crati river over time. The ruins were rediscovered and excavated in the 1960s by Donald Freeman Brown. Today they can be found southeast of Sibari, a frazione in the comune of Cassano allo Ionio.
References:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
