The Admiral's Bridge (Ponte dell'Ammiraglio) is a medieval bridge of Palermo. It was built over the Oreto River during the era of the Norman Sicily by the ammiratus ammiratorum George of Antioch. In 2015, it became a UNESCO World Heritage Site as part of a series of nine civil and religious structures inscribed as Arab-Norman Palermo and the Cathedral Churches of Cefalù and Monreale.
According to a legend, the bridge is situated in the place where the Archangel Michael appeared to the Norman Count Roger I of Sicily helping him to conquer Palermo, at that time an Islamic bastion.It was completed in 1131, a year after the incoronation of Roger II as first King of Sicily. The construction was supervised by the admiral George of Antioch, the most powerful man of the Kingdom after Roger II. The bridge had the function to connect the capital to the royal gardens located across the Oreto River, like the Favara Park. Even now, the structure represents a symbol connecting the historic centre to the peripheral quarter of Brancaccio.
Since then, the bridge has been repeatedly damaged by the Oreto's overflowes. For this reason, as long ago as 1775, an attempt was made to divert the river. However, it was not until 1938 that the Oreto was definitely diverted and canalized. Seven years before, in February 1931, Palermo had been plagued by a terrible flood.
Thanks to its strategic position, on 27 May 1860, the bridge was the place of a famous battle between the Red Shirts of Giuseppe Garibaldi and the army of the House of Bourbon-Two Sicilies during the Expedition of the Thousand.
The Amphitheatre of the Three Gauls was part of the federal sanctuary of the three Gauls dedicated to the cult of Rome and Augustus celebrated by the 60 Gallic tribes when they gathered at Lugdunum (Lyon). The amphitheatre was built at the foot of the La Croix-Rousse hill at what was then the confluence of the Rhône and Saône.
Excavations have revealed a basement of three elliptical walls linked by cross-walls and a channel surrounding the oval central arena. The arena was slightly sloped, with the building"s south part supported by a now-vanished vault. The arena"s dimensions are 67,6m by 42m. This phase of the amphitheatre housed games which accompanied the imperial cult, with its low capacity (1,800 seats) being enough for delegations from the 60 Gallic tribes.
The amphitheatre was expanded at the start of the 2nd century. Two galleries were added around the old amphitheatre, raising its width from 25 metres to 105 metres and its capacity to about 20,000 seats. In so doing it made it a building open to the whole population of Lugdunum and its environs.
