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 Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
