The Priamar Fortress is a fortress occupying the hill with the same name above the port of Savona. The fortress was built in 1542 by the Republic of Genoa on a promontory where in medieval times was the nucleus of Savona, by design of architect Giovanni Maria Olgiati. However, traces of pre-Roman, Roman and Byzantine presences in the site have been excavated in the past centuries, and are now on display in Savona's Archaeological Museum.
In the 17th century the fortress received bastions designed by the Spanish Royal engineer Domenico Sirena, and in the 18th century were added the commissar's, officers' and Sibilla palaces. In order to create space for the new structures, edifices of the medieval Savona, including its cathedral (built in the 9th century over a pagan temple), were demolished.
In 1746, in the course of the War of Austrian Succession, it was stormed by the Piedmontese grenadiers. In 1820, after the annexion of Liguria to Piedmont, it became a prison. During the Risorgimento, Italian patriot Giuseppe Mazzini was jailed in the Priamar Fortress.
The fortress, which could house up to 500 prisoners, remained Italy's main military prison until 1903, when its role was taken by the castle of Gaeta.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
