Castello Barbarossa is an archaeological ruin and ornithological station on the island of Capri. It derives its name from the pirate and Ottoman admiral, Hayreddin, nicknamed Barbarossa ('Redbeard'), who stormed it in 1535 and destroyed it in 1544. The construction date is uncertain but it perhaps dates back to the late ninth century. From 1898, the structure, now in ruins, was owned by the Swedish psychiatrist Axel Munthewho donated it to his foundation. The surroundings, interesting for their botanical features, are home to the island's ornithological station.
The plan of the castle is quadrangular with a semicircular wall. The ruins of the highest part, as well as forming the core of the building, belong to what was once the residential area of the castle. Indeed, there is a chapel with a vaulted apse, a belfry and a cistern that was used as a warehouse Another area, offset from the chapel, retains many features, including a vaulted roof, a small partly walled embrasure, and an arched opening. Finally, there is a room with an iron-beamed roof. Built of local stone, the fort has vaulted roofs and tiled floors. The most significant architectural features are its two towers, indicating the military function of the castle. One of them, square-shaped, was built in the Swabian period, the other, however, is circular and was built in the Angevin period.

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.
