Oeste Towers (Torres de Oeste) is located at the head of the Ría de Arousa. The towers remaining today are the ruins of Castellum Honesti. In the 9th century, King Alfonso III of Leon built the castle as a defense against Viking attacks. The two remaining towers are from this period, and have a pre-Roman style. Pre-Roman ceramics and bronze tools have been discovered at the site.
Two centuries later, King Alfonso V of Leon donates the fortress to the bishopric of Iria-Compostela, held at that moment by bishop Vestruarius. Subsequent bishops Cresconio, Diego Pelaez and Diego Gelmirez undertook the commitment to strengthen the Castle in order to protect the holy site of Santiago de Compostela. The structure of the Castle was defined in the 12th century. At that time, the enclosure of the Castle was formed by seven towers, and it was surrounded by marshes. The Castle has a 12th-century chapel built by Gelmirez to honor the apostle Saint James. The Castellum Honesti began its decline in the 15th century.

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.
