Starigrad Fortress was built during the Croatian–Ottoman wars (15th century) as a primary defence against the Ottoman Empire. The precipitous fortification is sited on a 262 m ridge above the town Omiš. In the event of attack, its purpose was to provide refuge for local people and be a stronghold where they could retreat to and resist the Turks.
As the stone fort's defensive strength is derived from the elevation at which it was built, it is a rudimentary defensive structure. A two-storey square tower stands at its highest point, serving as both a lookout post and keep. A simple bastion stands at the opposite end of the fort to cover the approach path and the ridge line. It has an outer barbican to defend the fort's narrow entrance gateway and the gorge below the fort. The walls, which are about 1 m thick, are made from locally quarried limestone. They enclose an inner bailey that is separated into two distinct levels by the difference in the site's natural rock height. Access between the levels is via a small stone stairway that was once protected by a stone wall and gateway. In event of attack, the fortification's design permits the defenders to fall back to higher ground as each level falls.

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.
