The Castle of Eger is historically known for repelling the Turkish attack in 1552 during the Siege of Eger. During the Mongol invasion in 1241, this castle was ruined, and the bishop of Eger moved it to a rocky hill in the city of Eger. On the hill, a new castle was built, and it developed rapidly. In 1470 a Gothic palace was built. In 1552, a Turkish army of 35,000-40,000 soldiers attacked the castle which had 2,100-2,300 defenders. The siege failed as the Turks suffered heavy casualties. A total of 1,700 of the defenders survived. After that Turks besieged the castle again in 1596, resulting in a Turkish victory. In 1701, the Austrians exploded half of the castle (the Külső vár).
Archaeological excavations only started in 1925 and the castle was used by the army as barracks until 1957. Today there are several museums in the castle.

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.
