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.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
