The origins of Puente del Congosto Castle dates from the 12th and 13th centuries. It was built for defensive reasons, to control the route which connected Ciudad Rodrigo with Avila.
In 1393, Enrique III granted the manor of the Puente del Congosto to Gil Gonzalez Davila, which rebuilt the castle, which would be Posada Real. The Duke of Alba bought the castle to the Emperor Carlos in 1539, adding to the rectangular tower the large cube gives to the building most uniqueness.
The castle is in a good state of conservation. It is made up of an outer enclosure and an inner fortification formed by a great rectangular keep with a second tower build against it.
The outer enclosure is an irregular rubblework hexagon, reinforced in the corners by granite ashlars. Because it is more vulnerable than the others, the western curtain wall of the outer enclosure is extra protected with a small tower in its center. The gate is situated in the northern wall and is protected by another wall. There is also a postern in the eastern wall on a higher floor level.The keep is made up of two great halls with brick vaults sustained by arcs of ashlar masonry. In the lower hall, on a height of about 3 meters in the western wall, is the entrance to the spiral staircase that leads to the upper hall. In the eastern wall is a little window. The top of the keep was originally crenelated.The ground floor level of the second tower is only the one that can be accessed from the courtyard. All the higher floor level in this tower can only be accessed through wall staircase from the keep.References:
Bamberg is located in Upper Franconia on the river Regnitz close to its confluence with the river Main. Its historic city center is a listed UNESCO world heritage site.
Bamberg is a good example of a central European town with a basically early medieval plan and many surviving ecclesiastical and secular buildings of the medieval period. When Henry II, Duke of Bavaria, became King of Germany in 1007 he made Bamberg the seat of a bishopric, intended to become a 'second Rome'. Of particular interest is the way in which the present town illustrates the link between agriculture (market gardens and vineyards) and the urban distribution centre.
From the 10th century onwards, Bamberg became an important link with the Slav peoples, especially those of Poland and Pomerania. During its period of greatest prosperity, from the 12th century onwards, the architecture of this town strongly influenced northern Germany and Hungary. In the late 18th century Bamberg was the centre of the Enlightenment in southern Germany, with eminent philosophers and writers such as Georg Wilhelm Friedrich Hegel and E.T.A. Hoffmann living there.
Bamberg extends over seven hills, each crowned by a beautiful church. This has led to Bamberg being called the 'Franconian Rome'.
