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:
The Seaplane Harbour is the newest and one of the most exciting museums in Tallinn. It tells stories about the Estonian maritime and military history. The museum’s display, that comprises of more than a couple of hundred large exhibits, revitalizes the colourful history of Estonia.
British built submarine Lembit weighing 600 tones is the centrepiece of the new museum. Built in 1936 for the Estonian navy, Lembit served in the World War II under the Soviet flag. It remained in service for 75 years being the oldest submarine in the World still in use until it was hauled ashore in 2011. Despite its long history, Lembit is still in an excellent condition offering a glimpse of the 1930s art of technology.
Another exciting attraction is a full-scale replica of Short Type 184, a British pre-World War II seaplane, which was also used by the Estonian armed forces. Short Type 184 has earned its place in military history by being the first aircraft ever to attack an enemy’s ship with an air-launched torpedo. Since none of the original seaplanes have survived, the replica in Seaplane Harbour is the only full-size representation of the aircraft in the whole World.
Simulators mimicking a flight above Tallinn, around-the-world journey in the yellow submarine, navigating on the Tallinn bay make this museum heaven for kids or adventurous adults.
Seaplane Harbour operates in architecturally unique hangars built almost a century ago, in 1916 and 1917, as a part of Peter the Great sea fortress. These hangars are the World’s first reinforced concrete shell structures of such a great size. Charles Lindbergh, the man who performed the first solo flight across the Atlantic Ocean, landed here in 1930s.
On the outdoor area visitors can tour a collection of historic ships, including the Suur Tõll, Europe's largest steam-powered icebreaker.
