The construction of the Teutonic Castle in Dzierzgoń began in 1248, as ordered by the national champion Heinrich von Wida. At its location there was chosen towering hill over the area, where previously was a fortified city of Prussia, to protect the settlement lying at its feet. The fort was the seat of the Commander of Dzierzgoń, who also held the function of the Quatermaster (Obersttrappier) in the Order of the Teutonic Knights. During the heyday of the Teutonic Order Dzierzgon castle was considered to be in possession of the largest arsenal of weapons comparing to Malbork castle and the second largest Brodnica granary.
During the war of Polish and Teutonic Knights between 1409-1411, the the Dzierzgoń's monks took part in the battle of Grunwald, under the leadership of Commander Albrech von Schwarzburg. Their commander was killed in combat.
By the way of Polish forces at Malbork, the Polish King Władysław Jagiełło entered Dzierzgon and stayed at the castle. Here the King received a delegation from the Prussian towns, including Elbląg, which gave him a tribute of fidelity. In 1411 the castle was conquered by the Teutonic Knights. 42 Commanders served their role at the Dzierzgoń castle, among many of them later became the great masters of Teutonic Order. The Poles burned down the castle in Dzierzgoń twice during the war with the Teutonic Knights in 1410 and 1414. Under the peace treaty of Toruń in 1466, the castle was returned to Poland, becoming the seat of the mayor and the municipal court.References:
The Mosque–Cathedral of Córdoba, also known as the Great Mosque of Córdoba and the Mezquita is regarded as one of the most accomplished monuments of Moorish architecture.
According to a traditional account, a small Visigoth church, the Catholic Basilica of Saint Vincent of Lérins, originally stood on the site. In 784 Abd al-Rahman I ordered construction of the Great Mosque, which was considerably expanded by later Muslim rulers. The mosque underwent numerous subsequent changes: Abd al-Rahman II ordered a new minaret, while in 961 Al-Hakam II enlarged the building and enriched the Mihrab. The last of such reforms was carried out by Almanzor in 987. It was connected to the Caliph"s palace by a raised walkway, mosques within the palaces being the tradition for previous Islamic rulers – as well as Christian Kings who built their palaces adjacent to churches. The Mezquita reached its current dimensions in 987 with the completion of the outer naves and courtyard.
In 1236, Córdoba was conquered by King Ferdinand III of Castile, and the centre of the mosque was converted into a Catholic cathedral. Alfonso X oversaw the construction of the Villaviciosa Chapel and the Royal Chapel within the mosque. The kings who followed added further Christian features, such as King Henry II rebuilding the chapel in the 14th century. The minaret of the mosque was also converted to the bell tower of the cathedral. It was adorned with Santiago de Compostela"s captured cathedral bells. Following a windstorm in 1589, the former minaret was further reinforced by encasing it within a new structure.
The most significant alteration was the building of a Renaissance cathedral nave in the middle of the expansive structure. The insertion was constructed by permission of Charles V, king of Castile and Aragon. Artisans and architects continued to add to the existing structure until the late 18th century.
The building"s floor plan is seen to be parallel to some of the earliest mosques built from the very beginning of Islam. It had a rectangular prayer hall with aisles arranged perpendicular to the qibla, the direction towards which Muslims pray. The prayer hall was large and flat, with timber ceilings held up by arches of horseshoe-like appearance.
In planning the mosque, the architects incorporated a number of Roman columns with choice capitals. Some of the columns were already in the Gothic structure; others were sent from various regions of Iberia as presents from the governors of provinces. Ivory, jasper, porphyry, gold, silver, copper, and brass were used in the decorations. Marvellous mosaics and azulejos were designed. Later, the immense temple embodied all the styles of Morisco architecture into one composition.
The building is most notable for its arcaded hypostyle hall, with 856 columns of jasper, onyx, marble, granite and porphyry. These were made from pieces of the Roman temple that had occupied the site previously, as well as other Roman buildings, such as the Mérida amphitheatre. The double arches were an innovation, permitting higher ceilings than would otherwise be possible with relatively low columns. The double arches consist of a lower horseshoe arch and an upper semi-circular arch.
