Construction of the Royal Castle in Poznań was probably started by Przemysł I in 1249 on hill later called Góra Zamkowa. The first building was a habitable tower made of bricks with a well inside, and the rest of the hill was surrounded by a rampart with a palisade. A small ducal residence was incorporated into the system of city walls in the late 13th century.
The son of Przemysł I, Przemysł II, hoping for reunification of Poland under his rule decided to build a larger castle, more proper for a king. In 1295 Przemysł became king of Poland, but he was assassinated a year later. The castle wasn"t finished. Work started by Przemysł was continued by a branch of the Piasts from Głogów ruling in Greater Poland, and finished before 1337. The castle served as the residence of prince Casimir, then-governor of Greater Poland.
In 1337, the Royal Castle in Poznań was the largest castle in the Polish Kingdom, modelled after the palatium of Henry I the Bearded in Legnica. The castle consisted of a tower built by Przemysł I and a huge building (63,0 m x 17,5 m) with three levels and a basement. It is uncertain whether the castle"s characteristic roof, consisting of four parts, existed at that time.
Basements served as prisons and for storage of wines, and on the ground floor there were charring rooms. Those two condignations were covered by vaults. Two higher floors probably had wooden ceilings. On the edges of first floor were representative chambers, and between them were habitual rooms. The whole second floor was occupied by achamber for 2000 guests. On the south end of the large building was a defense tower. Since the reign of Władysław I the Elbow-high the castle served as the residence of starosta generalny of Greater Poland. Later only one king, Władysław II Jagiełło, ordered some minor work in castle.
During the fire of Poznań in 1536 the castle also burned. It was rebuilt in the renaissance style by the governor of Greater Poland, Andrzej II Górka. In the next years the oldest part of castle was transformed into a kitchen. The castle was later destroyed during the Swedish invasion, sacked in 1704 by the armies of Russia and Saxony during Great Northern War, and in 1716 during Confederation of Tarnogród by the confederates. The castle was partially renovated in 1721, but it didn"t stop the devastation. The last starosta generalny, Kazimierz Raczyński, rebuilt the remains of the medieval buildings into an archive (finished in 1783). In 1804, after The Second partition of Poland, Prussians demolished the southern part of the castle, replacing it by buildings which, together with Raczyński"s archive served as the office of the local Regierungsbezirk. Later on the castle was also as a seat of the Court of Appeals and the State Archive (the castle served as an archive until 1939). During the battle for the Poznań Citadelle, in February 1945, Przemysł Hill was in line of artillery fire, and the remaining part of the castle was demolished.
In the years 1959–1964 Raczyński"s archive and part of Prussian building were rebuilt, and on base of the oldest tower stands a small pavilion called the Royal Kitchen (Kuchnia Królewska). Today the Castle holds a Museum of Utilitary Art.
In 2002, a committee for rebuilding of the castle was founded. Still extant from previous construction are two-meter-wide supports from the thirteenth and fourteenth centuries, the inner walls of the basement and the western wall from the same period, and a slightly newer eastern wall, now integrated into Raczyński"s Building. On the surviving part of the castle are three plaques: the foundation plaque of Kazimierz Raczyński from 1783, one from 1993 marking the five-hundredth anniversary of homage of Grand Master of the Teutonic Order, Johann von Tiefen, and another plaque commemorating the seven-hundredth anniversary of the coronation of Przemysł II.
On 20 December 2010, work began on the total reconstruction of the demolished parts of the castle, and meticulous restoration of the surviving buildings.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.
