Medieval castles in Northern Ireland

Carrickfergus Castle

Carrickfergus castle was built by John de Courcy in 1177 as his headquarters, after he conquered eastern Ulster in 1177 and ruled as a petty king until 1204, when he was ousted by another Norman adventurer, Hugh de Lacy. Initially de Courcy built the inner ward, a small bailey at the end of the promontory with a high polygonal curtain wall and east gate. It had several buildings, including the great hall. From ...

Dunluce Castle

Dunluce Castle is a ruined medieval castle located on the edge of a basalt outcropping in County Antrim, and is accessible via a bridge connecting it to the mainland. The castle is surrounded by extremely steep drops on either side, which may have been an important factor to the early Christians and Vikings who were drawn to this place where an early Irish fort once stood. In the 13th century, Richard Óg de Burgh, ...

Enniskillen Castle

The first Enniskillen castle was built on this site by Hugh Macguire in 1428.

Captain William Cole remodelled and refurbished the castle adding the riverside tower at the south, known as the Watergate, in 1609. The castle was remodelled as “Castle Barracks” as part of the response to a thre ...

Strangford Castle

Strangford Castle appears to be a small tower house from the late 16th century, but a blocked door of 15th century type at first floor level, seems to indicate the remodelling of an earlier tower. The current entrance, in the north-east wall, is a reconstruction, positioned by the surviving corbelled machicolation above and a socket from a draw-bar to secure the original door. The original entrance may have been on th ...

Audley"s Castle is a three-storey tower house named after its 16th century owner, John Audley. There are thousands of small stone towers similar to Audley"s Castle in the Irish countryside.

Mosque–Cathedral of Córdoba

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.

Architecture

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.
