Colliston Castle is a 16th-century Z-plan tower house, altered and extended in the 18th and 19th centuries. Colliston was part of the lands of Arbroath Abbey from its foundation in the 12th century. On 25 July 1544, David Beaton, Abbot of Arbroath and Archbishop of St Andrews, granted the lands of Colliston, Knives, Park of Conon, and Guthrie Hill, to John Guthrie and his wife Isobel Ogilvie. Colliston was retained by the Guthries until the late 17th century, when it passed to the Gordon family. By 1820 George Chaplin was in possession of Colliston, and was succeeded by his nephew George Robertson Chaplin of Auchengray, and then George Chaplin Child Chaplin, M.D. He died in 1883, and was succeeded by Mr Peebles of Somerset House, London. It was purchased in 1920 by Major R.F.D. Bruce, whose wife continued to live there after his death. It was sold several times during the 20th century, and most recently in 2011. The house is currently available for holiday rentals. It is a category B listed building.
The original Z-plan part of the castle of Colliston bears the date 1583 (sometimes misread as 1553). It consists of a main block with two round towers projecting at opposite corners, and a stair turret rising in one of the re-entrant angles between the main block and tower. This tower, which also houses the entrance to the castle, is corbelled out at the top to form a gabled watch-chamber. The plan is similar to Claypotts Castle and is amply provided with wide splayed gun-loops and circular shot-holes for defence. The wall heads and the entire upper storey were remodelled several times and are not original. A later doorway is dated 1621, and the north and east wings were added in the 18th and 19th centuries.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.
