Bar Hill Roman Fort lies near the top of Bar Hill, in a strategic location looking north over the Kelvin Valley to the Campsie Fells. It was built as one of the forts housing troops manning the Antonine Wall, which was for a while the north-west frontier of a Roman Empire. Along with Rough Castle near Falkirk, it is one of the two best locations along the Antonine Wall to gain a real impression of what the wall was like, and what life would have been like for the troops manning it.
The Antonine Wall was built from AD 142 to 144 and ran for 60km from Bo'ness on the River Forth to Old Kilpatrick on the River Clyde. Like the better known Hadrian's Wall to the south, it formed a solid barrier right across the country. A clear symbol of Roman power and authority, the wall probably served to control the movement of people and goods between the Roman-controlled area to the south and the lands to the north.
The wall was in use for around 20 years. The relatively short period of occupation and the materials used in its construction mean that it has survived less well than Hadrian's Wall: but in its day it would have been just as formidable a barrier. The wall itself was built on stone foundations, 4.3m broad, on top of which turf was laid to a height of 3.6m. The top of the wall probably carried a wooden walkway protected by a wooden breastwork.
In front of the wall a ditch was dug to a depth of 3.6m and a breadth of up to 12m, with the spoil forming a mound along the north edge of the ditch. And in some places, as can be seen at Rough Castle, the wall was additionally protected by pits containing stakes. A little way to the south of the line of the wall ran a Roman Road, the Military Way, which was some 6m wide. At intervals of around 2 miles a fort was built to house the troops manning the wall. There were probably 19 of these along the wall, though only 17 have been found on the ground.
Bar Hill Roman Fort was unusual in that its north wall does not form part of the Antonine Wall itself. Instead, while the Antonine Wall follows a course a little way down the shoulder of the north side of Bar Hill, the fort is draped over the summit of the hill and built on its upper slopes. The Military Way passed between the fort and the wall.
It has to be said that the Antonine Wall as it runs along the flank of Bar Hill is not as well preserved as it is at Rough Castle, though here you do get more of a sense of how it would have commanded the landscape. Perhaps the best reason to visit is that, after excavations between 1979 and 1982, the plan and some lower levels of stonework of some of the buildings were left on view.
The largest visible building is the headquarters, placed on the south-facing slope of the hill, presumably with an eye to maximising sunlight. But in many ways the most impressive building is the bathhouse, which originally stood close to the north wall of the fort on the fairly steep northern slope of the hill. Here enough remains on the ground to give an impression of the function of what, for many who lived here, would have been one of the most essential buildings in the fort.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.
