The Pont du Gard is an ancient Roman aqueduct that crosses the Gardon River in southern France. The bridge is part of the Nîmes aqueduct, a 50-kilometre system built in the first century AD to carry water from a spring at Uzès to the Roman colony of Nemausus (Nîmes). Because of the uneven terrain between the two points, the mostly underground aqueduct followed a long, winding route that called for a bridge across the gorge of the Gardon River. The Pont du Gard is the highest of all elevated Roman aqueducts, and, along with the Aqueduct of Segovia, one of the best preserved. It was added to UNESCO's list of World Heritage Sites in 1985 because of its historical importance.
The bridge has three tiers of arches, standing 48.8m high. The whole aqueduct descends in height by only 17 m over its entire length, while the bridge descends by a mere 2.5 centimetres which is indicative of the great precision that Roman engineers were able to achieve, using only simple technology. The aqueduct formerly carried an estimated 200,000 m3 of water a day to the fountains, baths and homes of the citizens of Nîmes. It continued to be used possibly until the 6th century, with some parts used for significantly longer, but lack of maintenance after the 4th century meant that it became increasingly clogged by mineral deposits and debris that eventually choked off the flow of water.
After the collapse of the Roman Empire and the aqueduct's fall into disuse, the Pont du Gard remained largely intact, due to the importance of its secondary function, as a toll bridge. For centuries the local lords and bishops were responsible for its upkeep, in exchange for the right to levy tolls on travellers using it to cross the river, although some of its stones were looted and serious damage was inflicted on it in the 17th century. It attracted increasing attention starting in the 18th century, and became an important tourist destination. It underwent a series of renovations between the 18th and 21st centuries, commissioned by the local authorities and the French state, that culminated in 2000 with the opening of a new visitor centre and the removal of traffic and buildings from the bridge and the area immediately around it. Today it is one of France's most popular tourist attractions, and has attracted the attention of a succession of literary and artistic visitors.References:
Castle Rushen is located in the Isle of Man"s historic capital, Castletown. The castle is amongst the best examples of medieval castles in the British Isles, and is still in use as a court house, museum and educational centre.
The exact date of castle is unknown, although construction is thought to have taken place during the reigns of the late 12th century and early 13th century rulers of the Isle of Man – the Kings of Mann and the Isles. The original Castle Rushen consisted of a central square stone tower, or keep. The site was also fortified to guard the entrance to the Silver Burn. From its early beginnings, the castle was continually developed by successive rulers of Mann between the 13th and 16th century. The limestone walls dominated much of the surrounding landscape, serving as a point of dominance for the various rulers of the Isle of Man. By 1313, the original keep had been reinforced with towers to the west and south. In the 14th century, an east tower, gatehouses, and curtain wall were added.
After several more changes of hands the English and their supporters eventually prevailed. The English king Edward I Longshanks claimed that the island had belonged to the Kings of England for generations and he was merely reasserting their rightful claim to the Isle of Man.
The 18th century saw the castle in steady decay. By the end of the century it was converted into a prison. Even though the castle was in continuous use as a prison, the decline continued until the turn of the 20th century, when it was restored under the oversight of the Lieutenant Governor, George Somerset, 3rd Baron Raglan. Following the restoration work, and the completion of the purpose-built Victoria Road Prison in 1891, the castle was transferred from the British Crown to the Isle of Man Government in 1929.
Today it is run as a museum by Manx National Heritage, depicting the history of the Kings and Lords of Mann. Most rooms are open to the public during the opening season (March to October), and all open rooms have signs telling their stories. The exhibitions include a working medieval kitchen where authentic period food is prepared on special occasions and re-enactments of various aspects of medieval life are held on a regular basis, with particular emphasis on educating the local children about their history. Archaeological finds made during excavations in the 1980s are displayed and used as learning tools for visitors.
