Great Wall of China

Great Wall of China:-


The Great Wall of China (simplified Chinese: traditional Chinese: pinyin: literally "long fortress" or simplified Chinese: traditional Chinese: pinyin: literally "The long wall of 10,000 Li is a series of stone and earthen fortifications in northern China, built originally to protect the northern borders of the Chinese Empire against intrusions by various nomadic groups such as the Xiongnu from the north and rebuilt and maintained between the 5th century BC and the 16th century. Since the 5th century BC, several walls have been built that were referred to as the Great Wall. One of the most famous is the wall built between 220–206 BC by the first Emperor of China, Qin Shi Huang. Little of that wall remains; the majority of the existing wall was built during the Ming Dynasty.

The Great Wall stretches from Shanhaiguan in the east to Lop Nur in the west, along an arc that roughly delineates the southern edge of Inner Mongolia. The most comprehensive archaeological survey, using advanced technologies, has recently concluded that the entire Great Wall, with all of its branches, stretches for 8,851.8 km (5,500.3 mi). This is made up of 6,259.6 km (3,889.5 mi) of sections of actual wall, 359.7 km (223.5 mi) of trenches and 2,232.5 km (1,387.2 mi) of natural defensive barriers such as hills and rivers.


Notable areas:-

Some of the following sections are in Beijing municipality, which were renovated and which are regularly visited by modern tourists today.

* "North Pass" of Juyongguan pass, known as the Badaling. When used by the Chinese to protect their land, this section of the wall has had many guards to defend China’s capital Beijing. Made of stone and bricks from the hills, this portion of the Great Wall is 7.8 meters (25.6 ft) high and 5 meters (16.4 ft) wide.

* "West Pass" of Jiayuguan (pass). This fort is near the western edges of the Great Wall.

* "Pass" of Shanhaiguan. This fort is near the eastern edges of the Great Wall.

* One of the most striking sections of the Ming Great Wall is where it climbs extremely steep slopes. It runs 11 kilometers (7 mi) long, ranges from 5 to 8 meters (16–26 ft) in height, and 6 meters (19.7 ft) across the bottom, narrowing up to 5 meters (16.4 ft) across the top. Wangjinglou is one of Jinshanling's 67 watchtowers, 980 meters (3,215 ft) above sea level.

* South East of Jinshanling, is the Mutianyu Great Wall which winds along lofty, cragged mountains from the southeast to the northwest for approximately 2.25 kilometers (about 1.3 miles). It is connected with Juyongguan Pass to the west and Gubeikou to the east.

* 25 km west of the Liao Tian Ling stands apart of Great Wall which is only 2~3 stories high. According to the records of Lin Tian, the wall was not only extremely short compared to others, but it appears to be silver. Archeologists explain that the wall appears to be silver because the stone they used were from Shan Xi, where many mines are found. The stone contains extremely high metal in it causing it to appear silver. However, due to years of decay of the Great Wall, it is hard to see the silver part of the wall today.


Another notable section lies near the eastern extremity of the wall, where the first pass of the Great Wall was built on the Shanhaiguan (known as the “Number One Pass Under Heaven”), the first mountain the Great Wall climbs. Jia Shan is also here, as is the Jiumenkou, which is the only portion of the wall that was built as a bridge.

Taj Mahal

The Taj Mahal is a mausoleum located in Agra, India, built by Mughal emperor Shah Jahan in memory of his favorite wife, Mumtaz Mahal. Taj Mahal means "crown of buildings" in Urdu.


The Taj Mahal (also "the Taj") is considered the finest example of Mughal architecture, a style that combines elements from Islamic, Indian and Persian architectural styles.

In 1983, the Taj Mahal became a UNESCO World Heritage Site. In a project that attempted to update the Seven Wonders of the Ancient World, popularity poll was led by Canadian-Swiss Bernard Weber and organized by the Swiss-based, government-controlled New7Wonders Foundation considered Taj Mahal to be one of the present new seven wonders of the world.


While the white domed marble mausoleum is its most familiar component, the Taj Mahal is actually an integrated complex of structures. Building began around 1632 and was completed around 1653, and employed thousands of artisans and craftsmen. The construction of the Taj Mahal was entrusted to a board of architects under imperial supervision including Abd ul-Karim Ma'mur Khan, Makramat Khan, and Ustad Ahmad Lahauri. Lahauri is generally considered to be the principal designer.





Construction:-

The Taj Mahal was built on a parcel of land to the south of the walled city of Agra. Shah Jahan presented Maharajah Jai Singh with a large palace in the center of Agra in exchange for the land. An area of roughly three acres was excavated, filled with dirt to reduce seepage, and leveled at 50 metres (160 ft) above riverbank. In the tomb area, wells were dug and filled with stone and rubble to form the footings of the tomb. Instead of lashed bamboo, workmen constructed a colossal brick scaffold that mirrored the tomb. The scaffold was so enormous that foremen estimated it would take years to dismantle. According to the legend, Shah Jahan decreed that anyone could keep the bricks taken from the scaffold, and thus it was dismantled by peasants overnight. A fifteen kilometer (9.3 mi) tamped-earth ramp was built to transport marble and materials to the construction site and teams of twenty or thirty oxen pulled the blocks on specially constructed wagons. An elaborate post-and-beam pulley system was used to raise the blocks into desired position. Water was drawn from the river by a series of purs, an animal-powered rope and bucket mechanism, into a large storage tank and raised to a large distribution tank. It was passed into three subsidiary tanks, from which it was piped to the complex.



The plinth and tomb took roughly 12 years to complete. The remaining parts of the complex took an additional 10 years and were completed in order of minarets, mosque and jawab, and gateway. Since the complex was built in stages, discrepancies exist in completion dates due to differing opinions on "completion". For example, the mausoleum itself was essentially complete by 1643, but work continued on the rest of the complex. Estimates of the cost of construction vary due to difficulties in estimating costs across time. The total cost has been estimated to be about 32 million Rupees at that time.



The Taj Mahal was constructed using materials from all over India and Asia and over 1,000 elephants were used to transport building materials. The translucent white marble was brought from Makrana, Rajasthan, the jasper from Punjab, jade and crystal from China. The turquoise was from Tibet and the Lapis lazuli from Afghanistan, while the sapphire came from Sri Lanka and the carnelian from Arabia. In all, twenty eight types of precious and semi-precious stones were inlaid into the white marble.

A labour force of twenty thousand workers was recruited across northern India. Sculptors from Bukhara, calligraphers from Syria and Persia, inlayers from southern India, stonecutters from Baluchistan, a specialist in building turrets, another who carved only marble flowers were part of the thirty-seven men who formed the creative unit. Some of the builders involved in construction of Taj Mahal are:



* Ismail Afandi (a.ka. Ismail Khan) of the Ottoman Empire — designer of the main dome.

* Ustad Isa and Isa Muhammad Effendi of Persia — trained by Koca Mimar Sinan Agha of the Ottoman Empire and frequently credited with a key role in the architectural design.

* 'Puru' from Benarus, Persia — has been mentioned as a supervising architect.

* Qazim Khan, a native of Lahore - cast the solid gold finial.

* Chiranjilal, a lapidary from Delhi — the chief sculptor and mosaicist.

* Amanat Khan from Shiraz, Iran — the chief calligrapher.

* Muhammad Hanif — a supervisor of masons.

* Mir Abdul Karim and Mukkarimat Khan of Shiraz — handled finances and management of daily production.

History:-

Soon after the Taj Mahal's completion, Shah Jahan was deposed by his son Aurangzeb and put under house arrest at nearby Agra Fort. Upon Shah Jahan's death, Aurangzeb buried him in the mausoleum next to his wife.



By the late 19th century, parts of the buildings had fallen badly into disrepair. During the time of the Indian rebellion of 1857, the Taj Mahal was defaced by British soldiers and government officials, who chiseled out precious stones and lapis lazuli from its walls. At the end of the 19th century, British viceroy Lord Curzon ordered a sweeping restoration project, which was completed in 1908. He also commissioned the large lamp in the interior chamber, modeled after one in a Cairo mosque. During this time the garden was remodeled with British-style lawns that are still in place today.



Colosseum

The Colosseum or Roman Coliseum, originally the Flavian Amphitheatre (Latin: AmphitheatrumFlavium, Italian Anfiteatro Flavio or Colosseo), is an elliptical amphitheatre in the center of the city of Rome, Italy, the largest ever built in the Roman Empire. It is considered one of the greatest works of Roman architecture and Roman engineering.

Occupying a site just east of the Roman Forum, its construction started between 70 and 72 AD under the emperor Vespasian and was completed in 80 AD under Titus, with further modifications being made during Domitian's reign (81–96). The name "Amphitheatrum Flavium" derives from both Vespasian's and Titus's family name (Flavius, from the gens Flavia).



Capable of seating 50,000 spectators, the Colosseum was used for gladiatorial contests and public spectacles. As well as the gladiatorial games, other public spectacles were held there, such as mock sea battles, animal hunts, executions, re-enactments of famous battles, and dramas based on Classical mythology. The building ceased to be used for entertainment in the early medieval era. It was later reused for such purposes as housing, workshops, quarters for a religious order, a fortress, a quarry, and a Christian shrine.



Although in the 21st century it stays partially ruined because of damage caused by devastating earthquakes and stone-robbers, the Colosseum is an iconic symbol of Imperial Rome. It is one of Rome's most popular tourist attractions and still has close connections with the Roman Catholic Church, as each Good Friday the Pope leads a torchlit "Way of the Cross" procession that starts in the area around the Colosseum.



Todays:-



The Colosseum today is now a major tourist attraction in Rome with thousands of tourists each year paying to view the interior arena, though entrance for EU citizens is partially subsidised, and under-18 and over-65 EU citizens' entrances are free. There is now a museum dedicated to Eros located in the upper floor of the outer wall of the building. Part of the arena floor has been re-floored. Beneath the Colosseum, a network of subterranean passageways once used to transport wild animals and gladiators to the arena opened to the public in summer 2010.



The Colosseum is also the site of Roman Catholic ceremonies in the 20th and 21st centuries. For instance, Pope Benedict XVI leads the Stations of the Cross called the Scriptural Way of the Cross (which calls for more meditation) at the Colosseum on Good Fridays.
