1. Egyptian Pyramids
The Egyptian pyramids are ancient pyramid-shaped masonry structures located in Egypt.
There are 138 pyramids discovered in Egypt as of 2008. Most were built as tombs for the country's Pharaohs and their consorts during the Old and Middle Kingdom periods.
The earliest known Egyptian pyramids are found at Saqqara, northwest of Memphis. The earliest among these is the Pyramid of Djoser (constructed 2630 BCE–2611 BCE) which was built during the third dynasty. This pyramid and its surrounding complex were designed by the architect Imhotep, and are generally considered to be the world's oldest monumental structures constructed of dressed masonry.
The most famous Egyptian pyramids are those found at Giza, on the outskirts of Cairo. Several of the Giza pyramids are counted among the largest structures ever built.
The Pyramid of Khufu at Giza is the largest Egyptian pyramid. It is the only one of the Seven Wonders of the Ancient World still in existence.
2. Hagia Sophia at Istanbul
Hagia Sophia is a former Orthodox patriarchal basilica, later a mosque and now a museum in Istanbul, Turkey. From the date of its dedication in 360 until 1453, it served as the cathedral of Constantinople, except between 1204 and 1261, when it was the cathedral of the Latin Empire. The building was a mosque from 29 May 1453 until 1934, when it was secularized. It was opened as a museum on 1 February 1935.
The Church was dedicated to the Logos, the second Person of the Holy Trinity. [2] This is confirmed by its Dedication's Feast, which took place on December 25th, the anniversary of the Incarnation of the Logos in Christ.
Famous in particular for its massive dome, it is considered the epitome of Byzantine architecture and is said to have "changed the history of architecture." It was the largest cathedral in the world for nearly a thousand years, until Seville Cathedral was completed in 1520. The current building was originally constructed as a church between 532 and 537 on the orders of the Byzantine Emperor Justinian and was the third Church of the Holy Wisdom to occupy the site, the previous two having both been destroyed by rioters. It was designed by Isidore of Miletus, a physicist, and Anthemius of Tralles, a mathematician.
The church contained a large collection of holy relics and featured, among other things, a 49 foot (15 m) silver iconostasis. It was the seat of the Patriarch of Constantinople and the religious focal point of the Eastern Orthodox Church for nearly one thousand years. It is the church in which Cardinal Humbert in 1054 excommunicated Michael I Cerularius - which is commonly considered the start of the Great Schism.
In 1453, Constantinople was conquered by the Ottoman Turks and Sultan Mehmed II ordered the building to be converted into a mosque. The bells, altar, iconostasis, and sacrificial vessels were removed and many of the mosaics were eventually plastered over. The Islamic features — such as the mihrab, the minbar, and the four minarets outside — were added over the course of its history under the Ottomans. It remained as a mosque until 1935, when it was converted into a museum by the Republic of Turkey.
For almost 500 years the principal mosque of Istanbul, Hagia Sophia served as a model for many other Ottoman mosques, such as the Sultan Ahmed Mosque (Blue Mosque of Istanbul), the Şehzade Mosque, the Süleymaniye Mosque, the Rüstem Pasha Mosque and the Kılıç Ali Paşa Mosque.
Although it is sometimes referred to as Sancta Sophia, as though it were named after a saint named Sophia, Church of the Holy Wisdom of God, the church being dedicated to Jesus Christ, in Eastern Orthodox theology, the Holy Wisdom of God.
3. Leaning Tower of Pisa
The Leaning Tower of Pisa is the campanile, or freestanding bell tower, of the cathedral of the Italian city of Pisa. It is situated behind the Cathedral and is the third oldest structure in Pisa's Cathedral Square after the Cathedral and the Baptistry.
Although intended to stand vertically, the tower began leaning to the southeast soon after the onset of construction in 1173 due to a poorly laid foundation and loose substrate that has allowed the foundation to shift direction. The tower currently leans to the southwest.
The height of the tower is 55.86 m (183.27 ft) from the ground on the lowest side and 56.70 m (186.02 ft) on the highest side. The width of the walls at the base is 4.09 m (13.42 ft) and at the top 2.48 m (8.14 ft). Its weight is estimated at 14,500 metric tons (16,000 short tons). The tower has 296 or 294 steps; the seventh floor has two fewer steps on the north-facing staircase. Prior to restoration work performed between 1990 and 2001, the tower leaned at an angle of 5.5 degrees, but the tower now leans at about 3.99 degrees. This means that the top of the tower is 3.9 metres (12 ft 10 in) from where it would stand if the tower were perfectly vertical.
4. Taj Mahal
The Taj Mahal is a mausoleum located in Agra, India. It was built by Mughal emperor Shah Jahan in memory of his favorite wife, Mumtaz Mahal.
Taj Mahal is considered to be the finest example of Mughal architecture, a style that combines elements from Persian, Islamic and Indian architectural styles.
In 1983, the Taj Mahal became a UNESCO World Heritage Site. More recently it was voted by millions of people on the Internet to become one of the "New Seven Wonders of the World".
While the white domed marble mausoleum is the most familiar component of the Taj Mahal, it is actually an integrated complex of structures. The construction began around 1632 and was completed around 1653, employing 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.
5. Washington Monument
The Washington Monument is an obelisk near the west end of the National Mall in Washington, D.C., built to commemorate the first U.S. president, General George Washington. The monument, made of marble, granite, and sandstone, is both the world's tallest stone structure and the world's tallest obelisk, standing 555 feet 5⅛ inches (169.294 m). There are taller monumental columns, but they are neither all stone nor true obelisks. It is also the tallest structure in Washington D.C.. It was designed by Robert Mills, an architect of the 1840s. The actual construction of the monument began in 1848 but was not completed until 1884, almost 30 years after the architect's death. This hiatus in construction happened because of co-option by the Know Nothing party, a lack of funds, and the intervention of the American Civil War. A difference in shading of the marble, visible approximately 150 feet (46 m or 27%) up, shows where construction was halted for a number of years. The cornerstone was laid on July 4, 1848; the capstone was set on December 6, 1884, and the completed monument was dedicated on February 21, 1885. It officially opened October 9, 1888. Upon completion, it became the world's tallest structure, a title previously held by the Cologne Cathedral. The monument held this designation until 1889, when the Eiffel Tower was completed in Paris, France. The monument stands due east of the Reflecting Pool and the Lincoln Memorial.
6. Eiffel Tower
The Eiffel Tower is an 1889 iron lattice tower located on the Champ de Mars in Paris that has become both a global icon of France and one of the most recognizable structures in the world. The tallest building in Paris, it is the most-visited paid monument in the world; millions of people ascend it every year. Named for its designer, engineer Gustave Eiffel, the tower was built as the entrance arch to the 1889 World's Fair.
The tower stands 324 metres (1,063 ft) tall, about the same height as an 81-storey building. It was the tallest man-made structure in the world from its completion until the Chrysler Building in New York City was built in 1930. Not including broadcast antennas, it is the second-tallest structure in France after the 2004 Millau Viaduct.
The tower has three levels for visitors. Tickets can be purchased to ascend, by stairs or lift, to the first and second levels. The walk to the first level is over 300 steps, as is the walk from the first to the second level. The third and highest level is accessible only by lift. Both the first and second levels feature restaurants.
The tower has become the most prominent symbol of both Paris and France, often in the establishing shot of films set in the city.
7. Empire State Building
The Empire State Building is a 102-story landmark Art Deco skyscraper in New York City at the intersection of Fifth Avenue and West 34th Street. Its name is derived from the nickname for the state of New York, The Empire State. It stood as the world's tallest building for more than forty years, from its completion in 1931 until construction of the World Trade Center's North Tower was completed in 1972. Following the destruction of the World Trade Center in 2001, the Empire State Building once again became the tallest building in New York City and New York State.
The Empire State Building has been named by the American Society of Civil Engineers as one of the Seven Wonders of the Modern World. The building and its street floor interior are designated landmarks of the New York City Landmarks Preservation Commission, and confirmed by the New York City Board of Estimate. It was designated as a National Historic Landmark in 1986. In 2007, it was ranked number one on the List of America's Favorite Architecture according to the AIA. The building is owned and managed by W&H Properties.
The Empire State Building is the third tallest skyscraper in the Americas (after the Willis Tower and Trump International Hotel and Tower both in Chicago), and the 15th tallest in the world. It is also the fourth tallest freestanding structure in the Americas. The Empire State building is currently undergoing a $550 million renovation, with $120 million utilized in an effort to transform the building into a more energy efficient and eco-friendly structure.
