Although only the Great Pyramid of Giza remains of the Seven Wonders of the Ancient World, the modern world can surely boast with a number of memorable architectural monuments. Eiffel Tower, Statue of Liberty, Burj Khalifa… the list could go on and on.

And while we can travel to most of them and see their magnificence and beauty surrounded by contemporary structures ourselves, there is something deeply admirable about the process of construction. Perhaps it’s the progress that draws our eyes, the ability to pinpoint growing elements in a building. Or maybe it’s their potential, the uncertainty of what they will look like, what effect they will have on the landscape, what future does it hold for people and how long would it survive? The wondrous possibility of our modern architectural triumphs turn into Great Pyramids of the future. Or maybe snaps of famous buildings being constructed simply fill out curiosity and adds a different dimension to an already familiar puzzle.

#1 Golden Gate Bridge In San Francisco, California

Yet another signature structure in this list, the picturesque Golden Gate Bridge that we cannot imagine San Francisco without. It spans across the Golden Gate, the strait connecting San Francisco Bay and the Pacific Ocean and is 8,981 ft (2,737.4 m) long. The construction of the suspension bridge started on January 5, 1933, with architect Irving Morrow at the helm and engineering design by Joseph Strauss, and Charles Ellis. The production cost was more than $35 million ($493 million in 2016 dollars), though the bridge was finished ahead of schedule and $1.3 million under budget (equivalent to $23.8 million today). It was finished in 4 years and took 11 construction workers’ lives.

#2 Eiffel Tower In Paris, France

The Eiffel Tower is one of the most iconic structures in the world, a must-see when visiting France. It’s so fundamental to the scenery of Paris that it’s hard to imagine that there were times it wasn’t there. But before 1887, when the construction of the tower started, there was only a debate over how to celebrate the centennial of the French Revolution and a suitable centerpiece for the proposed 1889 Exposition Universelle. Maurice Koechlin and Émile Nouguier, two senior engineers working for the Compagnie des Établissements Eiffel are attributed with the design of the tower. However, as hard as it is to imagine, there were many people who thought the design to be hideous and many even protested the construction, especially artists. Nonetheless, the tower was finished on 15 March 1889, with 300 on-site workers, 1 fatality and around 10k tons of metal. Looming at 300m the Eiffel Tower was the tallest structure in the world at that time.

#3 Statue Of Liberty In New York City, U.S.

The icon of freedom from oppression, unity, and friendship between two nations, the Statue of Liberty was a gift from the people of France to the people of the United States. The friendship between two nations established during the American Revolution was turned into a symbol by Frédéric Auguste Bartholdi who sculpted the statue and obtained a U.S. patent for the structure. The statue took years to build, starting with the right arm in 1875, being assembled and disassembled in France, shipped to the US, assembled once more and finally officially dedicated and unveiled on October 28, 1886. It took a lot of effort, fundraising and hard work (crews, reportedly, worked round the clock, seven days a week, for nine years to finish the statue), but it became one of the best known symbols in the country, if not the world. The Statue of Liberty is 151 feet 1 inch (46 meters) tall, making it 305 feet 1 inch (93 meters) tall with the pedestal.

#4 Lincoln Memorial In Washington, D.C., U.S.

President Abraham Lincoln was definitely a memorable figure in his lifetime and, arguably, even more after his death. In 1868, 3 years after Lincoln’s assassination, Lot Flannery erected a statue in front of the District of Columbia City Hall as a public memorial for the former president, which sparked public interest in a national memorial. Though despite passing (and rejecting) a great number of bills, the Lincoln Memorial that we know today only started to take its roots on February 12, 1914, when the actual construction began. With $300,000 of funds, the memorial was finished in 1922 with Henry Bacon as the architect and Daniel Chester French as the sculptor for the project. The entire memorial takes 27,336 square feet (2,539.6 m2) of space, while the exterior ‘temple’ measures 189.7 by 118.5 feet (57.8 by 36.1 m) and is 99 feet (30 m) tall. It was built in the classic Greek fashion with signature columns and friezes. Lincoln statue is 19 feet (5.8 m) and is made of Georgia white marble weighing 175 short tons (159 t) and it had to be shipped in twenty-eight pieces.

#5 Empire State Building In New York City, U.s.

Yet another iconic structure from the Big Apple that one can hardly imagine the city’s landscape without. The Empire State Buildingis a 102-story Art Deco skyscraper that looms at 1,454 ft (443.2 m) and is in most of the ‘must see in New York City’ lists. It took a long time to plan and design as the building plans went through 15 different versions before the current plan was approved. The construction work began on October 1, 1929 with the demolition of the old Waldorf–Astoria hotel. The construction concluded on April 11, 1931, costing $40,948,900 ($534 million in 2016 dollars). The building process was captured by Lewis Hine, who would climb up and dangle from the building together with the workers to provide insight into the process and daily lives of every day workers. The photos captured the public’s eye as they were fascinated by the sheer height the people worked at.

#6 Sydney Opera House In Sydney, Australia

When the Director of the NSW State Conservatorium of Music, Eugene Goossens insisted on having a suitable venue for large theatrical productions back in the 1940s, no one had a single idea that the project that followed would become one of the most prominent buildings in the world. The construction of Sydney Opera House started in 1959 with the demolishing of Fort Macquarie Tram Depot that occupied the site. The design was prepared by a Danish architect Jørn Utzon who won the international competition for the project, beating 233 entries, representing architects from 32 countries. The construction was split into three stages, podium, roof and interior and was finished by 1973. The structure cost $102 million (equivalent to ~A$927 million in 2016) and looms at 65 m (213 ft).

#7 Manhattan Bridge In New York City, U.S.

Yet another suspension bridge and a structure in New York City, the Manhattan Bridge is 1,470 ft (448 m) long, 336 ft (102 m) high bridge that connects Lower Manhattan with Downtown Brooklyn. The construction began in 1901 with towers being erected first. The remainder of the bridge was completed by 1912 and required 30,000 tons of steel, and around $22 million. Despite needing numerous repairs throughout the years, the bridge still remains one of the most picturesque parts of the city, with the triumphal arch and colonnade decorating the Manhattan entrance.

#8 Tower Bridge In London, The United Kingdom

ust as the Eiffel Tower in Paris or the Statue of Liberty in New York, one could hardly imagine London without its iconic Tower Bridge. Back in the 19th century, when people ran into the problem of needing a bridge downstream of London Bridge but also not wanting to cut off access by sailing ships to the port facilities in the Pool of London, between London Bridge and the Tower of London. A comittee was formed in 1877 to resolve the issue and it ended up picking Sir John Wolfe Barry for engineer and Sir Horace Jones as architect to build a new bridge. The construction began in 1886 and finished 8 years later, with 432 construction workers, over 70,000 tons of concrete, over 11,000 tons of steel and a cost of £1,184,000 (equivalent to £132 million in 2018). The bridge is 213 ft (65 m) tall and stretches across the river to 270 ft (82.3 m).

#9 World Trade Center In New York City, U.S.

World Trade Center’s signature Twin Towers drew the world’s attention during the 9/11 attacks when the Islamic terrorist group al-Qaeda hijacked two Boeing 767 jets and rashed them into the North and South Towers within minutes of each other. The towers both collapsed within hours, taking near 3000 thousand lives, making it the single deadliest terrorist attack in human history. The construction work for the World Trade Center started on August 5, 1966. The complex was opened on April 4, 1973. The Twin Towers, the original 1 World Trade Center, at 1,368 feet (417 m); and 2 World Trade Center, at 1,362 feet (415.1 m), were the tallest buildings in the world at the time of their completion.

#10 Burj Khalifa In Dubai, United Arab Emirates

World’s tallest building, The Burj Khalifa is a massive skyscraper in Dubai, United Arab Emirates that reaches an impressive 828 m (2,717 ft) height. Construction of the building commenced on 6 January 2004 and concluded on 1 October 2009. It was built as part of a larger development called Downtown Dubai and cost US$1.5 billion to complete. While originally named Burj Dubai, it was later renamed to Burj Khalifa in honor of the president of the United Arab Emirates, Khalifa bin Zayed Al Nahyan.

#11 Mount Rushmore Models

Perhaps one of the most iconic monuments in the USA, Mount Rushmore National Memorial depicts heads of Presidents George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln carved into the granite face of Mount Rushmore in the Black Hills in Keystone, South Dakota. It is reported to attract more than two million visitors annually. Historian Doane Robinson wanted to promote tourism in South Dakota so he came up with an idea for a memorial and persuaded sculptor Gutzon Borglum to model the sculptures. After the project was approved by Congress, the carving started in 1927 and ended in 1941 without a single fatality.
