The Statue of Liberty was a cooperative effort between France and the United States to celebrate the two countries' long-standing relationship. The monument was sculpted by French sculptor Frederic-Auguste Bartholdi out of sheets of hammered copper, while the steel structure was built by Alexandre-Gustave Eiffel, the guy behind the famous Eiffel Tower. The Statue of Liberty was then handed to the United States and built atop an American-designed pedestal on a tiny island in Upper New York Bay, presently known as Liberty Island, and dedicated by President Grover Cleveland in 1886.

Over the years, the statue stood tall while millions of immigrants landed in America via adjacent Ellis Island; in 1986, it received major renovations in commemoration of the centennial of the Statue of Liberty.

Taj Mahal, often written Tadj Mahall, mausoleum complex in Agra, western Uttar Pradesh state, northern India. The Taj Mahal was erected by the Mughal emperor Shah Jahan (reigned 1628–58) to commemorate his wife Mumtaz Mahal ("Chosen One of the Palace"), who died in childbirth in 1631 after being the emperor's closest companion since their marriage in 1612. It is India's most renowned and generally recognized structure, and it is located in the eastern section of the city on the southern (right) bank of the Yamuna (Jumna) River. Agra Fort (Red Fort), located on the right bank of the Yamuna, lies about 1 mile (1.6 km) west of the Taj Mahal.

The Taj Mahal has been affected by India's political dynamics from time to time. Between 1984 until 2004, night viewing was prohibited because to concerns that the monument might become a target for Sikh militants. Furthermore, it has evolved to be regarded as an Indian cultural emblem. Some Hindu nationalists have sought to downplay the significance of Muslim influence in explaining the Taj Mahal's origins and architecture.

The Memorial to the Murdered Jews of Europe, also known as the Holocaust Memorial, is a monument located in Berlin, Germany. It was designed by an American architect by the name of Peter Eisenman and British Engineer Buro Happold. This memorial is dedicated to the Jewish victims of the Holocaust and is made up of 2,711 concrete slabs (stelae) across 4.7 acres of land 

Mount Rushmore National Memorial is centered on a massive sculpture carved into the granite face of Mount Rushmore (Six Grandfathers in the Black Hills near Keystone, South Dakota). 

Gutzon Borglum, a sculptor, designed the sculpture and oversaw its construction from 1927 to 1941 with the assistance of his son, Lincoln Borglum. 

The sculpture includes the 60-foot (18 m) heads of Presidents George Washington (1732–1799), Thomas Jefferson (1743–1826), Theodore Roosevelt (1858–1919), and Abraham Lincoln (1809–1865), as recommended by Borglum. 

The four presidents were chosen to represent the nation's birth, growth, development, and preservation, in that order. 

The memorial park encompasses 1,278 acres (2.00 square miles; 5.17 km2), and the actual mountain rises 5,725 feet (1,745 m) above sea level.

The Colosseum is Rome's most recognizable symbol.It is a massive structure with a nearly 2,000-year history that will transport you back in time to discover Roman Empire life.

The Colosseum's construction began in the year 72 during the reign of Vespasian and was completed in the year 80 during the reign of Titus. 

With a length of 188 meters, a width of 156 meters, and a height of 57 meters, the Colosseum became the largest Roman amphitheatre after it was completed.

The arch, designed by Jean-François-Thérèse Chalgrin, stands 164 feet (50 meters) tall and 148 feet (45 meters) wide. It is located in a circular plaza from which 12 grand avenues radiate, forming a star (étoile), which is why it is also known as the Arch of Triumph of the Star.

The Arc de Triomphe, in full Arc de Triomphe de l'Étoile, is a massive triumphal arch in Paris, France, and one of the world's most famous commemorative monuments. It stands at the center of the Place Charles de Gaulle (formerly known as the Place de l'Étoile), the western terminus of the avenue des Champs-Élysées.

Chichen Itza is a large Mayan ruin in Mexico's Yucatán state. It is a pre-Columbian city built by the Mayans during the Terminal Classic period that has become one of the world's most popular ancient sites.

The property features many construction techniques and building features associated with central Mexico. This demonstrates knowledge sharing among the continent's ancient peoples, or at least a similar progression of thinking patterns among tribes.

The city is said to have had a very diverse population, which contributed to the variety of construction techniques and artistic styles.

The Great Sphinx has deteriorated significantly over time, and various efforts to preserve the statue have been made since ancient times—possibly beginning during the reign of Thutmose IV (1400–1390 BCE). While the body has suffered the most erosion, the face has also been damaged, and its nose is noticeably missing. According to some, the damage was caused by Napoleon's troops, who shot off the nose with a cannon. Illustrations dating before Napoleon, on the other hand, show a noseless sphinx. Another theory holds that Muhammad Saim al-Dahr, a Sufi Muslim, mutilated the statue in the 14th century to protest idolatry.

Most scholars place the Great Sphinx in the 4th dynasty and attribute ownership to Khafre. Some believe it was built by Khafre's older brother Redjedef (Djedefre) to commemorate their father, Khufu, whose pyramid at Giza is known as the Great Pyramid. According to these theorists, the Great Sphinx's face resembles Khufu more than Khafre, and this observation has led to speculation that Khufu himself built the statue.

The Great Sphinx of Giza is the most famous statue in the world and the most instantly recognizable statue linked with ancient Egypt. The sculpture of a recumbent lion with the head of an Egyptian king was carved out of limestone on the Giza plateau during the reign of King Khafre (2558-2532 BCE) during the era of the Old Kingdom of Egypt (c. 2613-2181 BCE), although a few scholars (notably Dobrev in 2004 CE) insinuate it was invented by Djedefre (2566-2558 BCE), Khafre's brother, who attempted to steal the throne after the death of the Great Pyramid's architect, King Khufu (2589-2566 BCE).

The 138 steps, also known as the "Scalinata della Trinità dei Monti," was initially designed to connect the Spanish embassy to the Holy See at the bottom to the Trinità dei Monti church at the summit. Europe's biggest staircase was completed between 1723 and 1725 thanks to the patronage of French diplomat Etienne Gueffier, and was designed in Baroque style by Italian architects Francesco de Sanctis and Alessandro Specchi. The fresh water fountain at the bottom of the steps, Fontana della Barcaccia (which translates to "fountain of the ugly boat" due to its half-sunken ship shape), was commissioned by Pope Urban III and built by father and son Bernini.

Restoration and maintenance are frequently scheduled throughout the year, as is the case with many Roman sites. The fountain at the foot of the Spanish Steps reopened in September after being covered for most of 2014 for a facelift. The church at the top of the staircase, on the other hand, is almost entirely obscured by scaffolding until at least the beginning of 2016. However, this should not deter you from spending a few hours of your Roman Holiday in this lavish area, which is adored by so many.

The remains of Nasiruddin Mahmud, the eldest son of Shams-ud-din Iltutmish, are housed in the oldest Islamic mausoleum in India, Sultan Ghari (1167-1236). Vasant Kunj is largely unaware of it. Sultan Ghari was built between 1231 and 1232, and Qutbuddin Aibak's tomb in Lahore is the subcontinent's oldest royal mausoleum.

The tomb is located on a raised plinth within the southern ridge forest and is surrounded by a miniature fortress made of golden brown Delhi quartzite with marble highlights. It is an imposing structure with massive walls and bastions that has a distinctly military appearance.

The Washington Monument, designed by Robert Mills and subsequently finished by Thomas Casey and the United States Army Corps of Engineers, celebrates and memorializes George Washington in the heart of the nation's capital. The structure was built in two phases, one private (1848-1854) and one public (1876-1884). The Washington Monument, designed in the shape of an Egyptian obelisk to evoke the timelessness of ancient civilizations, embodies the nation's awe, respect, and gratitude for its most important Founding Father. At 555 feet, 5-1/8 inches, the Washington Monument was the tallest building in the world when it was finished.

In 1901, an electric elevator replaced the original steam-driven elevator, which took 10-12 minutes to reach the top of the monument. The Washington Monument was turned over to the National Park Service in 1933, and the first restoration of the structure began in 1934 as a Depression-era public works project. Additional restoration work was done in 1964, 1998-2001, 2011-2014 (to repair earthquake damage), and 2016-2019 (for elevator modernization).
