The Eiffel Tower is a wrought-iron lattice tower on the Champ de Mars in Paris, France. It is named after the engineer Gustave Eiffel, whose company designed and built the tower from 1887 to 1889.

The Eiffel Tower is a landmark in Paris. It was built between 1887 and 1889 for the Exposition Universelle (World Fair). It was supposed to be a temporary installation for the 1889 World Fair, held at Paris to commemorate 100 years of the French Revolution. In 1909, there were discussions regarding the potential dismantling of the Eiffel Tower. However, the decision to preserve this iconic structure was ultimately reached by city officials, who acknowledged its significance as a radiotelegraphy station.

The Colosseum is an elliptical amphitheatre in the centre of the city of Rome, Italy, just east of the Roman Forum. It is the largest ancient amphitheatre ever built, and is still the largest standing amphitheatre in the world, despite its age. Construction began under the emperor Vespasian and was completed in AD 80 under his successor and heir, Titus Further modifications were made during the reign of Domitian. The three emperors who were patrons of the work are known as the Flavian dynasty, and the amphitheatre was named the Flavian Amphitheatre by later classicists and archaeologists for its association with their family name (Flavius).

The Statue of Liberty is a colossal neoclassical sculpture on Liberty Island in New York Harbor in New York City, in the United States. The copper statue, a gift from the people of France, was designed by French sculptor Frédéric Auguste Bartholdi and its metal framework was built by Gustave Eiffel. The statue was dedicated on October 28, 1886.

The statue is a figure of Libertas, the Roman goddess of liberty. She holds a torch above her head with her right hand, and in her left hand carries a tabula ansata inscribed JULY IV MDCCLXXVI (July 4, 1776, in Roman numerals), the date of the U.S. Declaration of Independence. A broken chain and shackle lie at her feet as she walks forward, commemorating the national abolition of slavery following the American Civil War.[8] After its dedication the statue became an icon of freedom and of the United States, being subsequently seen as a symbol of welcome to immigrants arriving by sea.
