Born in the region of Catalonia, Antoni Gaudí spent a big part of his career working in Barcelona as an architect on some of the most famous projects. Not only are some of his buildings included in the UNESCO World Heritage Site list, but his most famous one, La Sagrada Familia, an unfinished cathedral, is the largest in Europe.

One of the rare female architects to win significant commissions is Jeanne Gang. The Aqua, an 82-story residential skyscraper, one of the tallest buildings to have ever been designed by a woman, was created by Gang. The building includes some not-so-ordinary facades that are common in contemporary architecture.

Mimar Sinan was the Ottoman version of Michelangelo and designed some beautiful buildings in the Empire. Sinan designed around 300 buildings, but they are minuscule compared to the Selimiye and Süleymaniye mosques. The mosques were symbols of the Ottoman Empire's strength and represented how brilliant Sinan was.

Wright revolutionized 20th-century architecture, and his background in the Midwest helped him form his unique style. Due to the prevalent Victorian aesthetic, Wright developed the Prairie house design. Fallingwater, his most well-known structure, has stacked rectangular balconies that appear to float over the house's natural waterfall. 

Let’s jump back to older times and the figure known more for his art — Michelangelo Buonarroti. While he is already famous for his sculptures like David, he is also the mind behind the dome of St. Peter's Basilica in Vatican City. The dome, an iconic part of the building, is full of Renaissance and Gothic details and inspired other structures, like the dome on the Capitol.

Nothing is as iconic as the Flatiron building in New York, but very few know who designed it. Daniel Burnham, an American architect and one of the minds behind the Flatiron, is also known as one of the first people to contribute to the design of the first skyscraper, the Montauk Building.

Chinese American architect Ieoh Ming Pei is renowned for his distinctive glass and steel structures. He was active in the 20th century. His most well-known works include the Louvre Museum Pyramid in Paris, which uses a lot of triangles in the final design. These days, the glass pyramid is seen as a masterpiece.

Buckminster Fuller is one of the few architects to have gotten a patent for the ways he designed buildings. His geodesic dome designs, which he came up with accidentally, played an important part in the Montreal Biosphere building. Built for EXPO 67, the Biosphere was designed with sustainability in mind.

Frank Gehry, a Canadian American architect, is known for his Guggenheim Museum, which is famous for positively impacting the local economy. The museum brought in so much money that the local economy of Bilbao, Spain, which had high levels of poverty and unemployment, became one of the leading economic centers of the region.

Eleven floors up, with windows around, 520 West 28th Street, known otherwise as the Zaha Hadid Building, is the only residential building that Zaha Hadid designed. Winner of the Pritzker Prize, Hadid is known for her expressionistic style, which is visible in this building. While she did design more buildings, the New York one has become the most famous one.

Building in a sandy landscape with stone is an activity enjoyed by everyone in the world, but Imhotep took it a step further and built some of the oldest structures in the world. Imhotep, an Egyptian architect and the chancellor of Djoser, supposedly built the Step Pyramid at Saqqara, the first known structure to use stone as support.

Sir Christopher Wren, an astronomy professor at Oxford, was also an architect. A student of the baroque styles of Italy and France, Wren was commissioned to design the Sheldonian Theatre at Oxford. While the theater got destroyed during the Oxford fires, this didn’t stop him from exploring the world of architecture.

From chairs to airport centers, Eero Saarinen designed some iconic things during his career. The Tulip chair? Saarinen designed it. He was the master of futurist and modernist architecture, and it's seen in the TWA Flight Center at JFK airport. Slick and simple, the building is a welcoming sight for any tourist.

William Pereira went from designing Hollywood sets to creating some of the greatest buildings in the futuristic style he is known for. Some buildings that capture this style in the best possible way are the Geisel Library and the UCI Libraries Gateway Study Center. Both look like they were ripped from the future and placed in the modern day.

From the circular Apple Park to the tall Gherkin — Sir Norman Foster designed them with style and beauty in mind. The Gherkin might be the more memorable of the two since it perfectly captures neo-futurism with the use of windows and slick, eye-catching designs all over the building.

Not every day do architects get to design something in the Big Apple of New York. So Santiago Calatrava, a Spanish architect, had to be happy to design an addition to the World Trade Center. The Transit Hub of WTC, known less commonly as PATH station, is one of the more famous buildings that Calatvara designed.

Sir David Adjaye, during his earlier years, was surrounded by many different architectural styles due to traveling with his diplomat father.

Modernist architectural design wouldn’t be so well established and famous without the work of Oscar Niemeyer, a Brazilian architect. His most famous work, Catedral Metropolitana De Brasília, stands in the capital city of Brazil. Not only did he create the design for the building, but he helped design the whole capital city.

One of the key figures of the Chicago School of Architecture was Louis Sullivan. The Transportation Building designed by Sullivan and his colleagues is the best example of his masterful design. While it might seem simple in its design, the amount of detail present is jaw-dropping.

Deconstructivism is an architectural style whose main point is to break the traditional rules of design to produce more unique buildings. The BMW Welt and the European Central Bank building were designed by the mind of Wolf D. Prix. The BMW Welt especially captures the style of deconstructivism in the best possible way.

Renzo Piano, an architect from Italy, is not well known for having a distinctive aesthetic. As opposed to this, his structures have been varied, ranging from neo-brutalism to the beautiful, airy. His tallest structure to date is The Shard in London, a 95-story glass and steel skyscraper with a dramatically tapering shape. 

Mies van der Rohe, a German architect, reduced the building to its most basic geometric shapes, paving the path for minimalism. His designs stressed efficiency and logic as the path to beauty. The Barcelona Pavilion is an example of this architectural philosophy and has become quite important for modern architecture.

An architect is both a designer and a theorist at the same time. Rem Koolhaas was given a hard task — to design a building in a seismic zone in China.

Chinese Central Television HQ, more commonly known as "Big Pants" by the locals, has 54 stories overall and is the most famous building designed by Koolhaas.

Sometimes, war can influence the mind of an architect, like the one of Arata Isozaki. Seeing the destruction that came into Japan, Isozaki studied architecture and went on to have quite a career. A fan of the Metabolist movement in his earlier career, Isozaki went on to design some incredible pieces, like the Shanghai Symphony Hall.

If we want to feel like we live in the future, architects must push us towards it, and Richard Rogers is one of the famous ones for doing just that. Known for his high-tech and constructivist designs, Rogers garnered fame thanks to the Pompidou Center in France. The building captured the styles of the future and postmodernism.

Architecture is art too, and Philip Johnson proves this with the buildings he designed. One of the most famous representatives of modern architecture, Johnson used this style to create the famous Glass House. It removes the line between inside and outside by placing windows everywhere.
