If you’re an architecture/engineering student or planning to become one, you’re in for a treat. That’s because today, we’ll consider the most significant works architecture this world has seen. As the main title suggests, we won’t stick to a specific time frame. Ever since our species started building objects, there were projects so marvelous that it would be a shame not to mention them. However, keep in mind that due to the structure of this article, we won’t be able to mention every single monumental work. We apologize in advance to all the builders whose work won’t be mentioned here. So without much further ado, here are some of the most significant works of architecture our world has seen until today!
Top 08 Most Significant Works Architecture
#1 La Sagrada Familia
We’ll begin by mentioning Barcelona’s most famous monument – La Sagrada Familia. If you’ve ever seen a postcard from this area of Spain, you probably know what this cathedral looks like. This object represents perhaps the most incredible work of the legendary Catalan architect Antoni Gaudí. Here’s a fun fact: it’s still under construction.

The phenomenal combo of Gothic and Art Nouveau styles makes this object a sight one should definitely see in person. At least once in their lifetime, that is. Also, if you’re wondering why’s it taking it so long for it to be completed, go visit Barcelona and its most recognizable building.
#2 Parthenon
Now let’s go back about 2500 years in history and visit ancient Greece with its best-preserved temple – Parthenon. It was built in the fifth century BC to honor the goddess Athena Parthenos. It has influenced how we see and talk about the western art world since its completion. The building hasn’t lost its appeal, as many tourists from every part of the world flock to Athens to visit this ancient monument. Art historians consider the building’s sculptures, ornaments, and friezes some of the best and finest examples of Classical Greek art. Lastly, its architect Phidias is still seen as one of the best sculptors and builders of all time.
#3 Fallingwater House
Now, let’s talk modernist architecture! Have you ever heard about an architect called Frank Lloyd Wright? You’ve probably seen his most admired work – Fallingwater House near Pittsburgh, Pennsylvania. This fantastic piece of art was built in 1935 and still represents an untoppable architectural work in the fusion between artificial/modern and natural. It’s located about 70 miles southeast of Pittsburgh and gives off this familiar vibe of living in a small town but enjoying all the benefits of modern technology.
Interestingly enough, this blend of modernity and nature perfectly describes the benefits of living in a small town in Pennsylvania. And who knows, maybe it can benefit your lifestyle as well. Lastly, let’s just say that Fallingwater House was named “the best all-time work of American architecture” in 1991 by the AIA (American Institute of Architects). However, its uniqueness goes beyond the American continent; nowadays, it’s one of the most significant works of architecture worldwide.
#4 Flatiron Building

Let’s stay on the continent for a bit longer. Here we’ll consider one of NYC’s most iconic objects – the Flatiron Building. It was built in 1902 by an architect called Daniel Burnham. It stood as the tallest building in NYC. Needless to say, that all changed pretty quickly. However, its unique design prevails. Therefore, it wasn’t forgotten. Quite the contrary! Many people would recognize it by its triangular shape in an instant!
#5 Taj Mahal
And now for some architecture of the eastern world! There isn’t a better way to start our talk about it than to mention the glorious Taj Mahal in Agra, India. One could easily say that it is one of the most breathtaking objects in the world, and not a single person would disagree. Basically, the whole building is the tomb of the Mughal emperor Shah Jahan’s late wife. In other words, the Taj Mahal is the outcome of a relationship between two people. Still, it dramatically differs from the houses of many famous Hollywood couples in terms of beauty. The building combines various influences, mainly from the regions surrounding it. Therefore, we can recognize a mixture of Persian, Indian, and Islamic architecture.
#6 Burj Khalifa
Currently, this building represents the tallest structure in the world. We’re talking about a whopping 828.9 meters of height. This so-called mammoth skyscraper is part of downtown Dubai, UAE. The construction lasted for six years (2004-2010), and for 12 years, no building has topped it. If you’re traveling near or through the United Arab Emirates, there’s no reason why you should miss out on visiting Burj Khalifa. It’s one of the major architectural achievements of the 21st century. Thanks to all the AI advancements in the construction industry, we can only imagine what will happen next.
#7 The Leaning Tower of Pisa

How could we ever think of a list of the most significant works of architecture without the most famous leaning structure in the world? You’ve seen it in hundreds of photos on your Facebook wall. Yup, those photos where your friends stand with one of the arms “placed” on the structure behind. The famous Leaning Tower of Pisa is one of the most remarkable works of European medieval architecture. Also, if you’re planning to visit this monument, don’t worry about it falling over once you’re on the top. You’ll be able to climb its 297-step spiral staircase and enjoy the beautiful skyline over Pisa.
#8 Sydney Opera House
Lastly, let’s pay a visit to the Land Down Under. The most authentic piece of architecture in Australia is, without any doubt, the iconic Sydney Opera House. It was designed by the Danish architect Jorn Utzon and completed in 1973. No need to emphasize that it is the most iconic architectural object in the last 50 years or so. Its quite elegant, sail-like structure is adored by many. We have numbers to back that up: more than seven million people visit this building annually. Also, it’s been made a UNESCO World Heritage Site.
