1. The Louvre Is the Largest Museum in the World
Of all the museums in the world, the Louvre in Paris is the largest by gallery space, covering more than 780,000 square feet, while the full complex is 2.3 million square feet. The museum was once a medieval fortress and the home to French kings before being converted into a vast Parisian Museum. It was opened to the public during the French Revolution in 1793 with just 537 paintings, many of which had been confiscated from the royal family and church during the Revolution.
In the 1980s, President François Mitterrand launched the “Grand Louvre” renovation project and commissioned Chinese-American architect I.M. Pei to design a new central entrance. Unveiled in 1989, the striking modern Glass Pyramid stirred significant public debate before becoming an internationally recognized architectural landmark.
The Louvre is home to some of the most important art and artifacts in the history of human civilization, including Leonardo da Vinci’s Mona Lisa, The Winged Victory of Samothrace, Théodore Géricault’s Raft of the Medusa, and Eugène Delacroix’s iconic masterpiece Liberty Leading the People. Because of its incredible scale, you could literally spend days wandering through the Louvre, which is why so many people come back again and again to take in more.

The Smithsonian Institution is the largest complex of museums in the world, with 21 different galleries and museums spread across the United States, including the Smithsonian American Art Museum, the National Museum of Natural History, the National Museum of African Art, and the National Air and Space Museum. Together they hold more than 155 million items and specimens, less than 1% of which are on display.
The Smithsonian also runs a large zoological park, containing a long A to Z of animals from the tiniest insects to the largest mammals. And, alongside these sites, there are eight different research stations where diverse fields are explored, including marine biology, astrophysics, environmental research, and American art.
The collections include many icons of American history, including the Star-Spangled Banner (the actual flag that inspired the national flag), the Apollo 11 Command Module, Dorothy’s ruby slipper from The Wizard of Oz, and the legendary Hope Diamond.

3. Russia’s State Hermitage Museum Has the Largest Collection of Paintings
While other museums have achieved record-breaking scale and floor space, the State Hermitage Museum in Russia currently houses the largest collection of any single museum in the entire world. They own more than three million artifacts that date from the Stone Age to the early 20th century.
Once the home of Russian Tsars, this impressive stretch of six buildings running along the river Neva was converted into a court museum in 1764 by Catherine the Great to house her impressive collection of paintings. One of the museum’s star attractions is its Gold Rooms, showcasing priceless gold masterpieces from Eurasia, the Orient, and the Black Sea Littoral. They also own masterpieces by Western artists, including Rubens, Titian, Goya, Picasso, and Van Gogh. It is estimated that if you looked at everything for just one minute, it would take 11 years to see the full collection.
Since the 18th century, the museum has maintained an official resident population of around 50 to 70 cats to guard the vaults and galleries against rodents. Empress Elizabeth ordered the first cats from Kazan in 1745, and today they even have their own press secretary, medical staff, and annual celebration day.

Established in 1872, it combines an expansive architectural complex with a collection of extraordinary cultural significance.

10. British Museum Holds Eight Million Objects of Global Cultural Heritage
The British Museum in London is the world’s first national public museum, established in 1753 and opened to the public in 1759. Dedicated to human history, art, and culture, it chronicles the story of human civilization from its earliest beginnings to the modern day. Initially holding just 71,000 objects, it expanded quickly, so much so that collections had to break away to form independent institutions, including the Natural History Museum (1881) and the British Library (1973). Today it has over eight million objects and almost one million square feet of display space.
Collection highlights include the Rosetta Stone, a stele carved with Hieroglyphic, Demotic, and Ancient Greek text, unlocking the translation of Egyptian Hieroglyphics. There are also the controversial Elgin Marbles, taken from the Parthenon in Athens. There is the treasure of the Sutton Hoo ship burial.
The museum also holds extensive collections covering Egypt and the Sudan; Greece and Rome; the Middle East; Britain and Europe; Asia; Africa, Oceania, and the Americas; Prints and Drawings; and Coins and Medals. Only about 1% of the collection is on public display.
