When people talk about the Russian Kremlin, they usually picture that massive red wall in the middle of Moscow. You know the one. It sits right next to those colorful "onion domes" of St. Basil’s Cathedral—which, weirdly enough, isn't actually part of the Kremlin itself.
Honestly, there is a lot of confusion about what this place actually is. Is it a palace? A fortress? The Russian version of the White House?
The short answer is: yes, it’s all of those things. But the word "kremlin" basically just means "fortress inside a city." There are actually several kremlins across Russia—like the ones in Kazan or Novgorod—but the one in Moscow is the big one. It’s the heart of the country, both literally and figuratively.
What is the Russian Kremlin? (It’s bigger than you think)
Basically, it's a 68-acre fortified complex. To put that in perspective, you could fit about 50 football fields inside those walls. It’s a triangular shape, tucked between the Moskva River and Red Square.
If you walked the whole perimeter, you’d cover over 2,200 meters. The walls are thick, too—up to 6.5 meters in some spots. Back in the day, that was enough to stop almost any army. Today, those walls mostly serve to keep the world’s most powerful Russian politicians separate from the tourists taking selfies in the Alexander Garden.
Inside, it’s a weird mix of ancient cathedrals, 19th-century palaces, and blocky Soviet buildings that look a bit out of place. It’s where the President of Russia works, but it’s also a massive museum.
The stuff you can actually see
Most of the territory is actually closed off to the public. You can't just wander into the President's office. However, about a third of it is open, and that’s where the good stuff is:
- Cathedral Square: This is the spiritual center. You’ve got the Assumption Cathedral, where the Tsars were crowned, and the Archangel Cathedral, which is basically a giant tomb for Russian royalty.
- The Armory Chamber: Forget guns and shields (though they have those too). This place is where the Faberge eggs and the Crown Jewels live. It’s arguably the most expensive room in the country.
- The Tsar Cannon and Tsar Bell: These are essentially the world's biggest "fails." The cannon is huge but has never been fired. The bell is the largest in the world but it cracked during casting and never rang. Very Russian.
A quick history of the "Red" walls
Here is a fun fact: the Kremlin wasn't always red.
In the 14th century, Prince Dmitry Donskoy built the walls out of local white limestone. For a long time, Moscow was actually known as the "White-Stone City." It wasn't until the late 1400s that Ivan the Great brought in Italian architects to redo the whole thing in red brick.

Why Italians? Because at the time, they were the best in the world at building fortifications. You can still see that "Renaissance" influence in the swallow-tail battlements along the top of the walls—they look almost exactly like the castles you’d find in Northern Italy.
Those bricks have seen a lot. Napoleon tried to blow the whole place up when he retreated in 1812. He planted mines under the towers, but a lucky rainstorm put out many of the fuses. The damage was still bad, but the Kremlin survived.
The Kremlin in 2026: Politics and Power
In the modern era, "The Kremlin" has become a metonym for the Russian government, much like "The White House" or "10 Downing Street."
As of January 2026, it remains the nerve center of the Russian state. President Vladimir Putin recently outlined several strategic tasks for the year from within these walls, focusing on things like "technological sovereignty" and demographic shifts. When the news says "The Kremlin decided," they aren't talking about the buildings; they're talking about the administration working inside the Senate building (that’s the one with the yellow walls and the green dome).
It is a place of high security. If you visit today, expect to go through multiple checkpoints. You’ll see the Presidential Regiment—these guys are the elite guards in tall boots and blue uniforms—marching around.

Why the location matters
The Kremlin sits on Borovitsky Hill. It’s the highest point in the area, which made sense for a 12th-century wooden fort. Today, that elevation just adds to the "looming" feel of the place. It looks down on everything else in Moscow.
It’s also right next to Red Square. People often think the Kremlin is in Red Square, but they are separate entities. Red Square is the open plaza; the Kremlin is the walled-off city next to it.
Tips for actually visiting
If you’re planning to go, don’t just show up and expect to get in.
- Buy tickets online. The queues at the ticket office in Alexander Garden are legendary, and not in a good way. In the summer, you can wait for over an hour just to get to the window.
- The Diamond Fund is separate. This is a tiny, high-security room inside the Armory. You need a specific ticket for it, and they only let a few people in at a time. It contains the 189-carat Orlov Diamond. It's worth the extra hassle.
- No big bags. Security will make you check anything larger than a small handbag. There is a luggage room near the Kutafya Tower, but it's easier to just leave your backpack at the hotel.
- Thursday is the day off. Don't be the person who walks all the way there only to find the gates locked. The Kremlin is closed to visitors every Thursday.
Is it worth the hype?
Honestly, yeah. Even if you don't care about politics, the architecture is stunning. Where else can you see a 15th-century church right next to a 1960s glass-and-concrete concert hall (the State Kremlin Palace)?
It’s a weird, beautiful, and sometimes intimidating place that tells the whole story of Russia in one go. From the Mongol invasions to the Tsars, the Soviets, and the current administration, every layer of history is literally baked into those red bricks.
If you're going to Moscow, it's the one place you can't skip. Just remember to bring your passport—they check IDs more often than you'd think.
What to do next
If you're interested in the history, check out the official Moscow Kremlin Museums website to see which exhibitions are running. If you're more into the political side, the English-language portal of the President of Russia (kremlin.ru) actually publishes transcripts of most major speeches and decrees happening inside those walls right now. It's a fascinating, if somewhat dense, look at how the place functions today.
