The Kremlin and Red Square are the best known attractions of Moscow.
(They are located just close to each other, but they’re separate places.)
The Moscow Kremlin is a fortified complex; with palaces, cathedrals, walls and towers.
It’s an official residence of the president of Russian.
Red Square is the most famous city square in Russia (or maybe even in the world?).
What’s interesting, its name doesn’t come from the red color. The original Russian name of the Square can be translated as “beautiful” or “red”; the Square is beautiful so that’s the real meaning of its name. 🙂
