Red Square, by any chance?
Red Square in Moscow got its name from the Russian word "krasnaya," which means both "red" and "beautiful." Originally, the square was called "Pokrovskaya Ploshchad" due to the nearby Church of Intercession, but over time, its association with the color red and its significance as a picturesque and central location led to the adoption of the name Red Square. The square has since become a symbol of Russian history and culture.
