Introduction to the National Palace of Mexico: The National Palace of Mexico is a paradise of murals, where masterpieces of famous Mexican masters are collected. Located on the east side of Plaza de la Constitución in Mexico. The main building of the National Palace is a three-story building complex that integrates Indian, Spanish colonial and modern architectural styles. Sitting east and facing west, it is divided into three parts: south, middle and north. There is a gate in the middle of each part. There is a central balcony on the third floor. In the niche above the balcony hangs the big bell that Father Hidalgo, the father of Mexican independence, rang as the "Call for Independence." Every year at 12:00 midnight on September 15th, the President of Mexico stands on the third-floor balcony and presides over the "ringing ceremony" to celebrate Mexico's independence. Then he waves the national flag and shouts to the people gathered in Constitution Square: "Long live Hidalgo!" "Independence" "Long live Mexico!"
