Extended information:

The Tomb of the Unknown Soldier in Moscow is located in the Alexander Garden outside the red wall of the Kremlin on the northwest side of Red Square. It was built on the eve of Victory Day in the Patriotic War in 1967.

This is the "No. 1 post in the country" known to Russian women and children. It is said that this "first post" was originally located in front of Lenin's tomb, but it was unknown when it was moved here. There are 12 rectangular granite markers arranged in the west of the tomb of the martyrs, symbolizing the 12 heroic cities in the Patriotic War.

Beside it is the Monument to the Goddess of Victory. The monument is made of iron and has three edges like bayonets. Each edge is an iron relief, showing the Patriotic battles of 12 Soviet hero cities. The monument is 141.8 meters high, symbolizing the 1,418 days and nights of the Patriotic War.

The sculpture on the front of the monument is of the magical warrior Georgi stabbing a giant snake with a spear, comparing the 27 million soldiers and people who died in 1814 days and nights to Saint George who acted for heaven. The base has 5 levels of steps, each level representing a year of war. 100 meters away from the top of the monument is the Greek goddess of victory, holding a golden victory laurel in her right hand, with two chubby angels flying beside her, one male and one female, blowing the trumpet of victory.
