Probably everyone has seen Red Square and the Kremlin, probably they are the main symbol of Russia if to say in representation terms or associations. Not everyone has seen those in big detail. The star above is one of the Red Stars that are on top of the Kremlin towers. Each Red Star of the Kremlin weighs more than a ton but can rotate as weathercock
wherever the wind blows. They are made from special "Ruby Glass" and have two layers of the glass making the stars looking red in any weather. The power consumption of each star is around 5 kWt. They have been damaged during the World War 2 and were refurbished later. Below there are some more close-ups of the Red Square ensemble.
