Kremlin Chimes on Spasskaya Tower, Moscow
Usually referred to as the Kremlin Chimes because of its distinctive-sounding bells, this clock sits on a tower that was constructed in the late 1400s. It was added to the 10-story red-brick structure in the 17th century and was updated about 200 years later. The whole of Spasskaya, with the unmistakable architecture of the Kremlin behind it, can be seen from the famous Red Square. The tower's spire is topped by a five-pointed star that is always illuminated and that moves with the wind like a weather vane.
