One of the most beautiful towers on the perimeter is the Spasskaja Bašnja or Savior Tower, where the tsars once entered the Kremlin. It was designed by the Italian architect Pietro Antonio Solari at the end of the 15th century, but it was modified in the 17th century when a carillon of 10 bells was added, taking up three floors of the building and weighing 25 tons!
Fun fact: did you know that the carillon of the Savior Tower chimes four times a day? At 6 a.m. and 12 p.m., you can listen to the Russian National Anthem, and at 3 p.m. and 7 p.m., it plays a melody called “Gloria” by the composer, Michail Ivanovič Glinka.
