The Spasskaya Tower (Frolovskaya) is a travel tower of the Moscow Kremlin overlooking Red Square. It was built in 1491 by the architect Pietro Solari. In 1624-1625 (according to other sources - in 1626 [6]), the English architect Christopher Galoway built the tower with a multi-tiered top in the Gothic style. In 1937, a pommel in the form of a ruby ​​star was placed on the structure. At the top of the tower are the famous chimes.
