Спасская башня
Soldiers of the Ceremonial Unit of the Cuban Revolutionary Armed Forces guard the Mausoleum of José Marti in Santiago de Cuba. The guard is changed every half-hour, and is signaled by clock tower bells similar to how Soviet guards at the Lenin mausoleum used the bells of the Spasskaya Tower Clock. Patriotic music is played while the next batch of guards march to relive the previous guards. The music is usually played from speakers around the mausoleum instead of a live band.
