Starting from the Square, I can still feel the imposing gazes of José Martí, Che Guevara, and Camilo Cienfuegos.

One thing you have to leave the (former and/or nominally) socialist nations is their love for great central squares, be it cities or smaller towns. A place well looked after and with historic meaning. It's simply beautiful!
Are there a lot of festive events on the Revolution Square in summer?
