Despite the complexity of the historical inquiry into the founding of the first seven Cuban villages, Sancti Spíritus is one of the few that can accurately legitimize a date for the first years of its history.

This certainty is born from what was expressed by Fray Bartolomé de Las Casas who, in his Historia general de las Indias, written in the third person, said: …“and because Diego Velázquez departed from the port of Jagua where he had already founded Trinidad to establish a town he called Sancti Spíritus (…) such Bartolomé de las Casas, on the occasion of the Pentecost celebration, agreed to leave his house and go to say Mass and to preach to them”.
