This sugar mill valley is in the province of Sancti Spiritus, Cuba.
The ruins of Manacas plantations, sugar mills and old colonial
estates are silent witnesses to African slaves, who were brought by force to Cuba by the Spanish conquistadors.
Iznaga Observation Tower was built in 1816.
The seven-story tower is 45 m high and crowned by a watchtower where the Iznaga family could climb to the top and see the vast sugar lands and some 15 of the valley’s 57 mills.
Three bells in the tower, each with a different sound, rang out
messages. The large bell signaled the start and end of work; the medium one, a holiday; and the small one, Easter week. The large and medium ones rung together told of a slave escape; the large and small together, a slave rebellion; and all three at once meant an invasion by pirates.
