[6] Matanzas was the site of several slave insurrections and plots, including the infamous Escalera conspiracy(es) (discovered in late 1843, see also Year of the Lash).
Due to the high number of both slaves and, importantly, free Afro-Cubans in Matanzas, the retention of African traditions is especially strong there.
The name Matanzas means "massacre" and refers to a putative slaughter in 1510 at the port of the same name, in which 30 Spanish soldiers tried to cross one of the rivers to attack an aboriginal camp on the far shore.
However, once they reached the middle of the river, the fishermen flipped the boats, and due to the Spanish soldiers' heavy metal armor, most of them drowned.
According to municipal historian Arnaldo Jimenez de la Cal, "[i]t was the first act of rebellion of natives in Cuba."
To the south-east, the landscape rises into a hill called Pan de Matanzas, divided from the Atlantic coast by the Yumuri Valley and a coastal ridge.
[8] In 1952 it acquired tramcars from Havana Electric Railway, but converted with buses by new owners Omnibus Urbanos SA in 1954.
The Aqueduct of Matanzas, today a national monument, was built in 1870 and is still providing the city with water from the spring Manantial de Bello.
