[2] The Laraos District is one of oldest of the Yauyos Province, and its history is ample and emerges from the pre-incan times.

Its preceding town is Sinchimarka, cradle of forgers, but simultaneously brave and militant men, like all the tribes who conformed the Yauyos, who were tenacious resistants before being conquered by the incan leader Pachakutiq.

Thus this one acquires the denomination of Santo Domingo de Cocha Laraos, being one of the most important towns and then they contributed in the process of cristanization of the inhabitants of Yauyos.

With the Andean transculturization it is transformed into Laraus (plural), so it means paved streets, and with the castellanization it is pronounced Laraos.

The town is divided into ten main streets: Callhuapampa, Ansaya, Larpa, Callampa, Súniqui, Cancayllu, Achallanca, Warcaña, Caracara and Chunchillo.
