Seaside tourist resort that was born in the 60s thanks to some foreign entrepreneurs (Belgians and Germans) who bought most of the building land to build houses and villas. The origin of the name is debated, it could derive both from "king" in the sense of sovereign, and from "rei" in the sense of perpetrators of crimes (since the former penal colony of Castiadas rises not far from here.

The prison was born at the end of the 19th century as an agricultural colony, the prisoners were placed in these areas to reclaim the marshes and create new roads as, due to malaria, this area had been abandoned for many years. The history of these structures is very interesting.
