Squatting in Venezuela is the occupation of derelict buildings or unused land without the permission of the owner. Informal settlements, known first as "ranchos" and then "barrios", are common. In the capital Caracas notable squats have included the 23 de Enero housing estate, Centro Financiero Confinanzas (a derelict skyscraper) and El Helicoide, a former shopping centre which is now a notorious prison.
