Cubagua or Isla de Cubagua (Spanish pronunciation: [ˈisla ðe kuˈβaɣwa]) is the smallest and least populated of the 3 islands constituting the Venezuelan state of Nueva Esparta, after Isla Margarita and Coche. It is located 16 kilometres (10 mi) north of Araya Peninsula, the closest mainland area.
The island is 9.2 by 3.6 km (5.7 by 2.2 mi) in size, an elliptical shape with the longer axis east-west. Its area is 22.438 km2 (9 sq mi). The coast consists of some beaches as well as cliffs from 5 to 7 metres (16 to 23 ft) high in the south and from 20 to 24 metres (66 to 79 ft) high in the north. The highest elevation of the flat-topped island reaches 32 metres (105 ft).
It is dry and lacks surface water bodies (the only freshwater is found in small underground reservoirs). Annual precipitation is 250 millimetres (10 inches), which is the value of a dry desert. Temperatures are close to 25 °C (77 °F) year-round with little fluctuation.
The desert-like (xerophytic) vegetation of the essentially barren island includes a number of cactus species such as Cardón de Dato (Ritterocereus griseus), Buche, Melón de Cerro, Sabana o Monte (Melocactus caesius), Guamacho (Pereskia guamacho), and Opuntia tuna as well as a few legumes (family Fabaceae) such as Mesquite (Prosopis juliflora), Divi-divi (Caesalpinia coriaria), Poorman’s Friend (Stylosanthes viscosa), and the Sangre Drago (Croton flavens).
The island has small populations of hares, feral goats and a large population of dogs.
The island of Cubagua has no streets or roads. It is served by ferries and other boats from Punta de Piedras, the capital of the municipality of Tubores located 8 km (5 mi) to the northeast on Isla Margarita. The passage takes less than 2 hours. The boat landing pier is located at the eastern end of Playa Charagato, the main settlement of Cubagua.
A lighthouse marking Punta Charagato lies in the northeast to aid the Isla Margarita ferry and another lighthouse is situated at Punta Brasil in the northwest to aid the ferries of Punta de Piedras and Puerto la Cruz.
The first human settlement on Cubagua has been dated to 2325 BC, a time within the Meso-Indian Period (5000-1000 BC).
In 1498, Cubagua was discovered by Christopher Columbus. In 1528, Cristóbal Guerra founded the city of Nueva Cádiz, the first settlement to hold the title of "city" in Venezuela. The city became a synonym for the suppression by the Hispanic Conquistadores in South America. Nueva Cádiz, which reached a population between 1000 and 1500, was destroyed in an earthquake followed by a tsunami in 1541. The ruins have been declared a National Monument of Venezuela in 1979.
Human activity dates from the 24th century BC, but the first people did not settle here in a permanent fashion. Instead the island was used as a source of oysters, for food, and for pearls. The lack of vegetation or fresh water made permanent settlement nearly impossible. Today the island still has temporary fisherman, but few to no permanent residents.
According to an unofficial population census conducted by the Instituto del Patrimonio Cultural in August 2007, the island had 51 residents of which 19 were children. The population resides in the following 4 communities in the island's northwest:
- Playa Falucho
- Playa Charagato (the largest settlement)
- Punta Charagato
- Punta la Cabecera (close to the ruins Nueva Cádiz)
In addition, on some maps a settlement called Punta Arenas appears in the Southwest. Satellite images reveal about 5 buildings at that site. A small settlement of about 4 buildings can be made out about midway between Punta La Horca (the westernmost point of Cubagua) and Punta Arenas south of Punta El Lamparo. A pair of buildings can be seen on the southern bay of Manglecito just east of Punta Manglecito.
The population exceeds 300 during the year when seasonal fishermen from the Venezuelan mainland state of Sucre are included.
In popular Culture
In 2015, Venezuelan director Jorge Thielen Armand made a short documentary about the island of Cubagua, Flor de la Mar.
