Córdoba Department in the context of "Cordillera Occidental (Colombia)"

Antioquia (Spanish pronunciation: [anˈtjokja] ) is one of the 32 departments of Colombia, located in the central northwestern part of Colombia with a narrow section that borders the Caribbean Sea. Most of its territory is mountainous with some valleys, much of which is part of the Andes mountain range. Antioquia has been part of many territorial divisions of former countries created within the present-day territory of Colombia. Before the adoption of the Colombian Constitution of 1886, Antioquia State had a sovereign government.

The department covers an area of 63,612 km (24,561 sq mi), and has a population of 6,994,792 (2023). Antioquia borders the Córdoba Department and the Caribbean Sea to the north; Chocó to the west; the departments of Bolívar, Santander, and Boyaca to the east; and the departments of Caldas and Risaralda to the south.

The Caribbean region of Colombia or Colombian Caribbean is the northern, coastal region of Colombia located contiguous to the Caribbean. It is mainly composed of 8 departments. It is the second most populated region in the country after the Andean Region with approximately 11 million residents according to the Colombian Census 2018. The area covers a total land area of 110,000 km (42,000 sq mi), including the Archipelago of San Andrés, Providencia and Santa Catalina in the Caribbean Sea.

The Caribbean region coast extends from the Gulf of Urabá to the Gulf of Venezuela. Straddling the coast are Colombia's two main Atlantic port cities of Barranquilla and Cartagena. The administration of the region is covered by eight department governments: Atlántico, Bolívar, Cesar, Sucre, Córdoba, Magdalena, La Guajira and San Andrés and Providencia. These eight departments also cover approximately 182 municipalities according to the 2018 Census by DANE Colombia. Most of its inhabitants speak a dialect of Caribbean Spanish with variations within its subregions.

Sinú River (Spanish: Río Sinú), is a river in northwestern Colombia that flows mostly through the Córdoba Department and into the Caribbean. It is the third most important river in the Caribbean Region, after the Magdalena River and the Cauca River. It is born in the Antioquia Department, flowing south to north for 415 kilometres (258 mi) until flowing into the Caribbean Sea. The river is navigable for only half of its length, 200 kilometres (120 mi) starting in Montería, the largest city in its basin. Also, this river is the main tourist attraction of Montería decorated with the first avenue when it passes by Montería.

The river flows between the eastern and middle prongs of the Cordillera Occidental.

Bolívar (Spanish pronunciation: [boˈliβaɾ]) is a department of Colombia. It was named after one of the original nine states of the United States of Colombia. It is located to the north of the country, extending roughly north–south from the Caribbean coast at Cartagena near the mouth of the Magdalena River, then south along the river to a border with Antioquia Department. The departments of Sucre and Córdoba are located to the west, and Atlántico Department to the north and east (most of the border formed by the Canal del Dique). Across the Magdalena River to the east is Magdalena Department. The flag of the department bears a resemblance to the flag of Lithuania.

Its capital is Cartagena de Indias. Other important cities include Magangué, El Carmen de Bolívar and Turbaco.
