Sincelejo (Spanish pronunciation: [sinseˈlexo]) is the capital and largest city of the Colombian department of Sucre in the Caribbean region.

The most widely accepted theory is that the Spanish city is named after the cacique, Cincel, who is believed to have been the leader of the indigenous people who inhabited the area where the town was founded.

One author states, without citation, that this theory is supported by documents in the General National Archives (AGN) in Bogota.

The geography of Sincelejo is characterized by a hilly landscape which extends from the mountains to the borders of the plateau in the north and south.

The small mountain foothills in the municipality span from the marine fluvial plain in the west to the border shared with the town of Palmito.

Erosion is common in the rugged topography of the rolling hills, which are moderately to strongly broken, with slopes between 7 and 50% and altitudes ranging from 50 to 260 meters.

Sincelejo is bordered by the municipalities of Palmito and Tolú to the west, Sampués and Córdoba Department to the south, Corozal and Morroa to the east, and Toluviejo to the north.

[11] The main economic activities of the municipality of Sincelejo revolve around the land use of neighboring departments, specifically in livestock, agriculture, and commerce.

Sincelejo also has a significant dairy farming sector, but beef cattle are the dominant contributor to the city's economy.

Industry is beginning to grow in the city with new factories, including Postobón facilities, almidón (starch production), clothing, footwear, icopor (styrofoam), metal equipment, bricks, concrete, construction materials, and wood processing.

[12] Sincelejo is best known for its annual festival called Fiestas del dulce nombre de Jesús (English: Celebrations of the Sweet Name of Jesus), which is held every year on January 20.

On January 20, 1980, a combination of overcrowding and panic caused the bullring's wooden bleachers to collapse, killing at least 222 people, although some estimates place the total number at 400.

Today, the construction of the temporary bullring starts towards the end of December, and civil engineers and architects supervise the project.

Anyone participating in the event as a bullfighter must purchase insurance, which is sold on site, to cover emergency medical care in the ring.

Saint Francis of Assisi Cathedral: The Catedral San Francisco de Asís was established in 1853 and is located adjacent to Santander Park.

It is the center of the religious celebrations and festivals in Sincelejo, including Las Fiestas del Dulce Nombre de Jesús.

15 kilometers away from Sincelejo is Las Brujas Airport where there are daily flights to the major cities of Bogotá and Medellín.
