Concatedral de San Nicolás el Magno

The Concatedral de San Nicolás el Magno is a neoclassical church in Rionegro with three naves arranged in a rectangular layout, built with limestone and brick walls reinforced using mud construction methods. Its interior displays the clean geometric lines typical of the neoclassical style.

An original structure on the site dated from 1668 but was demolished in 1793 on the orders of Bishop Velarde y Bustamante. The current building was constructed in its place and completed in 1804.

The building is dedicated to Saint Nicholas and remains central to Rionegro's community life. Locals gather here for worship and celebrations, while its design reflects the religious values that have shaped the city.

Visitors can stop by throughout the week and weekends to explore the architecture and religious art collection. It is advisable to wear respectful clothing and remain quiet during Mass times.

In 1812, the Constitution of the Independent State of Antioquia was signed within these walls, marking a pivotal moment in Colombian independence. This event made the building a symbol of political transformation during the independence movement.
