Its capital is 90 kilometers from the city of Medellin, the capital of Antioquia department. The municipality has an area of 149 km².

As is the case with much of eastern Antioquia, what is today Alejandria was originally inhabited by the Tahamí people.

Alejandria was founded by Don Alejandro Osorio, Mrs. Procesa Delgado, Don Salvador Cordoba and Mr. Climaco Jaramillo in 1886. By 1889 were erected the village to the township of the municipality category of Guatapé by agreement of February 20 that year.

Unlike what happened with almost all the municipalities of Antioquia, which were created by orders from departmental entities, the creation of Alejandria as a municipality was initiated by presidential decree from Bogotá. President Reyes agreed to the requests, and by decree 304 of March 1907, created the town of Alejandria.
