The 37th Infantry Presidential Guard Battalion, composed of five companies, a historical company and one artillery battery plus a military band, a fanfare trumpet section and Corps of Drums, is the President of Colombia's honour guard service regiment under the National Army of Colombia. It is stationed at the Casa de Nariño in Bogota where the changing of the guard ceremony takes place three days per week and carries the traditions of Simon Bolivar's infantry guards company raised in the midst of the Spanish American wars of independence in 1815.
