586  kilometers  from Buenos Aires City and 264 kilometers above sea level, in the south of Córdoba province, on the Laboulaye-Sampacho railway, Adelia María was built in the old Ambrosio Olmos’ Santa Catalina Ranch.

Adelia Marķa, a real positive young town, was born by the initiative of the Buenos Aires Railway, administrated by Franklin and Herrera Company, in 1928. Our town does not have neither a  foundation document nor a historic person to remember but it should be proud of having developed as a  consequence of progress.

The Railway Company, interested in these agricultural colonies, decided to build a new railway, that is why, Mrs. Adelia Marķa Harilaos de Olmos donated the lands. The title deed  was inscribed  in Córdoba on 12^th July, 1928.

By Government decision, the company had to divide the land into plots for the town development which should include  a park, a school and a police station.

Most  immigrants established  to  the south of the Railway Station, and  many others, to the north.
