15 km from Lujan City, Carlos Keen es a town that remains frozen in time, which highlights homes that preserve its traditional facade, a chapel style neo-romantic, a former postal courier, a railway station lost in the past, and granparents sit in the evenings at the door of the houses to get some fresh air, "mate" and biscuits together. The town was founded on 12 August 1881, a result of the branch railroad station Lujan-Parchment. Like many, had its heyday back in 1930 coming to have more than 3000 people. Era that ended when closing the Railroad in 1970.
