History

The name of Caso seems to have its origins in Casios or Cayos, which were names of noble roman families that inhabited Asturias centuries ago.

The remains of a metallic axe found in Campo de Caso, capital of the municipality, seem to confirm the existence of human tribes from the Neolithic era.

There is also enough evidence that proves the Roman colonization of this area, such as the Roam road that started in Villaviciosa, crossed Caso and then finished in León.

This road linking Asturias with the Meseta (name given to the region of León) was called Camín Real, and its design is in part similar to that of the main road. It was used in the Middle Ages by the monks, emissaries, administrators and tax collectors of the time, who took the tithe and ecclesiastic rent to the Monastery of Sahagún, in León.

The Pope John the second gave this road the title of Carta-Puebla in 1447.

There was once a hospital in Caso called San Lázaro de Moño, which was opened until the 18th century, and in this hospital they cured patients suffering from leprosy, which was a very common illness at the time in Asturias.
