Era Nueva

Eras (threshing floors) are spaces that were used until relatively recently to separate the grain from the rest of the dried cereal or legume plant. In this region, the threshing process was called the parva. The oldest threshing floors are often found next to farmhouses. They are circular in shape and paved with pebbles, stones or pieces of slate. Some even make use of natural sections of rock.

The traditional trillo, or threshing board, comprised a set of planks fitted with slicing blades at the bottom, originally made out of flint but subsequently replaced by strips of saw-toothed metal and later by saw-toothed wheels. The person driving the mule would ride on the trillo, which resembled a sled. Threshing floors were located in relatively high and open areas, as the threshing was followed by the aventao, or winnowing, in which the air separated the grain from the chaff. Nowadays, this threshing floor is used as a viewpoint.
