In the late 1950s construction of the Barcena reservoir [es] forced the relocation of the inhabitants of two villages which were to be inundated, ancient Barcena and Posada del Rio. The result was the construction of Posada del Bierzo.
In the village fruit production predominates, particularly pears and apples. They are shipped to cooperatives and exported to various cities of Europe.
