Located in the lowest part of the village, it owes its name to the old Arenas market, built in the middle of the last century. It had the shape of a pigeon house and was located in the traditional market area.
A little further down, in the Pozo de los Corredores, the village farmers used to meet to sell their produce to the dealers who came from other towns to buy, as if it were an open-air market. Nowadays, this well is located inside a house, next to the old entrance arch of the village.
