The House of Tithing is organized in two parts articulated around two separate patios, one residential or for administration attached to the barns, and the other for storage.The storage space is distributed around a large rectangular courtyard with arcades on all four sides, these arches are supported by strong pillars. In the surrounding galleries we find the storage bays for grain. This building in Carmona (Seville, Andalusia) is completely symmetrical except for its eastern and southern sides that adapt to the shape of the plot.
