Corrales were theatres created from the spaces in courtyards. The courtyard was lined by several-floored, covered galleries designated for a concrete type of society. The fourth side was occupied by a covered stage. The courtyards were in the shape of a rectangle or square with their centre left without a roof, the so-called patio. The majority of the audience would stand there. Over the course of time rows for seating came about under the roof, along the patio and in front of the stage.
