The Ducal Square was the Castle’s parade ground. For centuries, it was the town’s main square, near the palace, and home to the Town Hall. It used as a venue for festivals, “corral de comedias” (open-air comedy theatre) and, above all, bullfights. Nowadays, scenes from the Passion of Christ take place here on Good Friday, in what is locally known as the “Mandato”.
The rectangular square is accessed through an arched gateway. The houses around the square are three or four storeys high. One side of the square is taken by the Old Chapter House or Town Hall. The construction of this massive, austere building was completed in 1713. Alonso Moreno was the architect of this and all other buildings in this square.
Only the façade and first bay have been preserved. From the 14th to the late 18th century, the history of the town is linked to the Duchy of Arcos. It could be argued that the monumentality of individual buildings is due to the generous patronage of these Lords.
During the Ducal period, Marchena became a small, politically influential court. Most foundations had a religious disposition (except for the palace). This was the result of the mentality at that time.
