Already in the Christian period, we find in the documentation that refers to Calatorao a high number of Mudejar population in the town. Specifically, in 1350, the Mudejar population was twice as large as the Christian population: 100 Moors and 45 Christians. As a result, the 14th-15th century Mudejar aljama mosque is still preserved today. This building was located by Professor Bernabé Cabañero Subiza in 2002 in the building formerly known as the Hospital de los Peregrinos.

Other interesting elements that can be found on a stroll through the town are the parish church of San Bartolomé, a neoclassical construction from the 18th century, the group of Aragonese palatial houses from the 16th, 17th and 18th centuries or the Casino building built in 1910 and still in use.

The remains of the castle of Ariza stand on a mountain ridge overlooking the town. They have a triangular ground plan, at the foot of which the town grew, forming the current urban centre. Its situation from the defensive point of view is unbeatable, which is why it was later used in different conflicts.

Walking through Ariza we can locate the old quarters that divided the town in the Middle Ages: the Jewish quarter and the Moorish quarter, located inside and outside the limits of the wall, of which we still have vestiges today, such as the Arco de la Villa or Arco de Castilla.

The church of St. Mary, the main monument of the town, is a perfect example of the building typology of hallenkircheor hall plant, widely used in our territory during the 16th century.

Other outstanding monuments include the old hospital, the old church of San Pedro, already documented since the 13th century, the Palacio del Marqués, a building owned by the municipality that is still in use today, and the convent of San Francisco, located on the edge of the town, a Baroque construction from the 18th century.

Another interesting element is the cellar quarter, which today has about 80 cellars still standing, although it once had more than 150. Due to the large number of them in Ariza, the “cuberos” or craftsmen who made the vats and vats in the winery itself and who were used as containers to store the wine became indispensable.

The passage of different settlers is reflected in the urban fabric of the town, which has managed to combine past and present in harmony.

Of special interest is the urban complex currently known as the “Barrio Morisco”, located in the heart of Gelsa. It is a complex of a considerable extension of streets, alleys, alleys with houses of traditional Aragonese architecture and other elements of interest that take us back to the architecture of the medieval period.

Its parish church, dedicated to San Pedro Apóstol, is a 17th century construction in brick, adobe and ashlar stone plinth. It was profoundly transformed in the 19th century, giving it the appearance we see today. Inside the church is the relic of the Holy Thorn, highly venerated among the Gelsans, since, according to tradition, it comes from the crown of thorns of Jesus of Nazareth.

Other religious buildings include the Ermita del Buen Suceso (Chapel of the Good Succession), also located in the town. It is an 18th century building.
