Crossing the Roman “Borsao” by the Carrera arch, we access Borja, a city with traces of three cultures: Sephardic, Islamic and Christian. The collegiate church is the result of overlapping styles, the result of different reforms and extensions. Next to this building is the museum in what was once one of the city hospitals: that of Sancti Spiritus and, right opposite, la casa de las Conchas. Built in the 16th century it can be considered the most important in the city. Its name comes from the frameworks in the shape of a shell placed on the façade. The Convento de la Concepción is the most beautiful expression of baroque in the city, which is demonstrated in the cloister and the church decorated with beautiful frescoes.
Two interesting buildings stand out in the Plaza del Mercado: the Angulo Palace, with a spectacular entrance and the so-called “Torreón de los Borja”. The town hall is one of the characteristic buildings of Aragon architecture of the 16th century. Among its streets we can admire many noble houses with modest façades with carved eaves, galleries, and façades under semi-circular arches. All of these features date back to the 16th to 19th centuries.
