The Church of Santos Juanes or Sant Joan del Mercat is a Catholic church located in the Mercat neighborhood of the city of Valencia, Spain. By the mid-13th century, a church was built atop the site of a former mosque, initially in a Gothic style; however, fires in the 14th century necessitated reconstruction. A major fire in 1592 led to another reconstruction, commissioned by the Archbishop and Viceroy Juan de Ribera in an exuberant Baroque style completed in 1700. This was located in the Boatella neighborhood, then working class quarters, outside the town walls, that housed some of the Morisco population.
The main facade of the church retains a walled-up oculus of a rose window from the older church. The square exterior of the apse, facing the piazza, houses a central niche decorated with a stucco statuary group of the Virgen del Rosario (Virgin of the Rosary) attributed to Jacopo Bertesi. The group display the Virgin and Child (his hand on the globe) ensconced in a burst of rays, angels, and cherubs. Other portals contain the symbols of John the Baptist (lamb) and John the Evangelist (eagle). The center is surmounted by a clock tower, and a roofline dominated by statues of the Juanes: including the Baptist, the Evangelist, and Saints Francesco Borgia and Luis Bertrán. This facade includes profuse complex iconography including a lamb atop a book with five seals.
The interior has statues depicting the 12 tribes of Israel, also by Bertesi, and large ceiling frescoes depicting numerous themes of the Church Triumphant by Antonio Palomino. The church interiors, including the frescoes, suffered arson damage during the Spanish Civil War.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
