Better known as the Church of La Trinidad, the Church of San Juan y Todos los Santos is the result of the merger of three religious institutions: the former Convent of La Trinidad and the parishes of Omnium Sanctorum and San Juan de los Caballeros. The first two were founded by Fernando III El Santo.
At the end of the 17th century, construction began on the current building to replace the previous one, given its state of ruin.
Almost nothing remains of the old Ferdinandine churches, as most of the heritage of the current church belongs to the 18th and 19th centuries. Part of the convent’s outbuildings were used as barracks, a use that still survives today.
The ground plan of this neoclassical church has a single nave with a small transept. The interior has a notable set of 18th-century altarpieces, as do the two façades, which were begun in the mid-17th century and soon became the prototype of the Baroque church.
Its main façade is notable for the presence of the Solomonic column, used for the first time in Cordoba.
The exuberant ornamentation of its altarpiece and the mural paintings by Antonio Palomino representing motifs from the Old Testament are also noteworthy.
