One of the oldest and most photographed squares in Cordoba, it owes its name to the horse and mule trade that took place there.
A reminder of this activity is the colt that crowns the octagonal fountain dating from 1577, which was built to improve the water supply for the local residents. The colt, which holds the coat of arms of Córdoba between its legs, was added in the 17th century.
On the other side of the square stands a triumphal statue of San Rafael, the work of Michel de Verdiguier, built in 1768 and moved to this square in 1924. The square was conceived as a square enclosure, enclosed where Calle Lineros now runs.
The square was immortalised by Cervantes, as can be seen in the tiles installed in 1917 on the façade of the Hospital de la Caridad. Today, this former hospital houses the Fine Arts Museum and the Julio Romero de Torres Museum.
On the other side, the Posada del Potro, now converted into the Centro Flamenco Fosforito, tells us of the commercial past of this square.
