Patio de Banderas, Royal courtyard at Alcazar complex, Seville, Spain

The Patio de Banderas is a rectangular courtyard within the Alcázar complex featuring two rows of orange trees and a central hexagonal fountain. The space is surrounded by palace buildings on all sides, creating an enclosed plaza with paved ground.

Known as Plaza Grande until Pablo de Olavide's 1771 plan recorded the name Patio de Banderas, the square lies inside the Alcázar walls. In the 1970s remains of a Christian basilica, possibly of the 4th century and used in Roman and Visigothic times, were found beneath it. In 2021 the Junta de Andalucía treated it as part of the Alcázar.

The name comes from a cluster of flags painted on the wall gate opening onto the Plaza del Triunfo; the square was labelled plaza Grande until Pablo de Olavide's 1771 plan recorded the name patio de Banderas. Inside the entrance arch stands a late-17th-century altarpiece with the Immaculate Conception flanked by Saint Joachim and Saint Anne, and Saints Peter and Ferdinand at the sides.

The courtyard is a public square entered from Plaza del Triunfo through an arch and also from Calle Judería via a passage. From here you reach the Apeadero del Alcázar. The ground is packed earth (albero) in the centre with cobbled pavements along the sides.

The name comes from a cluster of flags painted on the wall gate that opens onto the patio from the Plaza del Triunfo. The entrance arch shelters a late-17th-century altarpiece of the Immaculate Conception flanked by Saints Joachim and Anne, with Saints Peter and Ferdinand at the sides and Saint Joseph with the Christ Child above.
