The oldest part of Sevilla lies on the left bank of the Guadalquivir River and is irregularly planned, with a maze of narrow and twisting streets, small enclosed squares, and houses built and decorated in the Moorish style. There is a somewhat more spacious layout in the central district near the Cathedral of Santa Maria and the Alcázar Palace. Sevilla’s cathedral is one of the largest in area of all Gothic churches. Most of it was constructed from 1402 to 1506 on the site of the city’s principal mosque, which had been built by the Almohads in 1180–1200 on the site of an earlier Visigothic church. One of the mosque’s few surviving portions, its minaret, called the Giralda, was incorporated into the cathedral as its bell tower. The minaret has surfaces almost entirely covered with beautiful yellow brick and stone paneling of Moorish design. The main portion of the Cathedral of Santa Maria is built in the Late Gothic style of France, but its various parts display building styles ranging from the Moorish through the Gothic to the Plateresque and the Baroque. The cathedral’s interior contains paintings by Murillo and Zurbarán, among others.

The finest survival from the Moorish period is the Alcázar Palace, which lies near the cathedral. The Alcázar was begun in 1181 under the Almohads but was continued under the Christians; like the cathedral, it exhibits both Moorish and Gothic stylistic features. A decagonal brick tower, the Torre del Oro, once part of the Alcázar’s outer fortifications, remains a striking feature of the riverbank. Other examples of Moorish building are the tower of the Church of San Marcos (once the minaret of a mosque) and two sides of the cathedral’s Patio de Naranjos. Sevilla has many other churches built in the Gothic, Renaissance, Baroque, and Rococo styles.
