Torre Blanca, Islamic tower in Seville, Spain.

Torre Blanca is an Almohad fortified tower on Seville's Ronda Histórica, built between the 12th and 13th centuries. It has an irregular octagonal plan and is made of mortar and brick. Inside, it had two vaulted floors with living quarters. It is the only tower in the walled complex that keeps its stretch of wall, along which eight smaller, simpler towers stand.

The Torre Blanca was built between the 12th and 13th centuries as part of the Almohad wall linking the Macarena and Córdoba gates, under Sultan Ali ibn Yusuf. It was reinforced in the 13th century with a barbican, partially demolished during the 1868 Revolution, and rebuilt without its white plaster. Since 1908 it has been listed as a Bien de Interés Cultural with the city walls.

Locals call it torre de la tía Tomasa, a nickname that has stuck alongside the official name. The name Torre Blanca comes from the white paint that once covered its mortar and brick walls; after the 1868 demolition and rebuilding, the white rendering was not renewed. Eight smaller, simpler towers still line the surviving stretch of wall beside it.

Torre Blanca stands on the Ronda Histórica, on the stretch of wall between the Puerta de la Macarena and the Puerta de Córdoba. The tower and its wall panel, with the barbican and eight smaller towers, are seen from the street; there is no interior visit. Look for the brick and rammed-earth masonry and the octagonal plan from the pavement.

Locals also call it the tower of Aunt Tomasa (torre de la tía Tomasa), a nickname that has outlasted its original white paint. Of the four defensive towers of Seville's wall — with the Torre del Oro, Torre de la Plata and Torre Abd el Aziz — it is the only one that still keeps its stretch of wall, along which eight smaller, simpler towers stand.
