city, capital of Segovia provincia (province), in the comunidad autónoma (autonomous community) of Castile-León, Spain, northwest of Madrid. The site of the expansive medieval Alcázar palace and the famous Segovia aqueduct, the city was added to UNESCO's World Heritage List (World Heritage site) in 1985.

There are two well-differentiated areas in Segovia: an upper town encircled by ancient walls, situated on the narrow limestone ridge between two small rivers, the Eresma and the Clamores; and a lower part outside the walls. The centre of the old town is the Plaza Mayor, site of the 16th-century Gothic cathedral, from which streets lead into the outer suburbs. Crossing the Plaza del Azoguejo, the focal point of traffic, is the Roman-built Segovia aqueduct, popularly known as El Puente, one of the finest and best-preserved examples of its kind. It carries water 10 miles (16 km) from the Frío River to Segovia.

Notable churches include those of San Esteban (with a superb tower), San Martín, La Trinidad, San Lorenzo, and San Millán. They are all Romanesque, and all date from the 12th century. The Church of Vera Cruz (13th century) formerly pertained to the Knights Templars (Templar); it contains murals and other artwork dating from the late 15th century. The Romanesque Church of San Justo is notable for its 12th-century paintings.

The Alcázar, mention of which was recorded as early as the 12th century, commands the city from the ledge above the river. It was the fortified palace of the kings of Castile; Isabella (Isabella I) was crowned queen there in 1474. The original building was mostly destroyed by fire in 1862 but was subsequently extensively restored.
