The town of Vejer de la Frontera occupies a low hill overlooking the Straits of Gibraltar and surrounded by orchards and orange groves. It contains several ancient churches and convents, and the architecture of many of its houses recalls the period of Moorish rule, which lasted from 711 until the town was captured by Saint Ferdinand of Castile in 1248. Agriculture and fruit-farming are the chief industries; fighting bulls are also bred in the neighborhood and a running of the bulls is held annually.
