Arcos de la Frontera is one of the Pueblos Blancos, white hilltop villages in Southern Spain.
Archaeological remains from the Neolithic, Bronze, and Roman ages have been found; it became an independent Moorish principality in 1011, and the Gothic cathedral was constructed in the 1200s.
This National historic monument is a tangled labyrinth of narrow cobbled streets and alleys, a joy to walk.
