Its narrow and steep cobblestone streets, whitewashed houses, and finely crafted wrought-iron window grilles make Arcos the quintessential Andalusian pueblo blanco. Make your way to the main square, the Plaza de España, the highest point in the village; one side of the square is open, and a balcony at the edge of the cliff offers views of the Guadalete Valley. On the opposite end is the church of Santa María de la
Asunción, a fascinating blend of architectural styles—Romanesque, Gothic, and Mudejar—with a plateresque doorway, a Renaissance retablo (altarpiece), and a 17th-century baroque choir. The Ayuntamiento stands at the foot of the old castle walls on the northern side of the square; across is the Casa del Corregidor, onetime residence of the governor and now a parador. Arcos is the westernmost of the 19 pueblos blancos dotted around the Sierra de Cádiz.
