The Roman road of the Puerto del Pico Monument · Cuevas del Valle, Arenas de San Pedro, Ávila Image of Cuevas del Valle, not of the place itself. The Puerto del Pico causeway climbs in zigzags up the southern slope of the Puerto del Pico pass, in the Sierra de Gredos, between the municipality of Cuevas del Valle and the pass itself, with a cobbled surface in overlapping layers and a width of between 5.5 and 8.5 metres. The pass, at 1,395 metres above sea level, links the Tiétar valley with the Alberche valley and was once part of a route between Santiago de Compostela and Seville, already described around 1380 in the Bruges itinerary; today it is a crossing point on the Cañada Real Leonesa Occidental. Despite the tradition attributing it to Roman times, current studies consider that dating incorrect. It was restored in 1998 with European funds.
