Zambrana

Historically it was a hamlet contingent under the jurisdiction of Beraventilla's villa until 1744 when Felipe V gives it the title of villa.

In the urban area of Zambrana stand out some illustrious houses, the church of Santa Lucía and the Transept.

Portilla had in its boundary an important castle during the Middle Ages, remains of which can still be found in the hill situated over the locality. From there one can enjoy nice panoramic views composing an excellent place to make a small excursion.

The importance of Portilla's castle was such that its tower was used as central motive of Álava's shield. A document from 1294 shows a stamp that was used as base for the shield of the " Very Noble and very Loyal Province of Álava". A popular legend also tells us about the castle and says that there is a place from where one may see seven rivers, below it there is an exceptional treasure: the golden bull. The environs of Portilla's castle constitute a place of great natural beauty to enjoy an excursion day.

In leisure, crowning the upright profile of the cliff named Lanos, raise the remains of the ancient fortress of which are partially preserved the large fortified tower and the barbican that were closing it. It was the main defence of this area in medieval times. From this position one of the busiest routes during this period stands out above.

In Berganzo the Sarmiento family built a tower; later upon its rests was built the church of San Miguel, which has a nice altarpiece of Romanist style.
