Armentia was a Spanish village in Álava, Basque Country and is at present one quarter of Vitoria-Gasteiz as a result of the city's expansion.

The village of Armentia was the most important religious centre in Álava in the late Middle Ages[2] and as it was the see of the bishop, its church was the first cathedral in the Basque Country until the end of the 11th century, a time when the southern part of the Iberian Peninsula was dominated by Muslim forces.

On the ridges you can find beech, holly and rowan and along the edges of the small streams that flow through the park, maple, hazel and ash are very common.

In 1974, the Provincial Council of Álava, the owner of this land, began work to improve the gall oak wood and thus initiated the creation of a botanical park in the deforested areas, including native species together with other, more exotic plants and trees.

In the mid-90s, the wood showed clear signs of degradation such as the accumulation of rubbish, remains of bonfires, and excessive number of pathways and tracks and numerous eroded and flooded areas.

Work to maintain the wood has been and continues to be a key contributing factor to the healthy state of conservation that is apparent today in Armentia park.
