Forests of the Iberian Peninsula blackberry bushes, blackthorn, hawthorn and other more or less thorny shrubs; this role can also be filled by smaller thorny plants, "los piornales", and clumps of broom. The major forests in this area are beech, oak, birch, and fir. Beech forests ("Fagus sylvatica") are found in the mountain layer of the Iberian Eurosiberian region from 800 to 1500 metres up. The soil is cool, as often chalky as siliceous (rich in silica), and nearly always acidified by rain. The layer is characterised by the beech tree. The beech tree projects a deep shadow, and so its dense foliage usually excludes

However, in the Turbine factory the corners are covered by heavy elements that slant inside. The glass surfaces also slant inside and are recessed in relation to the piers. The load-bearing elements are attenuated and the building has an image of stability and monumentality. In Fagus exactly the opposite happens; the corners
