The Batzoki is a key work of Basque, Spanish and European rationalist architecture because there are very few preserved examples of modern style political seats.
The architect Ispizua applied an expressionist rationalism of great plastic strength and an impressive presence. To achieve this, he used the curved chamfer treatment and the accentuation of the angle with the arrangement of a stolen body, in order to create an iconic image. The other aspects to be highlighted are: the contrast of horizontality and verticality, the large horizontal openings, the curved bars on the ledges, the flat roof as a garden terrace and the cantilevered arrangement of the belvederes, floors and staircase bodies, to reinforce the expressionist condition of the project.
