The Casa de Juntas (Assembly House)
The Tree of Gernika and the Casa de Juntas (Assembly House)
An exquisitely beautiful neoclassical building imbued with the living history of the Basque People.
For centuries, Gernika has been a meeting place for the people of Vizcaya.
Documents attest to meetings taking place under the now famous tree as far back as the 14th century. Their purpose was to draw up a set of laws based on a system of citizen representation. A visit to the Casa de Juntas and the Tree of Gernika is therefore an absolute must, given that they are living symbols of the history of the Basque People.
The Assembly House stands next to the so-called ‘foral’ (charter) oak tree, a meeting point for all the territories of Euskal Herria, united in a single cultural and ethnographic tradition that transcends any manner of political division. Today it is the venue for such important ceremonies as the swearing-in of the Lehendakari or the Governor of the Regional Government.
The history of the Tree of Gernika
During the early years of the Lordship, the inhabitants of Bizkaia used to gather in assemblies held in the shade of various oaks located in different places in the region. However, over time, they adopted the practice of meeting in one unique place and under a single tree: the Tree of Gernika.
What will I see inside the Assembly House?
The Guernica Assembly House is in fact a Church and a Parliament. Although the building’s ecclesiastical facet takes second place to its political facet today, it retains both the altar and the holy water fonts as silent witnesses to days gone by.
La Sala de Juntas (The Assembly Room)
A series of canvases grace the inner walls of the Plenary Hall:
- On the one hand, there is a gallery of portraits of the Lords of Vizcaya, painted by Sebastián de Galbarriartu and the Bustrín brothers in the 17th century. Each portrait is crowned by a panel bearing the dates on which certain Lords of Vizcaya swore to uphold the Fueros.
- On the other, two paintings depicting the swearing-in of the Lord of Vizcaya in Gernika:
- “The Citizens of Vizcaya Line up to Kiss the Hand of Ferdinand V in 1476”, painted in 1609 by Francisco de Mendieta. It illustrates the setting in which the Assemblies originally took place. It is also a valuable ethnographic testimony of the clothing worn by the people of Vizcaya at that time.
- “The Swearing-in of a Lord of Vizcaya”, painted in 1882 by Anselmo de Guinea.
All these elements reflect both the fact that the Lord of Vizcaya did indeed wield authority and that he was under an obligation to swear an oath to uphold and abide by the set of laws that the community had drawn up on the basis of custom and usage (the Fueros).
The Stained-Glass Room
In 1964, this space, which the architect originally designed as an uncovered courtyard, was transformed into a museum dedicated to the history of Vizcaya. Following the restoration of the General Assemblies, the House regained its significance, and the hall was once again reserved for the institution’s own uses.
The most spectacular feature of this room is the spectacular stained glass window that also serves as the roof. Installed in 1985, it was made by hand by Vidrieras de Arte S.A., a company based in Bilbao. It is the largest such work that they have undertaken to date. It offers a graphic illustration of the symbolism of the tree as a meeting point for the different municipalities of Vizcaya.
An interpretation of the stained glass window
- In the centre, the Oath Stand and the tree refer directly to the early assemblies; next to them, an inscription, “Lege Zaharra”, bears reference to the ancient laws that the Lord had to swear to uphold.
- References to the economic activities of the Territory.
- The central section is encircled by a border containing the most representative monuments of the different towns in Vizcaya.

Is the Assembly House still in use today? What is it used for?
Such important events as the swearing-in of the Lehendakari (President of the Basque Government) and of the Governor of the Regional Government of Vizcaya are held in the Assembly Hall and in front of the Tree. In this respect, on a nearby monolith, a plaque commemorates the words spoken in 1936 by José Antonio Aguirre to formalise his oath as the first Lehendakari, words that have become part of the protocol for his successors.
It is also used several times a month as the venue for the extraordinary plenary sessions of the General Assemblies of Vizcaya.
