In December 1701, the Consell General bought the Casa de la Vall and moved into it in the following year. The building was not only a place for meetings and a focus point for the representatives of the parishes ? the Andorran territorial divisions, where they dealt with matters affecting the territory of the valleys, but was also used as a seat of justice, as we read in the inscription of the shield over the main door, ?... Iustitia sedes?.
All the functions of the Andorran government, administration and justice took place in the same building. The needs of growth meant that other premises had to be used and led to the building in 2011 of a new home for the parliamentary institution.
