Close to the castle, the "Parlement de Navarre" of Navarre, so named, saw its origins in the annexation of Béarn to the Crown of France under Louis XIII in 1620. Though, in fact, he established himself in a very old courthouse that had been built as early as 1585 in place of the house of the Bishop of Lescar. Burned down in 1716, it was rebuilt but quickly abandoned in favour of the current courthouse. The General Council settled there and it still holds its sessions.
