Demolished and transformed into a residential home, it still maintains some stylistic and decorative elements. It is a building of noble bearing and great beauty whose most remarkable element is the beautiful shield carved in stone that it has on its façade and which belongs to the Mujica-Butrón lineage, dated 1603, to which the previous building also belonged.
The Shield is engraved with an inscription in Basque erected in the possibly oldest epigraphic text that is preserved in this language:
“MUXICA ARERIOCAZ AGICA BUTROE CELANGOA DA OROC D // AQUIE GARAIA NAGO ERIA GORDE AGO”.
“Mujica bites into the enemies Butron as he is, everyone knows that I am the winner. People be on your guard.”
