This neoclassical mansion was designed by architect Tilman-François Suys in 1840. It is the last of the original buildings in this block, having only undergone a few alterations in 1909. The building was bought on 7 November 1919 by Rodrigo de Saavedra y Vinent, Marqués de Villalobar, on behalf of the Spanish government, which he represented as Minister Plenipotentiary to Belgium. It was intended for the Spanish Legation in Brussels. Today, it houses the Spanish Ambassador to Belgium's official residence. The interior has retained an elegant decorative scheme as well as some artworks from the Marqués de Villalobar's collection. The entrance hall's grisaille painting depicting the Santa Cruz Palace in Madrid and also the bronze sconces illuminating the magnificent banister, as well as a reproduction – executed by a Belgian artist and located in the stairwell – of the coat of arms of Toledo adorning that city's Puerta de Bisagra Nueva (New Bisagra Gate) all date from this period.
