Castelnuovo hosted many important figures in history. Written on a note dating back to the end of the forties and found in the villa, was a list of some personages who were accommodated at the Castelnuovo villa. The owners of that time, who had turned Castelvecchio in a sort of agriturismo namely, a rural holiday retreat, as if to excuse themselves for the state of deterioration of the building, put up a notice at the entrance of Room n. 3 which read:

"Dear Guest, we apologise for the scanty furniture and the poor service. For the good reputation of this TOURIST - SOCIAL CENTRE, managed by the CASTELNUOVO AGRITURISMO-SPORTING CLUB - a non-partisan, apolitical, intellectual and physical wellness club, for youth individual or group travelling and tourism, we kindly ask you to help us maintain maximum cleanliness and morality. Over the centuries, Castelnuovo has been ransacked several times and the original pieces of furniture have been either destroyed or stolen. However, do consider that with the same defectiveness, these rooms have accommodated:

  • The VASSAL COUNT RAYMOND VI della TORRE-HOFFER who started the construction of Castelnuovo in 1556. He was also known as Raymond the Elder.
  • The VASSAL COUNT RAYMOND IX della TORRE-HOFFER who completed the works of the Villa giving it the appearance we can admire today. He built the surrounding wall and the circular tempietto standing in the front garden of the Villa to honour his wife, the Baroness of Valburga who had died in 1821. Raymond IX lived at Castelnuovo from 1780 to 1817, taking refuge in Ljubljana during the intermediate period of Napoleon's invasions.
  • THE PRIORESS ELEANOR DELLA TORRE
  • PRINCESS THERESA DELLA TORRE VALSASSINALA PRINCIPESSA TERESA DELLA TORRE VALSASSINA

  • GENERAL EUGENE DE BEAUHARNAIS, on the 5-10-1813. General Beauharnais appointed viceroy of Italy on the 7-6-1805, was born in 1781 and died in 1824.

  • KING VICTOR EMANUEL III OF SAVOY. He stayed here after the Second Battle of the Isonzo also known as the Battle of Monte San Michele (18 July - 3 August 1915).
  • BENITO MUSSOLINI - Prime Minister of Italy from 1922 to 1943. He was accommodated here for the Memorial Ceremonies to commemorate the fallen held in Redipuglia. Benito Mussolini was born in 1883 and was shot dead in Dongo, on Lake Como, in 1945 together with CLARETTA PETACCI, who occupied the room next door.

Moreover, on page 75 of the book written by Bottar Serafico - La memoria di Rainer Maria Rilke e l'archivio del Castello di Duino, Editoriale Lloyd (Memories of Rainer Maria Rilke and the Duino Castle Archives), we read the following note:

"As a child, Marie had the chance to meet the young Liszt who, in 1869, was a guest in Sagrado for a couple of days. Here, on their "small modest Pleyel", he played the improvisations on the Viennese themes he had performed for Napoleon III and one afternoon he was heard practicing a sonata by Beethoven in the white boudoir."
