We continue our journey of the two oldest houses in Marseille, going to the Panier district, behind the Town Hall, in the 2nd Arrdt of Marseille, at 2 rue de la Prison, in front of the Maison Diamentée . This building, of great architectural beauty, drawn from the style of Medici Italy, originated from being the former hotel of Saboulin Bolleng, which dates from the year 1570 and its name comes from the aspect of its facade, which is covered with stones cut into diamond points or also called prismatic bossage. This old hotel was built on the grounds of the former gardens of the Palais de Provence, at the request of wealthy sponsors, Spanish and Italian merchants, during the great Mediterranean trade. It was home to large Marseille families including that of Pierre Sebolin de Bollena, 2nd alderman, in 1683, his nephew François de Saboulin Bollena, 1st alderman, in 1702, the Castellane Majastre. Then occupied by Italian families, in transit. According to oral tradition, this building would be the Palace of King René, Count of Provence. In 1914, the cultural association Art et Charité bought the hotel which was in ruins, and bequeathed it, for its preservation, to the Vieux-Marseille Committee. In 1925, the hotel was listed as a Historic Monument. During the occupation, in 1943, the Germans, from the Nazi regime, decided to raze the Panier district, which was, in their eyes, an uncontrollable quagmire. The January 3 operation aims to reshape the neighborhood whose alleys are considered dangerous. In fact, the population was rounded up and evacuated to concentration camps, and the neighborhood methodically searched before the houses were dynamited. Hitler's orders - the Old Port must be razed. Fortunately, the perimeter destroyed will be less than that initially set. Demolition begins on February 1st and continues until the 19th of the month, sparing few historic buildings. The Hôtel de Cabre and the Maison Diamantée are among these spared buildings. In 1962, the Old Marseille Committee donated the hotel to the City, with its collections and library. The Museum of Old Marseille was installed there from 1967 to 2009, then its collections were integrated into the Marseille History Museum. In 2013, the hotel was occupied by the Marseille Provence, European Capital of Culture association. In 2015, the hotel was classified as an administration office for Municipal Services, to the great disappointment of the Old Marseille Committee, which requested, in 2019, a retrocession, to preserve its cultural vocation, but which has not yet come to fruition. Discover its magnificent staircase, at the entrance, with its surprising decor.
