Palazzo Margherita, formerly Palazzo Piombino, is a palazzo on Via Veneto in Rome. The usual name references Queen Margherita of Savoy, who lived there from 1900 to 1926. In 1885, the Boncompagni-Ludovisi family chose to sell their ancestral family home in response to a severe financial crisis. The Villa Ludovisi and most of its extensive grounds were sold in 1883 to a property developer, the Società Generale Immobiliare, which in 1885 divided the property into luxury building lots. The family retained a small portion of the original estate around the Casino di Villa Boncompagni Ludovisi (Villa Aurora), the only building from the original holdings that was not demolished. However, the Casino was not designed to be the primary family home of a noble family. The Palazzo Piombino was built from 1886 to 1890 by Gaetano Koch for Rodolfo Boncompagni Ludovisi, titular Prince of Piombino, as a new palace for the Boncompagni-Ludovisi family. It occupied one of the new developer lots at a prominent location along the Via Veneto, the new main road that developers had built through the former Villa property. The Boncompagni-Ludovisi family occupied the house for barely a decade before being forced to sell it in 1900 due to further economic difficulties, including some due to the high cost of the new palazzo itself. After the assassination of King Umberto I in Monza in 1900, his son and successor King Victor Emmanuel III purchased the palazzo from the family as a suitable residence for the newly widowed Queen Margherita, who took up residence in the palazzo on Christmas Day, 1900 for the remaining 26 years of her life. She remained active in public life in her roles as queen dowager and queen mother, and the building in which she lived become known as Palazzo Margherita. After her death, the building was divided into offices for the Mussolini government. In 1946, the US government purchased the palazzo from the Italian government, and it now houses the United States Embassy in Italy. The palazzo was extensively renovated between 1949 and 1952 to restore rooms to their earlier appearance, while also modernizing plumbing and heating systems and increasing office space. The palazzo is now protected both by Italian law for cultural heritage and by listing on the U.S. Department of State Register of Culturally Significant Property.

Judith Beheading Holofernes is a painting of the biblical episode by Caravaggio, painted in c. 1598–1599 or 1602, in which the widow Judith stayed with the Assyrian general Holofernes in his tent after a banquet then decapitated him after he passed out drunk. The painting was rediscovered in 1950 and is part of the collection of the Galleria Nazionale d'Arte Antica in Rome. The exhibition 'Dentro Caravaggio' Palazzo Reale, Milan (Sept 2017-Jan 2018), suggests a date of 1602 on account of the use of light underlying sketches not seen in Caravaggio's early work but characteristic of his later works. The exhibition catalogue (Skira, 2018, p88) also cites biographer artist Giovanni Baglione's account that the work was commissioned by Genoa banker Ottavio Costa. A second painting on the exact same subject (see below) and dated to 1607, attributed by several experts to Caravaggio but still disputed by others, was rediscovered by chance in 2014 and went on sale in June 2019 as "Judith and Holofernes".
