The building originally housed the Piccardi houses and the Locanda Grande, accommodation for passing foreigners, then in 1780, by order of the shopkeeper Domenico Plenario, the architect Ulderico Moro designed a building in the Triestine neoclassical style with baroque influences and rococo. In 1801 the palace was bought by Giovanni Lovovitz. In 1834 the entire property passed to the scholar Riccardo Pitteri. In 1880 the Caffè Flora was opened on the ground floor at the behest of Giuseppe Mander. During the day the Café was the meeting place for the choristers of the Verdi theater, located adjacent to the Piazza, while at night it was frequented by the proletarian inhabitants of Cittavecchia. In 1982 the architects Celli and Tognon made a general renovation of the building. The building later became the property of the Lloyd Adriatico insurance company.
