Palazzo Canevari

Roma Capitale's tourism portal records that the palazzo was wanted by Quintino Sella to house the Regio Ufficio Geologico and its Museo Agrario-Geologico, and was built between 1873 and 1881 to the design of the engineer Raffaele Canevari. Canevari reused seventeenth-century masonry and built exhibition rooms carried on cast-iron piers, with a gallery over a large reading room. It was inaugurated on 3 May 1885 in the presence of King Umberto I. Roma Capitale's tourism portal describes the palazzo as considered among the first examples of 'stile liberty' in Italian public building.

It housed the Geological Institute and the museum collections until 1995, when it was closed. There is no public access. According to Italian Wikipedia's infobox, which cites nothing, the building is under refurbishment and is owned by Cassa depositi e prestiti.

On the address: Roma Capitale publishes it as Largo di Santa Susanna 13, and Italian Wikipedia says that square lies partly in the rione Sallustiano and partly in Trevi. This guide claims the building, which boundary tests put inside Sallustiano, and not the square, which is claimed here for no rione at all.
