Palazzo dei Marescialli, Rationalist palace in Castro Pretorio district, Rome, Italy

The Palazzo dei Marescialli is a rationalist administrative building located on Piazza dell'Indipendenza, featuring clean geometric lines and functional architecture. The structure spans multiple stories with facades that emphasize symmetry and ordered design principles.

The palace was built between 1879 and 1881 for senator Giacomo Astengo to a design approved in June 1879, on the new Piazza dell'Indipendenza. In 1920 Enrico Castelnuovo bought it and had Enrico Paniconi enlarge it by merging the neighbouring Villino Castelnuovo, works finished in 1923. In 1937 it was chosen as seat of the Marescialli d'Italia, and after expropriation in 1939 it passed to the state.

The building has housed the Consiglio Superiore della Magistratura since 1962. Its main hall, the Aula Bachelet, holds four gilded carved reliefs depicting stories of Marco Polo by Romano Rui. The neighbouring Villino Castelnuovo, bought by the council in 1985, has ceiling paintings of gilded stucco, rose pergolas and coloured coffers.

The building is accessible during weekdays but requires prior authorization due to its governmental role. Visitors should plan according to standard office hours and contact the administration in advance.

The name honours Vittorio Bachelet, the CSM vice-president killed by the Red Brigades in 1980; the renaming took effect on 12 February 2024. Inside, the main hall called Aula Bachelet holds four gilded carved reliefs telling the story of Marco Polo, made by Romano Rui.
