Over time, the Provincial Administration became increasingly aware of the importance of recovering the historic premises of the palazzo. And so, between 1911 and 1929 the Councillor Arturo Linaker launched a series of operations of reclamation and restoration designed and directed by the architect Enrico Lusini with the intention of, where possible, dismantling the superstructures and modifications imposed by the administrative purposes for which the premises had been used.

In 1929, in the ground floor rooms looking onto Via de’ Gori – now museum display rooms – the Museo Mediceo was opened, with documentary material designed to illustrate the individual figures and the customs of the Medici dynasty. This initiative culminated in 1939 in the Mostra medicea, an important exhibition which focused attention on the patronage of the illustrious dynasty which had marked the destiny of Florence and Tuscany for so many centuries.
In the meantime, in 1938, a sumptuous banquet was held in the Riccardi Galleria on the first floor, in honour of the visit of Hitler accompanied by Mussolini to Florence, attended by the Florentine aristocracy.
In 1942 the Minister Giuseppe Bottai officially reopened Riccardiana and Moreniana libraries, which had been closed after the First World War.
