By that time, the states and properties of the House of Savoy where recovered; during Maria Anna's absence, the Palazzo Chiablese was used by Camillo Borghese, 6th Prince of Sulmona and his wife, the famous Pauline Bonaparte.

[6] However, Maria Anna didn't return to her homeland immediately: in 1820 she acquired the Villa Rufinella in Frascati near Rome, having bought the property from Lucien Bonaparte.

In 1822, despite protests from her brother and cousin, Maria Anna settled in Florence, despite the fact that the city actively participated in the period of unrest in the Kingdom of Sardinia the previous year.

[1] Only at the beginning of 1824 Maria Anna returned to Piedmont, where in the Castle of Moncalieri meet her brothers, the former King Victor Emmanuel I and the new monarch Charles Felix.

She bequeathed all her properties, including the Palazzo Chiablese, the Ducal Castle of Agliè and the Villa Rufinella in Frascate, to her brother Charles Felix.
