Nonetheless, the visitors were allowed access to the upper part of the park and, from 1931, to the "Castelletto", furnished with Archduke Maximilian’s fittings which had not formed part of the Duke of Aosta’s furnishings. Afterwards the castle was used as a school for officers by the German troops who occupied the city. As a result of the opposition of the Gauleiter Friedrich Rainer to the conversion of the castle into a Nazi headquarters the building was saved from the possible danger of bombardment. In the meantime, the furnishings had been removed and were kept in various buildings in the city.
