During the course of the war many churches in Württemberg were looted and became stripped of their ornaments, especially following the battle of Nördlingen in 1634. Antonia made it her mission to establish foundations to repair and restore the churches. Her charity, piety, gift for languages and all-encompassing scholarship were widely praised, and she became celebrated as "Princess Antonia the learned", and "the Minerva of Württemberg". Wherever possible she dedicated herself to the arts and sciences, together with her two sisters the princesses Anna Johanna and Sibylle.
