On 30 April 1651 in Wiener Neustadt, she became the third wife of Emperor Ferdinand III and they parented four children. Eleonore supported religious orders and, in 1663, founded the Ursulinen convent in Vienna. She was elected patron of a Carmelite order, founded in 1662 in Wiener Neustadt, as well as of an order named 'Sklavinnen der Tugend' (female slaves of virtue, for noble ladies). In 1668, to celebrate the survival of a convent from a huge fire, she was involved in the forming of the 'Sternkreuzorden', also meant for noble ladies from Austria as well as from foreign countries. 

Eleonora was a highly intelligent woman with literary and musical interests, whereby she did not discriminate against protestant authors. She became the centre of a literary academy founded by her 
husband on an Italian model. In 1657 she became a widow but remained the centre of the Imperial court of her stepson, Emperor Leopold I, gave parties, had comedies and ballets performed and wrote Italian poems mainly with religious contents. Aged fifty-six she died in Vienna on 6 December 1686.
