Eleonore Batthyány-Strattmann never remarried but was Prince Eugene of Savoy closest companion and some have said mistress. Eugene was, for the last twenty years of his life, a guest at Rechnitz Castle as well as Eleonore's Vienna palace which was very close to his Winter Palace. Eugene and Eleonore met almost every day till his death in 1736. Prince Eugene had known the Strattmann family for years, as he and Eleonore's father, the court chancellor, had, incidentally, arrived in Vienna at the same time in 1683. It is not known precisely when their relationship began, but his acquisition of a property in Hungary after the Battle of Zenta, near Eleonore's Rechnitz Castle, made them neighbours.
