American professor Edward Wallace Muir Jr. said on Palmanova: "The humanist theorists of the ideal city designed numerous planned cities that look intriguing on paper but were not especially successful as livable spaces. Along the northeastern frontier of their mainland empire, the Venetians began to build in 1593 the best example of a Renaissance planned town: Palmanova, a fortress city designed to defend against attacks from the Ottomans in Bosnia. Built ex nihilo according to humanist and military specifications, Palmanova was supposed to be inhabited by self-sustaining merchants, craftsmen, and farmers. However, despite the pristine conditions and elegant layout of the new city, no one chose to move there, and by 1622 Venice was forced to pardon criminals and offer them free building lots and materials if they would agree to settle the town."
