Mantua and Sabbioneta, a UNESCO World Heritage site in Italy, exemplify Renaissance urban planning and architecture. Mantua, a historic city, boasts grand palaces, churches, and piazzas shaped by the influential Gonzaga family, while Sabbioneta, a nearby 'ideal city,' features a meticulously designed grid layout with fortified walls and notable structures like the Teatro all’Antica. Together, they illustrate the artistic and political vision of the Renaissance era.
