Today we’ll explore nearby Siena, a beautifully preserved medieval city in Tuscany, renowned for its stunning Gothic architecture, deep-rooted history, and as the home of Saint Catherine of Siena, a revered 14th-century mystic. We’ll have a half-day walking tour including the Basilica of San Domenico (housing Catherine’s relics), the Siena Cathedral, the Piazza del Campo, and many of Siena’s medieval streets. After lunch (on your own), you’ll be free to explore those streets and find your own favorite corner of Siena. Return to Florence for a casual pizza dinner (included) and overnight at Hotel delle Nazioni, Florence.
