The Castello della Magione (also Magione di San Giovanni al Ponte or Spedale di San Giovanni in Gerusalemme alla Magione) is a medieval castle in Poggibonsi (province of Siena, central Italy). It is an example of a medieval "Mansio" (residence) that belonged to the Knights Templar. The castle includes the ancient church and the “spedale” (hotel) for the pilgrims in transit to Rome on the Via Francigena.
