On the night of July 15, 1576, Isabella de' Medici, daughter of the all-powerful Cosimo I, grand duke of Tuscany, was murdered by her husband in the Villa Medicea in the town of Cerreto Guidi for "reasons of honor"—that is, she was suspected of adultery. These days, although the villa's formal garden is in somewhat imperfect condition, the vast halls and chambers within remain majestic. Copies of portraits of various Medici, including Isabella, cover the walls. The villa sits atop the highest point in Cerreto Guidi, encircled by two narrow streets where the daily business of the town goes on. As you stand on the wide, flat front lawn, high above the streets of the town, with the villa behind you and terraced hillsides of olive groves and vineyards stretching into the distance, you can imagine what it was like to be a Medici. To see the villa, ring the bell for the custodian.
