Constructed of cream-colored travertine, the oldest of the abbey’s chapels is believed to have been founded by the Holy Roman Emperor Charlemagne, though its apse, frescoed radial chapels, and cloisters were completed centuries later. The Romanesque facade is carved with figures of the Apostles, while the stately bell tower is decorated in Lombard style. Thanks to its proximity to the Via Francigena pilgrimage route between France and Rome, Sant'Antimo was one of the most powerful Benedictine abbeys in Tuscany before Pope Pius II closed it in 1462. During its deconsecrated years, the church was used as a wine cellar and a cow shed, becoming an active place of worship again only in 1992.
The Abbey of Sant'Antimo is a popular stop on day trips to Tuscany from Rome, Florence, and Siena that explore the countryside surrounding Montalcino, Montepulciano, Pienza, and San Quirico d'Orcia. One-day sightseeing tours generally include lunch with a tasting of local Brunello di Montalcino wine.
