The Abbey of Saint Galgano was a Cistercian Monastery found in the valley of the river Merse between the towns of Chiusdino and Monticiano, in the province of Siena, region of Tuscany, Italy. Presently, the roofless walls of the Gothic style 13th-century Abbey church still stand. Nearby are the chapel or Eremo or Rotonda di Montesiepi (1185), the tomb of Saint Galgano and the purported site of his death in 1181, the sword said to have been planted in the ground by Galgano and a chapel with frescoes by Ambrogio Lorenzetti.
