Battles of the Isonzo
The Kostanjevica monastery was severely damaged in the Battles of the Isonzo during World War I. It was restored between 1924 and 1929. Until the end of World War II, the monastery was part of the town of Gorizia. In 1947, the border between Italy and Yugoslavia was set just a few hundred meters westward from the monastery, and Kostanjevica became part of the newly established town of Nova Gorica.
