Before World War I Gradisca d’Isonzo/Gradišče belonged to Austria-Hungary. When the war broke out, some inhabitants volunteered for the Italian Army, because they thought this land should belong to the Kingdom of Italy. Others joined the Austro-Hungarian Army. To commemorate the soldiers of Gradisca who fought on the one or the other side, there are two monuments in the park between Viale Regina Elena and Via Gorizia.
The Altar (Ara) is dedicated to the soldiers of Gradisca who fought on the Italian side. On one side of the Altar there are five names of soldiers, including Antonio Bergamas, on the other side there is a long inscription signed by General Armando Diaz.
The Column with ninety names in alphabetical order is dedicated to the soldiers of Gradisca that fought for Austria-Hungary in the years 1914‒1918.
The park with the monuments is located between the streets Viale Regina Elena and Via Gorizia.
