The application was created for the occasion of marking the centennial since the beginning of the First World War in Serbia, also known as the Great War, which lasted from 1914 to 1918. Although the application does not contain information about a large number of monuments, they represent a true testimony of the culture of remembering people and events that changed the world during the second decade of the 20th century, as well as ideas that reached the peak during the war, and how they came to realization right after the ward ended.
