On 8 August 1937 a large labor fair was held in Dobrunje on St. Ulrich’s Hill, organized by the Yugoslav Professional Association (, JSZ). It was attended by over 2,000 people. In 1942 two men from Bizovik (Franc Jakoš and Janez Pavčič) and three from Dobrunje (Milko Cankar, Franc Jakoš Sr., and Franc Jakoš Jr.) were abducted and killed by the Partisans. They were referred to in the extensive press coverage as the "Bizovik victims" () and the "Dobrunje victims" (). Their bodies were discovered on 20 March 1943 and they were buried at the Bizovik and Dobrunje cemeteries in ceremonies attended by several thousand people. During the Second World War, a White Guard post was located at St. Ulrich's Church above Dobrunje. White Guard forces allegedly killed 123 people at the site, using the rectory basement to torture their victims. Soon after the war, reports about murders at St. Ulrich's started to appear in leftist emigrant newspapers such as "Enakopravnost", with some claiming that over 700, 1,000, or even 1,500 people had been killed there. Local people were forced to disinter bodies for three weeks and bury them in a mass grave. A memorial by the architect Boris Kobe and the sculptors (1910–1959) and (1911–1990) was designed between 1948 and 1951, and was installed at the site in 1955. The mass grave memorial officially contains the remains of 123 victims of the White Guards, 36 members of the fourth battalion of the Partisan Cankar Brigade killed in an attack on 18 September 1943, and the poet, playwright, and Partisan soldier (1902–1943). The memorial complex also includes two beech trees in the forest south of the church where it is alleged that victims were shot. After the fall of communism and Slovene independence, local people started openly calling into question the official version of events at St. Ulrich's. Claims were made that many of the bodies at the site were actually people liquidated by the Partisans during or after the war, including the "Šentpavel victims" ()—eight men abducted by Yugoslav military police (KNOJ) from the village of Šentpavel on 4 July 1945 and murdered. It was also suggested that the political commissar Ivan Maček (1908–1993) manipulated the facts in order to create a major Partisan memorial conveniently located near Ljubljana.
