The Mausoleum of Yugoslav Soldiers (Czech: Mauzoleum jugoslávských vojínů or also Jihoslovanské mauzoleum) is a neoclassical chapel with an ossuary containing remains of soldiers from what later became Yugoslavia killed in the First World War. It was built in 1926 in Bezruč Park in Olomouc, Czechoslovakia (now the Czech Republic) by the Czechoslovak-Yugoslav League. The designer of the chapel was architect Hubert Aust.[1] The mausoleum was owned by Yugoslavia until its breakup. It was in bad shape for long time. Its renovation was prevented because of unclear property rights.[2] The chapel was reconstructed in 2016–2020. The mausoleum is now owned by the city of Olomouc. (A Czech court took it away from Yugoslavia. The reason was that the Kingdom of Yugoslavia had ceased to exist, and none of the former Yugoslav countries wanted to look after it.)[3] Another, larger Mausoleum of Yugoslav Soldiers in the Czech Republic is in Jindřichovice (near Karlovy Vary). There are 7,378 bodies interred there.
