The same year , on Christmas , Josip Jelačić 's wife - countess Sofia , gave birth to their daughter Anica on the estate , for which occasion , the banner was raised on top of the manor . However , little Anica soon died as an infant so Jelačić had her body buried Inside St. Joseph chapel . He also planned to build the family tomb on the estate , but died in 1859 , before being able to execute this . In his last will , he expressed a wish to be buried next to his daughter in the estate chapel . After the death of Josip Jelačić , the estate became the property of his brother Đuro , who continued managing it and finally completed tomb wished by Josip in 1884 . The design for this was made by prominent Austrian architect Hermann Bollé . The construction of the tomb was made out of unused stone , taken from reconstruction of Zagreb cathedral , which was badly damaged in 1880 Zagreb earthquake . After Đuro 's death , the castle was inherited by his daughters Anka and Vera . In 1919 . countess Vera Jelačić donated the family collection of weapons and paintings from Novi dvori , to what was then Croatian People 's Museum . The daughters bequeathed the estate to the Croatian people in 1934 . Although Đuro , Hermina , and much of the Jelačić family were initially buried in family arcade in Zagreb 's Mirogoj cemetery , their remains were taken to the tomb in Novi Dvori in 1933 , by the wish of countess Anka Jelačić . During the night on July 24 , 1935 , the tomb was looted by unknown vandals
