Uprising, Karađorđe, was born, who made of Topola the political/administrative seat of the liberated part of Serbia. A monument unit reminds of his time, including the Barracks, the School, the remnants of the fortress Karađorđe's Town, with a tower, the Church from 1811 and the Inn ("Karađorđe's Castle"), in which the Historical Museum is situated. One of the greatest attractions in the Karađorđe's Castle is bronze cannon, the right handle of which was broken off, in order to make the crown for the Kinf Petar I Karađorđević during his crowning.
The Memorial Complex of the Karađorđević's on Oplenac had been constructed for almost three decades, by the drawings of the architect Kosta Jovanović. In the wonderful St. George Church, there are reproductions of the most beautiful frescoes of the Serbian Medieval Painting, produced by Paja Jovanović. They were done in mosaic and gold plated, which makes the Church one of the most beautiful Christian facilities. In the crypt under the Church, numerous members of the Karađorđević family were buried four rulers among them.
In addition to the Church, the Memorial Complex consists also of the King's Villa, the Village and Vineyard Keeper's House and other facilities. In one of them the ruler himself - King Petar had been living for many years, during the Church construction. At present, this building is simply called Petar's House. It includes a Gallery and the Endowment Management now. The most attractive of the displayed exhibits in the Oplenac Gallery is the composition The Secret Dinner, done in the white mother-of-pearl. There is an interesting story related to it. Namely, on the occasion of the burial of the King Aleksandar Karađorđević, in 1934, this work was noticed by Hermann Goering, one of the Third Reich leaders, and it was transported to Germany. It was returned to Topola only in 1947.
