area at the time, but it never became a university that Pupin intended it to be. The National House was used as a Cultural Center, a place where were organized various events, film screenings and local political gatherings until 1979. For some time after the Second World War, it was used as a warehouse for storing wheat. The architectural style exhibits neo-classicism characteristics. The front is divided by pilasters, entrance portal and a fronton in the upper section of the building. The portal is flanked by door frames and a lintel which were added in the 70s made of burnt clay by ceramist Delija Prvački. There is Pupin's bust, a work of the sculptor Ivan Meštrović in the niche, above the entrance doors. Aside from the 150-seat hall with a gallery, a stage and offices, there are also a library, electric power generator and a radio system that could reach the entire Idvor. The Home has a sewage system which is functional at present day. In 1979, on the occasion of the celebration of the 120th anniversary of Pupin's birth, a new building of the Cultural Center was built next to the National House, according to the project of the architect Bogdan Bogdanović. It is a reinforced concrete construction with a hall of 300 seats and annex premises. Tourism The memorial complex in Idvor is included in the tourist offer of Serbia. The offer includes a tour of Pupin's birth house, museum exhibits in the old school and the People's House of Mihajlo I. Pupina. The tours are led by an expert guide, the curators of the Pupin Museum, who have developed a different program for different ages of visitors, which makes the visit interesting for the tourists themselves. The tourist tour of Idvor also includes the graves of Mihajlo Pupin's parents in the cemetery located at the western end of the village and the Old Cross, which is located on the site of the original settlement of Idvor, which was located north of today. The cross was erected in 1839 on the site of the old church. Every year, the Memorial Complex is visited by more than 10,000 visitors, mostly students on excursions.
