He was also an honorary consul of Serbia in the United States from 1912 to 1920 and played a role in determining the borders of newly formed Kingdom of Yugoslavia.

In addition, the complex encompasses National House, which Pupin built with his funds for Idvor, and a museum, in the old elementary school building that he once attended.

The small room facing the street has been adapted to look as a studio, with several photographs of Mihajlo Pupin, his letters and personal things.

Its basis is symmetrical and there are central hall, two classrooms, annex rooms and two porches on the side of the school leading to the yard.

It exhibits the characteristics of simplified neo-classicist style flat lintels with the imitation of the arches, simple cornice and parapet plates.

In 1979, in the classroom at the right side of the entrance, the Museum of Vojvodina in Novi Sad has set an exhibition dedicated to life and work of Mihajlo Pupin, which stands to the present day.

It unravels the life story of the great scientist, starting with the first steps he had taken in his parents' home to the immense success he achieved in the US and in his homeland.

[2] The Home would be, according to Pupin ″not simply a lecture hall, but also school for the Idvor’s youth and other inhabitants to learn about growing fruit and vegetables″.

Mihajlo Pupin spoke for the first time about his intentions to finance the construction of the National Home in Idvor in the article called ″The Gardening Production″ published in the magazine the ″Privrednik″ (Businessman) in its November–December issue in 1933.

The portal is flanked by door frames and a lintel which were added in the 70s made of burnt clay by ceramist Delija Prvački.

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.

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.

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.

[13] At the October Meetings, a number of awards and recognitions are given for scientific work, invention and contribution to preserving the memory of the great scientist.

The awards are also given to primary and secondary school students from all over Banat who have achieved notable success at national and international competitions.
