The interesting pavilion is in the Serbian-Byzantine style and was constructed on the designs of the engineer Professor Tanaseric of the University of Belgrade. The plan is arranged around a single nave. The faade of the building is designed around elongated arches, shaped by arabesque friezes, painted and in stucco. These arches are horizontally crossed by alternating polychrome strips. Five little cupolas, tinted greenish, of which the central one is the tallest and most slender, decorate the building – original and charming in its distinctly exotic air. In front is an elegant terrace from which one can enjoy the magnificent panorama.

The Siamese pavilion digresses completely from the general architecture of the Fair, keeping thus a markedly exotic sense. This project was studied in Bangkok, in the offices of the Public Works Department by the architects Annibale Rigotti and Mario Tamagno. It is from the same architecture of the Siamese churches (Watt) with large, polychrome roofs, in the so-called binocular style and with the golden dome (phrachady). It has a total length of 65 meters and a height – from the top of the tallest pole – of 45 meters. The pavilion is composed of three-closed room and three open galleries. The building of the Pavilion was undertaken by Mr Previgliano. The Exhibition of Siam draws the attention of all the visitors in a special way since it brings us the echo of the life and civilization of mysterious and evocative regions of the Orient
