The height of this interface is about 39.1 meters and Oabulg of approximately 25.30 meters in width, and length of the columns on the first floor about 12.65 meters, the second floor is about 9 meters, while the jar above the kiosk stands at a height of 3.50 meters. Composed interface Treasury of two sections: the upper and department basement, with the triangle broken and ring the building, made up the bottom of the six columns, where the العامودين in the middle separated from the wall, and column capitals of the first kind, "vegetable", and there is some difference between the shapes of plant crowns , and superior columns Afrish the decorated pairs of winged beasts, including vases, and a tails curled trunks and tangled, and on both sides of the face of the highlights of the frieze plant leaves. Tops Triangle Shape (Pediment) disk sun between the horns and ears of wheat, which symbolizes the gods Isis (Isis) Egyptian, as we find in the center of the frieze face out of the papers Alokanthus, has been distorted, and top sides of the triangle stands animal winged, and show these shapes influence of civilization Egyptian terms of content, as we find when spaces side between the columns base topped by a carved, which is a form of human being standing in front of horse, and was carving forms of horses and camels in the arts Nabataean funerary clear, which is to help them to transfer the deceased on his journey to the afterlife. As for the upper part of the Treasury is composed of six columns front and eight columns background, which is attached to the walls and the capitals of the second type, "vegetable", and in the middle of the interface we ring the building The roof italics in the form of a tent, topped by a crown pillar and a jar, but Alafrish higher, they are decorated In addition to all of these motifs, we find between the columns front and rear, sculptures statues on the rules, has been distorted in a subsequent period, and in the mid-ring the building (Tholos) standing statue of the gods (Isis) with ears of wheat that symbolize her, the goddess of death of Egypt, on its side between columns find statues Triomphe, as we find the highest forms of sculptures triangles bird eagle. We find symmetry in the interface to a large extent, in terms of architectural decoration and engineering, with sculptures on the sides are not identical to each other, but they are consistent with each other or with the interface, so that was suitable for variety. Dahlman has been described (Dalman) and safe as the interface is made up of dual Temple, front and rear and placed on top of each other, the basement shows the entrance to the temple, and the top shows on the campus of the sacred (Sanctuary). He added that this combination has been imitated in the building of the monastery and the grave only Corinthian, which is against the traditions but appropriate for the place. Several theories have emerged for the safe descent, have tried a large number of researchers to find buildings like her, may be a source of inspiration for the safe design. It was found many that its origin back to the buildings of Alexandria, a temple Cleo Petra and the library, while noting Babinschr (Papenstecher) to the presence of ring the building (Tholos), in many private homes and palaces, where she was surrounded by arcades Baptist (), has been found Starkey (Starcky) The interface Treasury, reflect the architecture in the city of Alexandria, Egypt during the Hellenistic Period, and in any case, we find that this interface combines influences Eastern, represented in the gods and animals superstitious Egyptian, Syrian Eagle, the shape of the jar East, together with the methods Hellenistic, in addition to character Nabataean in forms and motifs crowns, frieze, and some sculptures properties between classical architectural elements. Like the lower part of the Treasury, a temple-style Corinthian six columns above the base low-rise, columns ending crowns fashioned Corinthian but it does not resemble crowns that we know in Jerash, and Baalbek, which returns to the second century AD, in which case we do not find only two rows of Paper Alokanthus, instead of the third row carving floral artist is extremely accurate, comes out of a pine cone, to occupy the middle flat or Alapacos. Above the columns extends حنت class ion, has broken between the last two columns on each side, and the frieze, which tops sculpture is also fashioned ion, consisting of floral motifs, animals legendary among Awan like pottery that abound in the graves, called pots tears (Lecmrimaria) . The Triangle Vicll four columns Central, not total columns, as is the case in the temples Romania, and within abound floral surroundings with a woman who has distorted his features, and can be likened to gods experience enlightenment, currently at the Museum of Oman, and in the top triangle substrate (Acrckrium) holds disk of the sun surrounded by the horns and ears of wheat, which is the slogan of the gods Isis Egyptian and HATOR gods that corresponds goddess Astarte When the Semites, and the triangle is based on the second round base decorated with a frieze of flowers, and statues of sphinxes at both ends.
