Question about Moldavian architecture

The Moldovan Pavilion at the Agricultural Exhibition in Moscow featured unusual twisted columns with bizarre hammer-shaped capitals. Information regarding Moldovan architecture on the internet is scarce—is this model based on a real design that exists in Moldovan architecture?

The arcade and the frieze with reliefs above it, as well as the overall structure of the building, are clearly Greco-Roman, but the columns are simply too different. The other buildings on the exhibition grounds utilize stylized Greek, Egyptian, and Persian columns with a "Soviet touch," but these look like nothing I have ever seen before.

I have concluded that these must be derived from Moldovan tradition, as the window portals on the side wall are clearly from there, and the pavilions of other republics also utilize national elements; however, I haven’t been able to find anything similar to them. Internet searches for "Moldovan architecture" mostly return images of vaguely Byzantine-style churches.

I am researching late Socialist Classicism architecture, and VDNH is its pinnacle, completed shortly before the USSR transitioned to Modernism. It is particularly interesting how it blended traditional motifs with classical architecture.
Does anyone know what these are and what terms I should use to find information about them?
