The aim of my thesis is to create a list of structural and textural characteristics, and fossil content in the natural stone that Jože Plečnik used in Roman wall, Križanke and National and University Library. With the use of photogrammetry and TLS we made two different 3D models. Both techniques are credible, and comparable. The only problem occurred because of the lightning in NUK. The used stone is polished and the light reflects from the surface are affecting the quality of the 3D image. This is an obvious flaw, which for now, cannot be successfuly removed from the 3D model.
In Roman wall, the most frequently used stones are Carboniferous-Permian sandstone and conglomerate. In the stones, we can find many different structures/signs of weathering that were caused by atmospheric influences. Because of this, the fossils and other structures in the stones are not visible. We can find parallel and orbicular structures of weathering, as well as the flaking of magmatic rocks. The dominant rocks in Križanke are also Carboniferous-Permian sandstone and conglomerate. Besides them, we can also find flysch sandstone, bolzano porphyry and tufa. In the interior of Križake, there is also rudist limestone. In NUK, we mostly found Podpeč limestone with its diverse fossile fauna, black Lesno Brdo limestone and Hotavlje limestone. There is also marble, which can only be found in NUK.
