ABSTRACT
The main objective of this project was drawing of the technical documentation for the ribbed vaults of an auditorium (called “Lednice”) in the Old King Palace of Prague Castle and for the ribbed vaults in the Old Town Bridge Tower of the Charles Bridge. Both gothic ribbed vaults were built in 14th century in the Luxembourg era by the building mortar of the Petr Parler master builder. Both spaces were constructed on an irregular quadrangle ground plan, but it was evident that the used circular arcs have the same radius for the space from the provisional architecture exploration. The documentation based on the data measured by the 3D laser scanning technology was carried out for verification of this theory. We created 3D models of the spaces. We created specially the 3D models of the ribbed vaults and their feet, which have very interesting ending where individual arcs are ended in the different places. Ground plans and cross sections of the spaces were drawn after 3D modelling. The created outputs serve for examination of the ribs geometry, their construction technology and for needs of knowledge extension for more gentle and more accurate reconstruction of the gothic ribbed vaults of this era.
