Building stone is during its “life” influenced by actions of weathering processes which usually lead to changes in the internal structure of the stone which influences its durability. For this reason, studies of a stone internal structure are very important. There are many methods to determine effective porosity and provide porosity values in a percentage, nevertheless, these methods do not enable visualization of the internal structure. The visualization can be useful for better understanding of the durability phenomenon. Therefore, the methods of X-Ray microtomography and microscopy in ultraviolet light were used in our research of three Czech sandstones. Both methods also provide different values of porosity which are given due to their limitation. The main aim of this contribution is to present basic information about both methods and to compare their results, advantages and disadvantages.
