The article is devoted to the linguoculturological study of phraseological units representing the features of the expression of spatial relations in two genetically related Russian and Bulgarian languages. In the Russian and Bulgarian languages, based on the semantic analysis of phraseological units, three subgroups were identified: 1. "Far/close." 2. "Here/there." 3. "Bottom/top." The universality of the category space also shows that similar semantic groups and almost the same number of units were found in the languages we have considered.
