The subject of this paper is a corpus analysis of patrimoine in contrastive perspective with its Polish equivalent dziedzictwo within the framework of the intercultural approach in French language teaching. Its purpose will be to reveal the semantic differences and similarities of these two words in terms of the results provided by the frequency and collocation analysis based on the Polish National Corpus, the French Corpus Frantext and Corpora Collection of Leipzig University. The study showed that one of the strongest and most frequent collocations, indicated by different collocation measures, for both Polish and French, is cultural heritage (Fr. patrimoine culturel, Pl. dziedzictwo kulturowe). Typical Polish collocations are national heritage and Christian heritage, while in French these are patrimoine artistique et patrimoine touristique.
