The aim of this research is to analyse the structure of three-word Lexical Bundles in the Journal of Cultural Heritage articles vol.55. The data were collected by using the documentation method, then analysed by using classification as conducted by Hajar. The result of the research is 23 lexical bundles were only structurally grouped into eight structure forms. They are Noun phrases with of-phrase fragments (the development of, the level of, the use of, the case of, a range of), Noun phrases with other post-modifier fragments (such as the), Other prepositional phrase (fragment) (in many field, in most cases, an increase in, of cultural heritage, of the sample, of an object), Anticipatory it + verb phrase/adjective phrase (it has been), Passive verb + prepositional phrase fragment (are typically used, have been carried), Copula be + noun phrase/adjective phrase (due to the, has an important, prior to discovery, are found in), to-clause fragment (to meet the, to their long), and Other expressions (as well as, and can be). Based on the data, the researcher draws the conclusion that structure Other prepositional phrase (fragment), which included six bundles, was the most structural form of lexical bundles employed in those articles. They are "in most cases, an increase in, of cultural heritage, of the sample, of an object". The bundle has been used frequently in almost all articles in the journals of cultural heritage introductions. The outcome of this article is anticipated to include references to analyse of the lexical bundle's structure.
