The present work aims at the analysis of spatial constructions in the work of the English author J.R.R. Tolkien, entitled "The Lord of the Rings". The author himself is considered by many to be the father of fiction and has laid the foundations for the countless works of a similar literary genre that followed. His love of extensive spatial descriptions is one of the key features of his writing style.

The analysis is based on the first book of the trilogy, entitled "The Fellowship of the Ring", as it contains a large sample of these descriptions. In the creation of the "Secondary World", a fictional story, there are no real natural landscapes, but all the spaces have emerged from the design process and to serve a purpose. They can, therefore, be considered products of architecture, with the author being the architect of this whole imaginary world.

Thus, the study of the different uses of the landscape is attempted as a narrative means, so that the author and at the same time "architect", succeeds in consolidating and understanding the imaginary world he constructs. At the same time, it creates believable fiction, introducing cultural, folkloric and historical features, creating different atmospheres, directing the plot and defining its rhythm.

Through the process of isolating and recording the spatial descriptions from the rest of the project, a list of reports was also created, which is a tool to approach the space during this study. It was, however, ultimately a tangible proof of the importance of space in Tolkien's work, since, now that that space is cut off, it seems to form his own narrative.
