Sant Climent de Taüll has a basilica plan structure, which is similar to early Christian architecture such as the Roman basilica of Leptis Magna and the Basilica of Old St. Peter. Similar to early Christian architecture, Sant Climent de Taüll has a central nave and an apse. The difference is that Sant Climent de Taüll has three naves and three apses, and a bell tower, whereas early Christian architecture has side aisles, transepts, a narthex and an atrium. In addition, the Santa Maria Maggiore, a basilica in Rome, has a clerestory, whereas the Sant Climent de Taüll is the opposite because it has very few windows.
