Do four columns constitute a basilica? The church of St Peter of Tarragona in Late Antiquity

The aim of this article is to afford a new vision about the archaeological discussion of Late Antique church of Saint Peter of Tarracona, mentioned in the Liber orationum festivus, named as ‘Oracional de Verona’ and dated to the beginning of 8th century. It’s an analysis based on the application of new graphic documentation techniques around the Rovellat and dels Àngels squares of current city. Their results allow us to propose the exact location and partial restitution of a church that has been frequently mentioned in recent research.
