Ianus Augustus, Caput Viae (Mengíbar, Jaén): An interprovincial monumental border in Roman Hispania

Abstract

Recent research undertaken as part of the Iliturgi Project has located the remains of an Early Imperial building complex linked to the Via Augusta. They include the foundations of an arch and a monumental platform whose size and characteristics allow it to be identified as the Ianus Augustus, a monumental complex near the River Baetis that marked the limit between the Roman provinces of Baetica and Tarraconensis. Its location makes it a reference point for our knowledge of the ancient geography of Hispania and for understanding Roman interprovincial frontiers. Geophysical prospections in its surroundings have also revealed the possible remains of a bridge across the river.
