Caerleon Legionary Fortress

Excavations at Roman Isca

Since 2006, archaeologists have been undertaking a series of surveys and new research excavations at Caerleon. This website gives details of past, present and future work at the fortress of Isca, home of the Legion II Augusta for nearly 300 years during the Roman occupation of Britain.

Excavations in 2011: Caerleon's 'Lost City' of the Legion

Cardiff University recently undertook trial excavations in the area of newly-discovered monumental buildings outside the fortress, on the banks of the River Usk. This area of settlement outside of the walls (known as the canabae to the Romans) might be a major harbour facility, or a series of official and/or religious buildings.

Priory Field Excavations 2007-2010

Cardiff University and UCL undertook a series of excavations in Priory Field, in the southern part of the fortress enclosure, between 2007-2010. After one season of trial excavations in 2007, this project focused on the examination of one wing of a large, square warehouse building. During the summers of 2008 and 2010, this building gave up many of its secrets, including a great deal of information about the equipment of the legionaries, and also an important story of late and post-Roman life in Caerleon.

Although this dig has now been completed, this website will be updated with reports of our progress in looking at the finds in more detail over coming months.

This project, directed by Dr Peter Guest and Dr Andrew Gardner, has been generously supported by Cadw, Cardiff University, UCL, National Roman Legion Museum, and many members of the Caerleon community.
