Ambrosius Aurelianus
Excavations in 1910 and 1954–56 revealed several periods of habitation at the site. The earliest elements date to the Iron Age, perhaps to the 1st or 2nd century. A pool within the enclosure, thought to be an artificial construction, may date to this phase. It is perhaps connected to the pool found in the popular tale of Vortigern and the dragons. Other traces suggest habitation into the 5th century, which would put it in the time frame for Vortigern and Ambrosius Aurelianus.
