Caer Gwinntguic

Caer Gwinntguic was a late antique / early medieval British kingdom which had its center in the Roman city Venta Belgarum (now Winchester, Hampshire) and the historic lands of the Belgae tribe. It acquired its own form of independence at the beginning of the fifth century as a result of the Rescript of Honorius, which left the inhabitants of the westernmost area of ​​the Saxon Shore to organize their own defense.[1][2][3]
