Castrum Gariannonum, Roman coastal fort in Norfolk, England
The stone walls of Castrum Gariannonum rise 4.6 meters high and extend 3 meters thick at their base, featuring six symmetrical bastions along the perimeter.
The fort operated from the mid-3rd century to early 5th century AD as part of the Saxon Shore defense system against maritime raids along Britain's eastern coast.
Archaeological excavations within the fort revealed a timber monastic church and cemetery, indicating its transformation into a religious center after Roman withdrawal.
The archaeological site maintains wheelchair-accessible paths throughout the grounds, with informational panels explaining the fort's structural elements and military significance.
Medieval builders incorporated Chinese bricks into the nearby St Peter and St Paul Church, demonstrating the site's continuous architectural evolution through centuries.
