Castrum Gariannonum, Roman coastal fort in Norfolk, England
Castrum Gariannonum is a Roman coastal fort in Norfolk featuring stone walls that rise approximately 4.6 meters high with a base thickness of about 3 meters. Six symmetrical bastions are distributed along the perimeter to strengthen the defensive structure.
The fort was built in the mid-3rd century and served until the early 5th century as a key component of the Saxon Shore defense system against sea raids. It played an essential role in protecting Britain's eastern coast from maritime threats during this period.
The site shows how it shifted from a military stronghold to a religious center after Roman forces left the region. Evidence of a timber monastery church and burial ground reveals how later inhabitants repurposed this location for spiritual life.
The site features wheelchair-accessible pathways that allow visitors to navigate the grounds comfortably. Information panels are placed throughout to explain the fort's structure and its role in ancient defense systems.
Medieval builders incorporated Chinese bricks into the nearby St Peter and St Paul Church, revealing that unusual materials were transported across vast distances. This detail shows how the site and surrounding buildings reflect different periods and cultural connections over time.
