About Burgh Castle Roman Fort
The Roman Fort at Burgh Castle is one of the best preserved Roman sites in Britain. Built between 260 AD and 280 AD, the walls of this impressive fortification remain in remarkably good condition – they survive on three sides and stretch as high as four metres.
Burgh Castle Roman Fort – known as Gariannonum – was originally built as part of the Saxon Shore defences, which were designed to act as a defensive system protecting against seaborne raiders from Denmark and Germany.
The forts acted as naval bases and defended trading centres and local settlements. Other Saxon Shore forts in the area are also located at Brancaster and Caister-on-Sea.
The walls of Burgh Castle Roman Fort were Originally around four metres wide and stood as much as four and a half metres high. They were fortified further by projecting towers or bastions which were used for catapults and ballistae – adding further firepower to the fort’s defences.
After the end of the Roman period, the site continued to be used by the Saxons with evidence of the site being used at one time for a monastery and later as a Norman fortification.
Today the remains of Burgh Castle Roman Fort are truly impressive; both for their state of preservation and for the located, situated as it is on a low cliff above the Waveney estuary. The site is operated by English Heritage and as well as exploring the ruins themselves, the site has a series of interpretation panels exploring the history of Burgh Castle.
